        * Makefile.am: Add build rules for ppc64.
        This avoids the build failing at pedump with unresolved symbols

2008-07-28  Bill Holmes  <billholmes54@gmail.com>

        * mini-amd64.c (get_call_info): Winx64 fix for passing floats.
          The float param registers and other param registers must be the 
          same index on Windows x64.

        * mini-amd64.c (mono_arch_allocate_vars) : Implementing the 
          ArgValuetypeAddrInIReg argument case.  Setting the argument
          op to OP_VTARG_ADDR (OP_REGOFFSET)).

        * mini-amd64.c (mono_arch_call_opcode) : Winx64 fix.  Use the size
          variable computed above as the copy length for arguments of storage
          type ArgValuetypeAddrInIReg.

        * mini-amd64.c (mono_arch_emit_call) :  Implementing the 
          ArgValuetypeAddrInIReg argument case.  This case will rely on
          mono_arch_emit_outarg_vt to emit the correct code later in the process.

        * mini-amd64.c (mono_arch_emit_call) :  On Winx64 there always needs to be
          a 32 byte stack allocation for all calls.  We will omit the adjustment for
          jump and tail call instructoins as they do not follow the typical call behavior.

        * mini-amd64.c (mono_arch_emit_outarg_vt) :  Implementing the case for
          ArgValuetypeAddrInIReg.  The code emitted will copy the argument to a 
          local variable and pass the local variable by reference to the called method.

        * mini-amd64.c (mono_arch_emit_prolog, emit_load_volatile_arguments) :
          Implementing the ArgValuetypeAddrInIReg argument case.  When the address
          of a struct is passed in a register it must be saved with the other
          volatile argument on the stack.

        * mini-amd64.c (mono_arch_emit_prolog) : Winx64 fix.  When omitting the
          frame pointer the stack adjustment value must be saved to the unwind 
          info structure.

2008-05-06  Rodrigo Kumpera  <rkumpera@novell.com>

        * driver.c (mono_main): Revert r102623. The right
        thing to do is to enable the verifier under verifiable
        unless a --security flag was passed.

        We need this non-trivial behavior for --verify-all otherwise
        mcs-compileall won't be able to use it. As it needs everything to
        be verified under validil.

        * mini.c (mono_method_to_ir): Verify visibility of call related opcodes
        against both inflated and non-inflated methods. We need to check against the
        generic definition for cases where the instantiated method is not visible.
        We need to check against the inflated types for cases where the instantiation
        changes any super type. This fixes #382986.

        Note that this doesn't need to be applied to other parts of mono_method_to_ir
        that check for visibiliy as generic params only appears as the type subject
        of tokens on call opcodes. Field manipulation and ldftn must always
        target an exact type.

2008-05-06  Rodrigo Kumpera  <rkumpera@novell.com>

        * driver.c (mono_main): Using --verify-all enables the verifier under validil mode

        trampline.

        * mini.c, mini-amd64, mini-x86.c, mini-exceptions.c: Pass the
        vtable instead of the RGCTX to static methods.

2008-04-08  Massimiliano Mantione  <massi@ximian.com>
        
        aliasing.c (update_aliasing_information_on_inst): Fixed a bug which
        shows up when both MonoInst arguments can cause aliasig.
        There is likely no way in the current JIT to trigger this problem, but
        it showed up in the development of generics sharing, when in a new
        opcode both args of an OP_GROUP can be aliases (addresses of a local).
        When the generics sharing code will be committed, its tests will be
        valid also for this bug.

        determined by the vtable displacement of the call.

Mon Oct 15 10:35:12 CEST 2007 Paolo Molaro <lupus@ximian.com>

        * mini.c, mini.h: register the common vtable trampoline if the

        allows open types if given a generic sharing context.
        mini_get_basic_type_from_generic() takes a
        MonoGenericSharingContext* instead of a MonoCompile* now.

        debugger even if the binary is stripped.

        * debug-debug.c: Reference the `MONO_DEBUGGER__debugger_info_ptr'
        from the `.mdb_debug_info' here to prevent the linker from
        removing that section.

        MONO_DEBUG=1 when running Mono. 

        This takes also care of parts of the leaks as seen by Joe.

        left in by mistake.

        * driver.c (EXCLUDED_FROM_ALL): Disable SSAPRE until bug #70637 is 
        fixed.

        * mini-sparc.h mini-sparc.c: Enable out-of-line bblock support.

        * tramp-*.c: Only patch vtable slots if the object is in the current
        domain. Fixes appdomain-unload.exe.

        * mini-amd64.c mini-amd64.h: Enable out-of-line bblock support.
        
