        are gathered. Run with: MONO_RTC=4096 mono --profiler=default:stat ....
        The MONO_RTC value must be restricted to what the linux rtc allows:

        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

        * 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

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.

        * 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>

        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).

        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

        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

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).

        * aot.c (load_aot_module): Move reading of got_addr after the AOT
        file version check.
        
2004-12-14  Patrik Torstensson  <patrik.torstensson@gmail.com>

        * 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>

        again. `patch_info->table_size' is no longer valid after Zoltan's
        commit #37636.

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

        * 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

        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.

2004-11-30  Martin Baulig  <martin@ximian.com>

        * 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>

        platforms with PIC aot.

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

        * mini.c (mono_method_to_ir): In CEE_DUP, added handle_stobj().
        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'

        the same way as the other arguments so they won't get clobbered.

        * 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.

2004-11-25  Zoltan Varga  <vargaz@freemail.hu>

        * 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
        symbols.

        * mini.h (mono_arch_get_aot_patch_offset): New arch specific function
        returning the offset within an OP_AOTCONST instruction where the GOT
        offset needs to be added.

        * mini.h: Bump AOT file format version.

2004-11-25  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): In CEE_CALL, don't allow calling any
        uninflated generic methods.

2004-11-25  Martin Baulig  <martin@ximian.com>

        * 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.

        * iltests.il (test_0_localloc_inline): Add regression test for #69678.
        
2004-11-23  Zoltan Varga  <vargaz@freemail.hu>

        * mini-amd64.c (mono_arch_output_basic_block): Set %al to the number of
        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.
        Check if a trampoline for a synchronized method is required. 

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>

        * mini-ppc.c: Call mono_type_get_underlying_type to unwrap generic
        types before switching on type.  Fixes #69622.

2004-11-19  Raja R Harinath  <rharinath@novell.com>

        * Makefile.am (check-local): New.  Integrate into 'make check'.
        (MCS,RUNTIME): Define using in-tree mono and mcs.
        (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
        #69664.

2004-11-17  Raja R Harinath  <rharinath@novell.com>

        * Makefile.am (clean-local): Rename from 'clean'.

2004-11-15  Nelae Ferguson <Neale.Ferguson@SoftwareAG-usa.com>

        * mini.c, mini-x86.c, mini-amd64.c, exceptions-s390.c: Add siginfo_t parameter

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>

        * mini-ppc.c, mini-ppc,h, cpu-g5.md, exceptions-ppc.c:
        implemented OP_RETHROW (patch by Geoff Norton
        <gnorton@customerdna.com>).

2004-11-10  Geoff Norton  <gnorton@customerdna.com>

        * tramp-ppc.c (ppc_magic_trampoline): Don't trampoline methods
        between appdomains.  Fixes appdomain-unload on PPC.

        token value as a MonoClass* when compiling a wrapper.
        mono_jit_create_remoting_trampoline now takes an additional
        MonoRemotingTarget parameter.
        
2004-11-10  Martin Baulig  <martin@localhost>

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

        * inssel-390.md, mini-s390.c: Correct register allocation for globals.

2004-11-09  Zoltan Varga  <vargaz@freemail.hu>

        * aot.c (mono_aot_init): Add MONO_AOT_CACHE env variable to turn on
        the experimental aot cache stuff.

Tue Nov 9 17:30:20 CET 2004 Paolo Molaro <lupus@ximian.com>

        * aot.c, mini.c, exceptions-ppc.c, exceptions-s390.c, exceptions-s390x.c,
        mini-exceptions.c: update to exception clause structure changes.

2004-11-08  Zoltan Varga  <vargaz@freemail.hu>

        * exceptions-x86.c (throw_exception): Fix warnings.

        * mini-x86.h mini-x86.c cpu-pentium.md exceptions-x86.c: Add support 
        for OP_RETHROW.

2004-11-08  Zoltan Varga  <vargaz@freemail.hu>

        * exceptions-sparc.c (get_throw_exception): Really fix this.

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.

        * mini-sparc.h mini-sparc.c exceptions-sparc.c: Add support for OP_RETHROW.

        * mini.h: Add mono_arch_get_rethrow_exception () arch specific function.
        * mini-ops.h: Add OP_RETHROW.

2004-11-05  Geoff Norton  <gnorton@customerdna.com>
        
        * helpers.c: Change otool arguments from -V -v -t to -v -t on Darwin
        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.

2004-11-05  Zoltan Varga  <vargaz@freemail.hu>

        * tramp-sparc.c (mono_arch_create_jit_trampoline): Fix sparc build.

        into a new function mono_create_jit_trampoline ().

2004-11-02  Zoltan Varga  <vargaz@freemail.hu>

        * trace.c (get_spec): Allow tracing of classes without a namespace.

2004-11-02  Sebastien Pouliot  <sebastien@ximian.com>

        * mini.c: Fix pointer overwrite in mini_method_compile.

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

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

        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

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

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.

        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

        * 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.

        * 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>

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.

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

        (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
        regs. This reduces the number of emited spills/loads with
        20-30% on our core assemblies.

Mon May 24 18:21:51 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * jit-icalls.c: truncl() is not needed and trunc() is

        * mini-sparc.c (mono_arch_output_basic_block): ADD_IMM and SUB_IMM
        should set carry.

        * basic-long.cs: Add tests for add/subtract of immediates with carry.

        * mini.c exceptions-x86.c: Remove MONO_USE_EXC_TABLES stuff.
        
        * mini.c (inline_method): Allways inline some wrappers even if the cost
        is too large. Fixes #58785.

          mono_thread_request_interruption, which also handles Stop and Suspend
          states.

2004-05-20  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c mini.h: Allow inlining of icall wrappers if the backend

        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>

        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

        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.

2004-04-14  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c: Add support for STRWLPARRAY marshalling convention.

Wed Apr 14 18:15:55 CEST 2004 Paolo Molaro <lupus@ximian.com>

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

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).

        trampoline, before it was passing a null.
        (mono_arch_create_jump_trampoline): Implement the jump stub, could

        a new local variable called `generic_context' which holds the
        current `MonoGenericContext *'; use it to lookup things.

2004-03-24  Martin Baulig  <martin@ximian.com>

        * mini.c (mini_get_class): New static method; if we're inside a
        generic instance, inflate the class if neccessary.

        system exceptions from AOT code now works.

        * tramp-x86.c (x86_magic_trampoline): Avoid patching the calling 
        method if it is domain neutral and the callee is not.
