2010-06-26 Zoltan Varga * mini-llvm.c: Fix a few problems exposed by make check. 2010-06-25 Mark Probst * mini-trampolines.c (common_call_trampoline): An ugly hack to work around a potentially very hard to fix problem with inflating generic methods. 2010-06-26 Zoltan Varga * method-to-ir.c (mono_emit_wb_aware_memcpy): Remove the workaround as the core problem has been fixes. 2010-06-25 Zoltan Varga * Makefile.am: Add an 'SGEN' make variable to allow tests to be run with SGEN. * mini-gc.c (mini_gc_init_cfg): Use mono_gc_is_moving () instead of HAVE_SGEN_GC. It might be be better to define a MonoGCJitOptions structure later and have the GC return that. * mini-darwin.c: Don't undefine pthread_ calls for SGEN, they are no longer defined. * Makefile.am: Use libwapi.la for both sgen and non-sgen builds. * debugger-agent.c (get_objref): Implement support for sgen. * driver.c: Remove the unused gc_wrapper.h include. * driver.c (mono_main): Delegate the --desktop mode optimizations to the GC implementation. 2010-06-25 Zoltan Varga * driver.c (mono_main): Use mono_gc_get_description () to print the GC name. * mini-gc.c (mini_gc_init_cfg): New function to initialize GC specific flags in MonoCompile. * method-to-ir.c mini.c: Remove usage of HAVE_SGEN_GC and use runtime checks instead. 2010-06-23 Miguel de Icaza * Makefile.am: Build the mono-sgen binary a Mono VM with the Sgen GC enabled as well as libmono-sgen-2.0 and libomonosgen-static * driver.c: Do not depend on the USED_GC_NAME when using SGen, use it only for Boehm diagnostics. * Makefile.am: Make the file a bit more consistent. * debug-debugger.c: Wrap the entire file with an #ifdef MONO_DEBUGGER_SUPPORTED to simplify the build. * Makefile.am: Fix the opcodes build issue by including the source, not by including the .lo file directly Always bring the MDB sources into the build, to drop the dependency on the AM_CONDITIONAL from configure.in as the hard debugger supports Boehm, but not Sgen, this simplifies the build. * Renamed the *.s files into *.S 2010-06-24 Rodrigo Kumpera * method-to-ir.c (mono_emit_wb_aware_memcpy): Don't emit bitmap wb for now on 64bits systems while issues with valuetype returns are not fixed. 2010-06-24 Zoltan Varga * mini-llvm-cpp.cpp (mono_llvm_create_ee): Add support for using a standard set of passes by calling createStandardFunctionPasses (). 2010-06-23 Zoltan Varga * mini.h (MONO_INS_HAS_NO_SIDE_EFFECT): Add OP_LDADDR. 2010-06-22 Zoltan Varga * method-to-ir.c (mono_method_to_ir): Don't mark loads from OP_LDADDR with MONO_INST_FAULT. * mini-llvm.c (mono_llvm_emit_method): Recalculate MONO_INST_INDIRECT flags to allow better optimization if the OP_LDADDR which caused the flag to be set was optimized away. * exceptions-amd64.c (get_throw_trampoline): Align the stack properly. * mini-amd64.c (mono_arch_emit_exceptions): Pass only the type token index, not the type token. * mini-llvm.c (emit_entry_bb): Save the this argument only in gshared methods. * mini-llvm.c: Fix a couple memory leaks. Get rid of a few #ifdefs. 2010-06-22 Zoltan Varga * tramp-amd64.c (mono_arch_nullify_class_init_trampoline): Call patch_callsite () to handle the code sequence generated for non-near calls.