        * mini-amd64.c (mono_arch_local_regalloc): Port regalloc fix from
        x86 branch.

2005-01-05  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (reverse_branch_op): New helper function.

        * mini.c (optimize_branches): Run the new optimization only on 
        platforms which support it. Also reverse all kinds of branches.

        * mini.h (MonoBasicBlock): Add 'out_of_line' field.

        * mini.c (mono_method_to_ir): Set 'out_of_line' for bblocks which have
        a throw statement.

        * mini.c (optimize_branches): Reverse not-equals branches if the false
        bblock is a throw. This happens a lot of time with argument checking in
        corlib.

        * mini.c (mono_codegen): Add support for placing basic blocks after
        the function epilogue.

        * mini-x86.c mini-x86.h: Add support for placing basic blocks after the

        supports ITIMER_PROF.

2005-01-05  Zoltan Varga  <vargaz@freemail.hu>

        * mini-x86.c (mono_arch_local_regalloc): Fix a bug introduced by the

        * aot.c (emit_method_info): Increase size of temp buffer.

        * mini-x86.c cpu-pentium.md mini.c: Load fp constants differently in 
        the AOT case.

2004-12-28  Zoltan Varga  <vargaz@freemail.hu>

        * aot.c (emit_method_info): Fix build.
        
        * aot.c: Further rework of the AOT file format to reduce the size of
        the method info data.

        * mini.h: Bump AOT file format version.

2004-12-27  Martin Baulig  <martin@ximian.com>

        * mini.c (mini_get_method): New static method; call
        mono_get_method_full() and mono_get_inflated_method().
        (mono_method_to_ir): Use mini_get_method() instead of
        mono_get_method_full(). 

2004-12-26  Patrik Torstensson  <patrik.torstensson@gmail.com>

        * mini-x86.c (atomic ops): fixed bug interlocked bug #70784. 

2004-12-25  Zoltan Varga  <vargaz@freemail.hu>

        * inssel.brg (ldind_to_load_membase): Handle CEE_LDIND_I8.

        * inssel-amd64.brg: Add some optimization rules.

2004-12-24  Ben Maurer  <bmaurer@ximian.com>

        * aot.c: Remove the use of MonoGHashTable and other GC stuff. The
        standard not GC'd stuff is fine.

2004-12-24  Zoltan Varga  <vargaz@freemail.hu>

        * aot.c: Rework the AOT file format to get rid of most of the global
        symbols. This reduces the size of the mscorlib.dll.so by 1MB.

        * mini.h: Bump AOT file format version.
        
2004-12-23  Zoltan Varga  <vargaz@freemail.hu>

        * mini.h: Bump AOT file format version.

        * aot.c (mono_aot_is_got_entry): New function to determine if an

        might involve a got access.
        
        * mini.c (get_method_from_ip): Another debug helper function.

        * mini.c: Call mono_get_got_var () in a couple places. Handle the case
        when got var accesses are created during the decompose phase.

        * mini-sparc.c: Change mono_compile_aot to cfg->compile_aot.

        * mini.h mini.c mini-x86.c aot.c mini-sparc.c: Add a 'compile_corlib'
        argument mini_compile_method and to MonoCompile, and use this to
        determine whenever a given method is compiled for AOT. This allows the
        other methods compiled during AOT compilation to be free of AOT stuff,
        so the backends does not need to add special support for them by
        creating a fake GOT etc.

        * mini-x86.c (mono_arch_patch_code): Remove fake got stuff as it is no
        longer needed.

2004-12-21  Ben Maurer  <bmaurer@ximian.com>

        * mini.c (mono_method_to_ir): It turns out that some of the
        x-appdomain wrappers are lax with types, so just ignore this for
        all wrappers.

        * inssel.brg (OP_CHECK_ARRAY_TYPE): Optimize this by only looking
        at the vtable->klass. If it is non-shared code we can just use the
        vtable.

Tue Dec 21 17:43:06 CET 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c: access MonoDomain from tls, too.

        * iltests.il: New test for LDELEMA on an array of ref types.

        * mini.c (CEE_LDELEMA): We need to emit OP_CHECK_ARRAY_TYPE for
        all ldelema's on reftypes.
        (check_call_signature): Remove the OP_CHECK_ARRAY_TYPE from here,
        it was the wrong place to put it.

        * mini-x86.c (mono_arch_output_basic_block): Just use ecx as the
        register to pop to make this cleaner, at the request of Paolo.

2004-12-20  Ben Maurer  <bmaurer@ximian.com>

        * mini-ops.h (OP_GETHASHCODE): New op.

        * inssel.brg (OP_GETHASHCODE): Emit code for the new opcode

        * mini.c (mini_get_inst_for_method): Create the intrinsic hash
        operation.

