[mono.git] / mono / mini / ChangeLog

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

        * iltests.il, mini.c: fixed bug#59580 in branch optimization.
        * exceptions.cs: make it compile with new mcs/csc.

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.

        * jit-icalls.c (mono_llmult_ovf): Fix some boundary conditions.

Sat May 29 10:45:58 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c: emit castclass/isinst in their own trees (bug #54209/59057).

2004-05-28  Zoltan Varga  <vargaz@freemail.hu>

        * 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.

        * basic-long.cs: New regression test.

Thu May 27 15:50:52 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * cpu-g4.md, mini-ppc.c: fixes to long add/sub ovf opcodes
        and div/rem checks.

Thu May 27 12:36:53 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * Makefile.am: fix miguel's change to build mono statically against
        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
        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
        the correct thing to do anyway (bug #58287).

2004-05-24  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c (mono_arch_flush_icache): Call sync_instruction_memory

2004-05-23  Zoltan Varga  <vargaz@freemail.hu>

        * ssa.c (mono_ssa_cprop): Allocate carray dynamically instead of on
        the stack.

2004-05-22  Zoltan Varga  <vargaz@freemail.hu>

        * 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.

        * mini.c: Add support for MARSHAL_CONV_FTN_DEL.
        
2004-05-21  Zoltan Varga  <vargaz@freemail.hu>

2004-05-20  Lluis Sanchez Gual  <lluis@ximian.com>

        * mini.c: Delegate most of the abort signal work to 
          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 
        supports the save/restore lmf opcodes.

2004-05-19  Zoltan Varga  <vargaz@freemail.hu>

        * mini-x86.c (mono_arch_setup_jit_tls_data): Handle code generated

        register too early on the chain.

2004-05-18  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (create_helper_signature): Use a helper function to reduce
        the code which needs to be written. Also set the calling convention of
        icalls on windows. Fixes #57840.

Tue May 18 11:05:18 CEST 2004 Paolo Molaro <lupus@ximian.com>

        order from the stack top (moved the stack room to save the
        return value for trace after the param area). Fixed corruption

Thu Apr 29 16:47:15 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c, cpu-g4.md: fixed unisgned -> double conversion.

        * mini-exceptions.c: New file.
        
        * mini.c mini-exceptions.c mini-x86.h exceptions-x86.c Makefile.am:
        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  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>

        * exceptions-ppc.c: use the correct ip register on macosx.

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

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

        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).

        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

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

        * mini.h mini.c aot.c: Modified the JIT so the generated AOT code is 
        no longer domain neutral. It can be made domain neutral by compiling 
        with --optimize=shared.

        callee method into the caller since one of them could be shared.

        * mini.h mini-x86.c aot.c: Added two new relocations so throwing
        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.

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

        * Makefile.am: Link with -export-dynamic so shared libs loaded by