(mono_llvm_check_method_supported): Enable llvm for methods with nested clauses. (mono_llvm_emit_method): Instead of calling 'mono_resume_unwind' directly, call a trampoline which saves the context, so changes made to callee saved registers in finally clauses are visible to a nesting catch clause. * exceptions-amd64.c: Add a resume_unwind trampoline for LLVM. * mini-exceptions.c (mono_handle_exception_internal): Fix support for nested clauses in LLVM compiled code. (mono_handle_exception_internal): Add a 'ctx' argument containing the state after the finally handler has ran. * mini.h (ResumeState): New structure containing information required to resume exception handling after executing LLVM compiled finally clauses. * exceptions-amd64.c (get_throw_trampoline): Clean up the amd64 throw trampolines a bit, by passing all the registers as one argument. 2010-06-19 Zoltan Varga * tramp-amd64.c (mono_arch_create_generic_trampoline): Increase the buf len a little, to avoid an assert. 2010-06-18 Zoltan Varga * aot-compiler.c (emit_klass_info): Mark unloadable classes properly. * aot-compiler.c aot-runtime.c: Fix LLVM support. * mini-llvm.c: When emitting OP_CALL_HANDLER, avoid branching directly to the landing pad, branch to a new bblock instead. * aot-compiler.c (emit_method_code): Use cfg->header instead of the header of orig_method. * exceptions-amd64.c (mono_arch_exceptions_init): Fix fullaot support. * mini-llvm.c (process_bb): Add support for OP_SQRT when using the LLVM mono branch. 2010-06-17 Geoff Norton * mini-arm.h: * exceptions-arm.c: Move the UCONTEXT macros to mono-sigcontext.h so they can be used by sgen. 2010-06-17 Zoltan Varga * aot-compiler.c (emit_klass_info): Handle type load exceptions. * method-to-ir.c (mono_method_to_ir): Avoid a crash if mono_method_get_header () fails. * exceptions-x86.c (mono_x86_throw_corlib_exception): Negate the decrement of the ip done by throw_exception (), it is not needed for corlib exceptions. 2010-06-17 Rodrigo Kumpera * method-to-ir.c (mono_emit_wb_aware_memcpy): Simplify this function. Call new jit icall mono_gc_wbarrier_value_copy_bitmap for vt wbarrier of size > 5 words. This support fast barriers for value types up to 256/512 bytes which beyond that the copying itself is the major issue. * method-to-ir.c (mini_emit_stobj): The intrinsic version is safe for gsharing, so use it. This eliminate all calls to mono_value_copy from managed code in gmcs, fsharp and ipy. This gives a 2% perf boost on ipy and 1% on gmcs over previous patches. Even thou a lot of mono_value_copy calls were eliminated from fsharp, performance kept * mini.c (mini_init): Register new icall. 2010-06-17 Rodrigo Kumpera * method-to-ir.c (mono_emit_wb_aware_memcpy): Handle nested valuetypes.

Manually expand it up to 5 words to avoid code bloat. This improves gmcs times by 5% and unmodified binary-tree by 78%. The later is an exception that performance is dominated by mono_value_copy. This puts sgen about 5% ahead of boehm in terms of wall-clock on a Core2Quad. 2010-06-17 Zoltan Varga * mini-llvm.c (process_call): Disable LLVM for calls to generic class init trampolines on x86, since those have their own cconv. * exceptions-x86.c (mono_arch_exceptions_init): Implement the llvm throw corlib exception trampolines. * tramp-x86.c: Add xdebug info for a few trampolines. * mini-llvm.c: Set the name of the arguments. * mini-llvm.c (emit_cond_system_exception): Pass the ip of to throw_corlib_trampoline using a block address if using the LLVM mono branch. * exceptions-amd64.c (mono_arch_exceptions_init): Add new LLVM throw corlib exception trampolines. 2010-06-15 Zoltan Varga * mini-ppc.c (mono_arch_get_cie_program): Define this for powerpc too. * mini-llvm.c (process_bb): Add a missing CHECK_FAILURE. * mini.c (mini_init): Remove some of the llvm restrictions, they are no longer needed. * method-to-ir.c (mono_method_to_ir): Enable fast virtual calls when using llvm. * mini-trampolines.c (mono_llvm_vcall_trampoline): Rewrite this to use one vtable trampoline per vtable slot index. The slot, along with the 'this' argument is enough to identify the vtable slot address plus the method which needs to be compiled. * mini.c (mini_get_vtable_trampoline): Use one vtable trampoline per vtable slot when using llvm. * mini-x86.c (get_call_info_internal): Change the managed calling convention so 'this' is always passed as the first argument, before the vtype ret arg.