        For a microbenchmark, this reduces the cost of Hashtable.get_Item
        by 25%.
        
        * mini-x86.c (mono_arch_output_basic_block): Rather than

        add ebp, 4

        Emit

        pop edx

        The first is 3 bytes while the second is 1. This saves 36 kb on
        mscorlib, quite a big saving. When bootstraping mcs, I was able to
        see a small boost because of icache locality.

        * cfold.c (FOLD_BINOPCOMM): Kill add foo, 0

Mon Dec 20 12:19:40 EST 2004 Paolo Molaro <lupus@ximian.com>

        * Makefile.am, mini-ppc.h, mini-exceptions.c, exceptions-ppc.c:

         mini-amd64.c, mini-x86.c, cpu-pentium.md: renamed OP_X86_TLS_GET
        to OP_TLS_GET.

2004-12-20  Sebastien Pouliot  <sebastien@ximian.com>

        * declsec.c|h: Added functions to cache the declarative stack modifiers
        in MonoJitInfo and to create a security frame from a MonoJitInfo 
        structure.
        * mini.c: Initialize jinfo->cas_inited to FALSE when MonoJitInfo is
        created. Register internal calls for System.Security.SecurityFrame::
        _GetSecurityFrame and _GetSecurityStack.
        * mini.h: Added definition for new icalls (in mini-exceptions.c) and
        the definitions for the new stack walk/callback mechanism.
        * mini-exceptions.c: Added internal call GetSecurityFrame (to get the 
        first security frame for LinkDemands and InheritanceDemands) and
        GetSecurityStack for Demands. Both use the new mono_walk_stack code
        from lupus.
        * mini-x86.h, mini-amd64.h, mini-sparc.h: Architecture specific stack
        walk initialization (lupus).

2004-12-20  Ben Maurer  <bmaurer@ximian.com>

        * mini.c (mono_method_to_ir): In CEE_DUP, handle the dup / stloc
        idiom.
        (handle_loaded_temps): Do not create a temporary variable for
        things that we know are temps. They will never be modified.
        (mono_spill_call): Set MONO_INST_IS_TEMP
        (mono_emulate_opcode): ditto
        (emit_tree): ditto
        (mono_method_to_ir.CEE_DUP): ditto

2004-12-19  Ben Maurer  <bmaurer@ximian.com>

        * mini.c (type_to_eval_stack_type): Make this handle the void type
        (mono_emit_call_args): set the call->type with type_to_eval_stack_type
        (emit_tree): use ip_in_bb to special case some common idioms
        Update all callers to pass in the IP.
        (mono_method_to_ir): Make CEE_CALL* do the above as well.

        This gives us a nice 2% speedup in mcs bootstrap.

        * mini-x86.c (peephole_pass): Peephole pass to make
        mov  [foo], eax
        push [foo]

        into

        mov [foo], eax
        push eax

        * mini.c (ip_in_bb): new method.
        (mono_method_to_ir): use this method rather than doing the hash
        lookup ourselves.

        * linear-scan.c (mono_linear_scan): When expiring actives, you
        don't need to keep around variables that expire on this
        instruction. This makes it so that:
             a = b + 1
        will turn into:
             store (ebx add (ebx, 1))
        which will become
             add ebx, 1

2004-12-19  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_method_to_ir): Optimize the common ldobj+stloc

        changes from the x86 code.

        * mini.h: Add prototype for mono_arch_get_throw_corlib_exception ().

2004-12-16  Zoltan Varga  <vargaz@freemail.hu>

        * mini-x86.c (mono_arch_emit_epilog): Optimize the corlib exception
        throwing code to reduce its size, unify the AOT and non-aot code and 
        get rid of relocations in the AOT case.

        * mini-x86.h mini.c exceptions-x86.c 
        (mono_arch_get_throw_corlib_exception): New arch specific function to 
        raise corlib exceptions which doesn't require relocations in the 
        caller.

        * aot.c (emit_method): Handle PATCH_INFO_NONE as well.

2004-12-15  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_emit_method_call): Only allocate the got var when it is
        needed.

        * mini-x86.c (mono_arch_patch_code): Add missing PATCH_INFO_METHOD_REL
        in the AOT case.

2004-12-14  Patrik Torstensson  <patrik.torstensson@gmail.com>

        * mini-x86.c, cpu-pentium.md, inssel-x86.brg: Fixed bug
        with add function when used from Inc/dec atomic 
        functions. Re-enabled optimization on x86.
        * mini-ops.h: renamed atomic_add functions to
        allow _add to match the Interlocked::Add and
        _add_next to match Interlocked::Inc/Dec.

2004-12-15  Massimiliano Mantione  <massi@ximian.com>

        * mini.c: Fixed a subtle bug in mono_method_to_ir, about the
        linking of BBs to the end BB, and enabled SSAPRE also with
        consprop and copyprop (which was prevented by that bug).

2004-12-14  Patrik Torstensson  <patrik.torstensson@gmail.com>

        * mini-x86.c: disabling the Interlocked optimizing code.

        * mini-x86.c, inssel-x86.brg, cpu-pentium.md: removed _imm 
        interlocked optimization due lack of support on x86, rewrote 
        exchange to take into account that base may be in eax.
        
        xsp works again; activated Interlocked optimizing code.
        
2004-12-14  Zoltan Varga  <vargaz@freemail.hu>

        mono_arch_get_aot_patch_offset () to mono_arch_get_patch_offset () and
        make it work with all kinds of patchable code.

        * inssel.brg inssel-x86.brg: Add new rules dealing with computing the
        address of the GOT, and referencing entries in the GOT.

        * mini.c (mono_method_to_ir): Only call mono_debug_init_method()
        if we are the "real" method, ie. not an inlined method inside it.

2004-12-11  Ben Maurer  <bmaurer@ximian.com>

        * mini.c (CEE_LDSFLD): Make sure that the vtable has been init'd
        before we look in the special fields table. This fixes
        ../tests/thread-static-init.cs.

2004-12-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * mini.c: return immediately after setting OP_ARRAY_RANK or CEE_LDLEN
        for Array get_Rank and get_Length. Fixes bug #70465.

2004-12-11  Zoltan Varga  <vargaz@freemail.hu>

        * mini.h mini.c aot.c: Put the bblock table for a SWITCH patch into a
        separate structure to reduce the size of MonoJumpInfo.

Fri Dec 10 18:09:22 CET 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c (mini_get_inst_for_method): Changed to allow ports
        to return a MonoInst instead of opcode 
        (renamed mini_get_opcode_for_method to better reflect the new functionality)
        
        * mini-[x86|s390|s390x|ppc|sparc].c (mono_arch_get_inst_for_method): 
        Allow ports to return a created MonoInst instead of op-code, will enable
        new optimizations.

        Fixes #69985.

2004-12-08  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): In CEE_CALLVIRT, use `fsig->signature'
        if we're a CEE_CONSTRAINED call.  Fixes gen-118.cs.

2004-12-08  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c (mono_arch_output_basic_block): Implement OP_FCONV_TO_<X>
        correctly.

        * exceptions.cs: Disable some tests which depend on properties of x86 fp
        arithmetic.

        * mini.c (mono_method_to_ir): In CEE_CALLVIRT, added support for
        virtual generic methods.  We call a special helper_compile_generic_method()
        icall to retrieve the method from the vtable, inflate and compile
        it and then do a CEE_CALLI.  Thanks a lot to Paolo for this idea.

        * jit-icalls.c (helper_compile_generic_method): New JIT icall.

2004-11-30  Zoltan Varga  <vargaz@freemail.hu>

        Fixes gen-112.cs.

2004-11-28  Martin Baulig  <martin@ximian.com>

        * mini-x86.c (mono_arch_call_opcode): Use the original type, not
        the result of mono_type_get_underlying_type() to check whether
        we're byref.

2004-11-26  Martin Baulig  <martin@ximian.com>

        * mini.c
        (mono_method_to_ir): Use `!method->signature->has_type_parameters'

        * mini-amd64.c (mono_arch_output_basic_block): Avoid doing virtual 
        calls through R11 since it is clobbered by the trampoline code.

2004-11-26  Raja R Harinath  <rharinath@novell.com>

        * Makefile.am: Consistently use $(RUNTIME) rather than ./mono to
        pick up in-tree mscorlib.dll.

        * aot.c: Rename MonoAOTModule->cleanup to out_of_date.

        * mini-amd64.c aot.c: Switch to PIC relative AOT code. References to 
        runtime data/code are now stored in a table similar to the GOT in ELF. 
        This allows the code itself to be position independent.

        * aot.c: Fix loading of referenced assemblies after the lazy assembly
        loading changes.

        * aot.c: Attach ELF type (object/function) directives to all global

        * mini.c (mono_method_to_ir): Don't allow any uninflated generic methods.

2004-11-24  Martin Baulig  <martin@ximian.com>

        * minit.c (type_to_eval_stack_type): Set `inst->klass' to the
        original klass (this only applies for generic instances).

2004-11-24  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): Use `STACK_OBJ' instead of
        `ldind_type [CEE_LDIND_REF]' (which would be beyond the end of
        that array).

2004-11-24  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_method_to_ir): Disable inlining for methods containing
        localloc. Fixes #69678.

        used SSE registers on pinvoke calls. Fixes #69774.

2004-11-23  Geoff Norton  <gnorton@customerdna.com>

        * inssel-ppc.brg, mini-ppc.c: Use mono_class_from_mono_type instead of
        vt->inst_vtype->data.klass.  This fixes generic structs and bug #69766

2004-11-23  Raja R Harinath  <rharinath@novell.com>

        * Makefile.am (MCS,ILASM): Don't refer to runtime/ directory.
        Refer directly to the mcs/ tree.

2004-11-19  Neale Ferguson <Neale.Ferguson@SoftwareAG-usa.com>

        * mini-s390.c, tramp-s390.c, mini-s390.h: Add LMF processing for trampolines.

Fri Nov 19 17:34:21 CET 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c, cpu-g4.md: set to zero the memory allocated
        with localloc if needed. Throe arithmetric exception in
        div an rem if needed. Implement ovf checks in OP_LCONV_TO_OVF_I.
        Adapted from a patch by Geoff Norton  <gnorton@customerdna.com>.

2004-11-19  Geoff Norton  <gnorton@customerdna.com>

        (ILASM): New.
        (%.exe): Use $(ILASM).

Fri Nov 19 14:54:07 CET 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c: adjust initial prolog size (bug #69691).

2004-11-18  Zoltan Varga  <vargaz@freemail.hu>

        * cpu-pentium.md (localloc): Increase max instruction len. Fixes

2004-11-12  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c mini-*.h: Get rid of MONO_ARCH_HAVE_RETHROW since all architectures support it now.
        (mini_init): Get rid of it from here too.

Thu Nov 11 20:17:17 CET 2004 Paolo Molaro <lupus@ximian.com>

2004-11-10  Martin Baulig  <martin@localhost>

        * mini.c (mono_method_to_ir): Use `generic_container->context'

2004-11-07  Ben Maurer  <bmaurer@ximian.com>

        * tramp-*.c: we no longer support icalls without wrappers, so
        a bit of code can be removed here

2004-11-07  Zoltan Varga  <vargaz@freemail.hu>

        * exceptions-sparc.c (get_throw_exception): Fix more bugs in previous
        patch.

        * cpu-sparc.md: Add op_rethrow.

        * exceptions-sparc.c (get_throw_exception): Fix bug in previous patch.

        Makes the output much easier to read

2004-11-05  Ben Maurer  <bmaurer@ximian.com>

        * ssa.c: allocate MonoMethodVar.uses from the mempool. First, this
        prevents another huge leak when compiling with ssa. Secondly, the
        performance of doing this rather than freeing the lists is much
        better. GList does a lock every time you allocate a list link,
        so that it can use a memory pool. So, it is better to just use
        a memory pool of our own.
        
        * ssa.c, linear-scan.c: replace g_list_remove_link with
        g_list_delete.  The remove one does not free the GList, so we were
        leaking memory. On -O=all --compile-all with corlib, this cut down
        3 MB of allocations.

        * mini.c: Fix pointer overwrite in mini_method_compile.

2004-11-2  Geoff Norton  <gnorton@customerdna.com>

        * inssel-ppc.brg (OP_OUTARG_VT (CEE_LDOBJ (base))):
        The darwin ABI needs some special handling for 1 and 2 byte structs
        Lets use lbz/lhz instead of lwz everywhere.
        * mini-ppc.c (calculate_sizes):  The Darwin ABI needs from special handling
        for 1 and 2 byte structs and struct which are size >= 3 || size % 4 != 0.
        Use stb/sth for the former, and put the latter always on stack instead of in
        argument registers.

2004-10-30  Zoltan Varga  <vargaz@freemail.hu>

        * trace.c (is_filenamechar): Add '_'.

        depends on libmonogc. Fixes #68805.

2004-10-26  Miguel de Icaza  <miguel@ximian.com>

        * mini.c (mono_jit_free_method): Provide extra information for
        this error.  Currently this leaks, but will be turned into a
        developer option in the future.

2004-10-26  Zoltan Varga  <vargaz@freemail.hu>

        * driver.c (mono_main): Applied patch from Willibald Krenn <willibald.krenn@gmx.at>. Make --graph work for icalls and pinvoke methods.

        * mini.h: Bump AOT version number.

        * objects.cs: Add another test for unbox trampolines.

        * tramp-amd64.c (amd64_magic_trampoline): Disable patching of trampolines for 
        valuetype methods.

2004-10-20    <vargaz@freemail.hu>

        * mini-ppc.c (calculate_sizes): Marshal valuetypes for pinvoke
        methods as their native size, fixed bug #57543, #57545.
        * mini-ppc.c (mono_arch_output_basic_block): Use mulli for imm16 types
        This saves a temporary register and mullw call down into 1 (minor perf
        increase for cases like sum = sum * 5;  This use to translate into:
            li r11,5
            mullw r28,r28,r11
        It now translates to
            mulli r28,r28,5

2004-10-15  Zoltan Varga  <vargaz@freemail.hu>

        * trace.c (mono_trace_eval): Use mono_method_desc_full_match. Fixes

        be a CBO.

2004-09-28  Lluis Sanchez Gual  <lluis@novell.com>

        * mini.c: Use mono_thread_exit() to stop threads, instead of ExitThread.

2004-09-28  Zoltan Varga  <vargaz@freemail.hu>

        * driver.c mini.h trace.c: Move the setting of the main assembly into

        * inssel-ppc.brg: arguments on the stack are always
        relative to the stack pointer (spotted by Neale Ferguson).

2004-07-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * exceptions-x86.c: delay appending the method name to the trace until
        after mono_jit_info_table_find is called, as this gets the real
        MonoMethod.

2004-07-09  Ben Maurer  <bmaurer@ximian.com>

        * aot.c: register roots

2004-07-09  Atsushi Enomoto  <atsushi@ximian.com>

        * aot.c : I could just use PLATFORM_WIN32 flag.

2004-07-09  Atsushi Enomoto  <atsushi@ximian.com>

        * aot.c : Reverting the previous fix. This time it broke linux build.

2004-07-09  Atsushi Enomoto  <atsushi@ximian.com>

        * aot.c : quick cygwin build fix. mkdir() with two args does not exist.

2004-07-08  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (handle_stack_args): Remove some more debugging code.
        
        * mini.c (handle_stack_args): Remove debug output left in by mistake.

        * driver.c mini.h aot.c: Allow additional options to be specified with
        --aot and pass them to mono_compile_assembly.

        * aot.c: Add experimental code to AOT compile all loaded assemblies
        on demand and save the code into a cache in the filesystem.

        * aot.c: Add support for more wrapper methods.
        
        * mini.c (handle_stack_args): Handle some corner cases. Fixes 
        58863.

        * cpu-*.md: Remove removed opcodes.

        * mini.h mini.c: Move JIT icall handling to icall.c. Replace usage of
        CEE_MONO_PROC<x> with CEE_MONO_ICALL. Move registration of marshalling
        related icalls to marshal.c.

2004-07-06  Zoltan Varga  <vargaz@freemail.hu>

        * mini-ops.h: Add OP_SAVE_LMF and OP_RESTORE_LMF.

        * Makefile.am (EXTRA_DIST): Add inssel-long[32].brg.

        * inssel.brg: Fix warning. Add rules for SAVE_LMF and RESTORE_LMF.

2004-07-06  Ben Maurer  <bmaurer@ximian.com>
        * liveness.c: If liveness is recomputated we need to reset the information
        for each variable. This way, if the liveness range has been narrowed
        by optimizations that happened after the last computation, we can return
        a smaller range.
        
        For example, if you have
        
        {
                int i = 0;
                
                // Tons of code that does not affect i
                
                i = foo ();
                ...
        }
        
        i = 0 is dead code and will be removed by SSA. However, when
        linear scan gets to the code, i will still appear to be live
        throughout the entire block. This prevents good register allocation.

2004-07-06  Martin Baulig  <martin@ximian.com>

        * debug-mini.c (mono_debug_init_method): Allow
        MONO_WRAPPER_MANAGED_TO_NATIVE wrappers.

Mon Jun 28 18:05:09 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c: reinstated mono_compile_get_interface_var()
        on x86, too, since the change breaks the Gtk# build there as well.

Fri Jun 25 17:36:28 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * driver.c: remove loop from the default optimizations: it seems to
        interact badly with some of the other options (see bug #60613).

2004-06-25  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c mini-x86.h mini-x86.c: Applied patch from Guenter Feldmann

        vararg-using methods.

2004-06-21  Martin Baulig  <martin@ximian.com>

        * mini/mini-exceptions.c
        (mono_handle_exception): Added `gpointer original_ip' argument.
        After calling mono_unhandled_exception(), call
        mono_debugger_unhandled_exception() and if that returns true,
        restore the context and return.

Mon Jun 21 19:26:40 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c: prefer the use of relative branches so
        they won't need to be patched in aot code (patch from Patrick Beard).

Mon Jun 21 19:03:18 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * aot.c: patch from Patrick Beard to make the output assembly
        more correct for the MacOSX assembler. Small tweak to
        generate sane images on Linux/PPC, too.

Fri Jun 18 18:24:28 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c, mini.h, mini-ppc.c: handle varargs methods with a special
        case until bug #59509 is fixed (shows up in #60332).

Tue Jun 15 16:36:51 CEST 2004 Paolo Molaro <lupus@ximian.com>

        generate valid assembly for the Mach-O assembler.

Sun Jun 13 15:59:38 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * driver.c: don't include abcrem in the all optimization specifier
        since it slows down jit compilation too much for now.

2004-06-12 Ben Maurer  <bmaurer@users.sourceforge.net>

        * mini.c: use BIGMUL only if both operands have the same signage.
        * iltests.il: Test for bug 60056. (errors related to signage in

        statically glib as well.

Sat Jun 5 16:32:33 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * iltests.il, mini.c: fixed bug#59580 in branch optimization.

2004-06-03 Massimiliano Mantione <massi@ximian.com>
        * cpu-pentium.md basic-float.cs Fixed bug on fpu spills (see bug 54467),
        and added relevant test case.

Mon May 31 19:41:46 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c revert Zoltan's fix to bug#58863 on ppc, since it causes
        regressions in gtk-sharp.

2004-05-29  Zoltan Varga  <vargaz@freemail.hu>

        * exceptions.cs: New regression tests.

        * mini-sparc.h (MONO_ARCH_NEED_DIV_CHECK): Define this.

        * cpu-sparc.md mini-sparc.c: Add overflow detection to div opcodes.

2004-05-28      Patrik Torstensson <totte@hiddenpeaks.com>

        * mini.c (mono_jit_runtime_invoke): Init class in this
        method instead of trusting mono_jit_compile_method to
        do the work (because wrappers can be in object class)

2004-05-27  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c (mono_arch_output_basic_block): Fix sub.imm.

        libmono (track build dependencies).

2004-05-26  Zoltan Varga  <vargaz@freemail.hu>

        * cfold.c: Some glib versions do not have G_MININT32.

2004-05-26  Massimiliano Mantione  <massi@ximian.com>

        * mini-x86.c cpu-pentium.md Makefile.am basic-math.cs: Fixed problem
        with precision of tan, atan, sin and cos, and implemented related
        regressions tests (fixes bug 54467, but one new problem appeared and
        is not fixed yet).

2004-05-26  Zoltan Varga  <vargaz@freemail.hu>

        * cfold.c (FOLD_BINOPZ): Avoid division by zero.

        * exceptions.cs: Add test for constant folding && division by zero.

        * driver.c mini.h mini.c mini-x86.c: Revert most of the previous patch
        since driver.c is in libmono too, so the optimization was useless.

        * driver.c mini.h mini.c mini-x86.c: Moved the mono_lmf_addr TLS 
        variable to driver.c so the compiler can emit more efficient code to
        access them.

2004-05-26  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * Makefile.am: don't distribute generated inssel.[ch] files.

2004-05-25  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_jit_compile_method_with_opt): Really emit icall wrappers
        into the default appdomain. Fixes #58707.

        * jit-icalls.c: Remove the broken approximation for truncl, doing
        no conversion is better.

        * mini.c (handle_stack_args): Avoid reusing variables for stack slots.
        Fixes #58863.

Tue May 25 14:33:56 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ops.h, mini-ppc.c, cpu-g4.md, inssel-ppc.brg: eliminate the use
        of the mcrxr instruction which is not available on some processors
        even if it's documented to be. Implement add and sub overflow correctly
        (still not complete for long unsigned). Speed up icalls a bit.

2004-05-25 13:01 CET Patrik Torstenson <totte@hiddenpeaks.com>

        * mini.c (mono_jit_compile_method_with_opt): Make sure that
        we run .cctor in the current domain instead of target_domain.
        
        Fixes bug #58558, .cctor not being called in -O=shared.

Tue May 25 12:46:50 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.h, jit-icalls.c: added explicit checks for divide by zero.

2004-05-24 Ben Maurer  <bmaurer@users.sourceforge.net>

        * mini-x86.c (EMIT_COND_BRANCH): If an OP_LABEL has an offset
        which can be done with an imm8, do it that way.
        (mono_arch_output_basic_block): ditto for a jmp
        (mono_arch_emit_prolog): Computate maximum offset of a label.

2004-05-24 18:18 CET Patrik Torstenson <totte@hiddenpeaks.com>

        * mini-x86.c (mono_arch_local_regalloc): the reg allocator
        now tries to allocate prefered physical reg's for virtual

        Move some parts of the x86 exception handling code to an 
        arch-independent file so it can be shared with other ports.

Tue Apr 27 12:15:59 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * trace.c, cpu-g4.md, inssel-ppc.brg, mini-ppc.c: some fixes for FP code.

2004-04-26  David Waite  <mass@akuma.org>

        * driver.c: remove comma from end of enumeration declaration

2004-04-26  Jackson Harper  <jackson@ximian.com>

        * driver.c: parse config file before loading first assembly. This
        allows the user gac to be enabled/disabled. 
        
2004-04-23  Miguel de Icaza  <miguel@ximian.com>

        * mini-ppc.c (ppc_patch): Replaced the branch code patching with a
        simpler mechanism: we do not care what is encoded initially
        (branch absolute or relative), we care about the code and its
        target.  I kept the old code for reference for now.

        The new code tries first to determine if the jump is anywhere in
        the -/+32 absolute meg range, if it succeeds, it encodes using the
        absolute branch;  If not, it tried to find something in the
        relative range, if not, it uses the handle_thunk code. 

Fri Apr 23 14:20:40 EDT 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c, cpu-g4.md: made the branch macros more flexible.
        Raise exception on integer divide by zero by hand since the hw
        doesn't support it. Handle NaNs in FP compares.

Thu Apr 22 16:10:31 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * exceptions-ppc.c, mini-ppc.h, mini.c: simplified some
        code reducing duplication between the platforms and enabled
        signal exception handling (on linux for now).

Wed Apr 21 12:27:48 EDT 2004 Paolo Molaro <lupus@ximian.com>

        from exception clauses.

2004-04-18  Zoltan Varga  <vargaz@freemail.hu>

        * exceptions.cs (test_0_rethow_stacktrace): Make this work with
        inlining.

2004-04-18 Ben Maurer  <bmaurer@users.sourceforge.net>

        * iltests.il, basic.cs: more tests for regalloc.

        * exceptions-*.c (mono_arch_handle_exception): Do not overwrite the
        original stack trace if an exception is rethrown. Fixes #56782. Oh,
        the beauty of fixing the same thing in 5 different files...

2004-04-15  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_method_to_ir): Do not compute coverage for inlined
        methods.

        to init the context to setup the regs pointer).

Wed Apr 14 17:59:09 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * exceptions-ppc.c: more exceptions work.

Wed Apr 14 17:46:22 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c: avoid reusing the same MonoInst on multiple trees: this is
        not allowed.

2004-04-13  Miguel de Icaza  <miguel@ximian.com>

        * inssel-x86.brg (reg): Add new rules for add, sub and mul that

2004-04-13  Miguel de Icaza  <miguel@ximian.com>

        * mini-ppc.c: Remove unused definitions FLOAT_REGS and
        GENERAL_REGS they were also hardcoded for all PPC ports.

        (add_general): Use PPC_NUM_REG_ARGS instead of GENERAL_REGS.

        Remove hard-coded limit for floating point registers, use
        PPC_LAST_FPARG_REG instead in MONO_TYPE_R4 and MONO_TYPE_R8.

        Notice that in MacOS X calling conventions you can fit a lot more
        floating point values in registers, so I should update the PInvoke
        test to excercise the passing of floating point values on the
        stack (currently broken).
        
2004-04-06  Miguel de Icaza  <miguel@ximian.com>

        * tramp-ppc.c (create_trampoline_code): Added
        JUMP_TRAMPOLINE_SIZE. 
        (ppc_magic_trampoline): Follow the pattern from
        x86_magic_trampoline: if code is set to zero, return. 
        (create_trampoline_code): Always pass MonoMethod to the jump
        trampoline, before it was passing a null.
        (mono_arch_create_jump_trampoline): Implement the jump stub, could
        share the code with mono_arch_create_jit_trampoline.

        implemented.
        (mono_arch_patch_code): MONO_PATCH_INFO_METHOD_JUMP patch type

        already done.
        (mono_method_to_ir): Avoid freeing the type created returned from

        by the function. Fixes pointer.exe.

        * mini.c tramp-x86.c tramp-sparc.c tramp-ppc.c: Use the normal 
        trampolines for icalls and pinvokes as well. Fixes #33569.

        to g_module_symbol.
        - reworked the file format so it is now much smaller and needs
        fewer relocation entries.

        function so it can be reused. Inline also ctors if appropriate.

2003-04-28  Zoltan Varga  <vargaz@freemail.hu>

        * Makefile.am: Link with -export-dynamic so shared libs loaded by
        the runtime can call mono API functions.

2003-04-27  Martin Baulig  <martin@ximian.com>

        * debug-mini.c (mono_debug_init_method): Added