This simplifies get_this_arg_reg () and LLVM integration. 2010-06-14 Rodrigo Kumpera * method-to-ir.c (mono_method_to_ir): Add support for .ctor intrinsics. * method-to-ir.c (mini_emit_inst_for_ctor): New function for .ctor intrinsics. For now just call simd intrinsics. This makes "x[0] = new Vector4f (10)" translate into much nicer code. 2010-06-14 Zoltan Varga * mini-llvm.c (sig_to_llvm_sig_full): Add a 'sinfo' out argument which returns parameter index information. Use this to simplify a lot of code. * unwind.c (mono_unwind_decode_fde): Handle augmentions using a loop. 2010-06-12 Zoltan Varga * aot-compiler.c (compile_method): Add a 'depth' parameter to add_generic_class too to fix infinite generic recursion.

mono_arch_instrument_epilog: add parameter to transform it into mono_arch_instrument_epilog_full, and preserve argument registers when required. - mono_arch_output_basic_block, OP_TAILCALL case: call mono_arch_instrument_epilog_full. * mini-alpha.c, mini-arm.c, mini-hppa.c, mini-ia64.c, mini-mips.c, mini-ppc.c, mini-s390.c, mini-s390x.c, mini-sparc.c, mini-x86.c: only transformed mono_arch_instrument_epilog into mono_arch_instrument_epilog_full. 2009-05-15 Geoff Norton * mini-darwin.c: This works on arm now. 2009-05-14 Geoff Norton * jit.h, driver.c: Allow full-aot to be decided programatically by the embedding api. 2009-05-15 Zoltan Varga * aot-compiler.c (emit_method_code): Skip a few more characters in the debug label names. * mini-trampolines.c (mono_magic_trampoline): Handle static rgctx invoke wrappers during full aot mode correctly. * aot-runtime.c (mono_aot_get_unbox_trampoline): Handle shared generic methods correctly. * aot-compiler.c (mono_aot_method_hash): Use our internal version of mono_metadata_type_hash (). 2009-05-14 Massimiliano Mantione * mini.h, mini-codegen.c, mini-alpha.c, mini-amd64.c, mini-arm.c, mini-hppa.h, mini-hppa.c, mini-ia64.c, mini-mips.h, mini-mips.c, mini-ppc.c, mini-s390.c, mini-s390x.c, mini-sparc.c, mini-886.c: Removed MONO_INST_BRLABEL from the instruction flags, and the remaining code that used it, because we do not support branches inside basic blocks (and branch target labels) anymore. * Makefile.am: As part of the above cleanup, remove reference to BURG files which don't exist anymore. 2009-05-14 Zoltan Varga * image-writer.c (asm_writer_emit_local_symbol): Make this a nop on osx. * mini-mips.c mini-mips.h exceptions-mips.c: Transition the mips backend to use mono_arch_throw_corlib_exception. * mini-ppc.c mini-ppc.h exceptions-ppc.c: Use mono_arch_throw_corlib_exception for throwing corlib exceptions. * aot-runtime.c (decode_patch): Allocate the data for R4/R8 from the domain mempool. * mini.c (mono_patch_info_dup_mp): Copy the table of switch targets too. * aot-compiler.c: Emit a local symbol prefixed with the assembly name for the got to make debugging easier and to avoid confusing it with the system got. * aot-compiler.c (emit_method_code): Emit a C style symbol for each method so a breakpoint can be set when using gdb. 2009-05-13 Zoltan Varga * aot-compiler.c (mono_aot_method_hash): Implement this properly based on mono_method_get_imt_slot (). * aot-runtime.c (find_extra_method_in_amodule): Get rid of the num_decodes variables. * aot-compiler.c (mono_aot_method_hash): Revert part of the last change as it doesn't seem to work. * aot-compiler.c (mono_aot_method_hash): Improve the hashing of wrappers. 2009-05-12 Zoltan Varga * aot-compiler.c mini.c mini-amd64.h mini-arm.h: Kill MONO_ARCH_FULL_AOT_IMT_SUPPORTED define, both platforms now support imt. * mini.c (mini_init): Install mono_aot_get_imt_thunk as the IMT thunk builder when using full aot. * mini-amd64.c (mono_arch_build_imt_thunk): Don't handle the full-aot case here, it is already handled. * mini-arm.c (mono_arch_emit_imt_argument): Pass the dynamic imt arg correctly for IMT. * aot-compiler.c (arch_emit_imt_thunk): Implement this for ARM. * mini-arm.h: Enable IMT for full aot. * aot-compiler.c (mono_compile_assembly): Don't emit imt thunk if the arch doesn't support it. * mini.c (mini_init): Don't disable IMT for full aot if the architecture supports it. * mini.h (MonoAotTrampoline): New enum containing the different types of 'numerous' trampolines.

Fixes #431413. 2008-10-01 Mark Probst * method-to-ir.c: When generic sharing is active, call non-interface virtual generic methods via the standard trampoline. * mini-trampolines.c: Handle virtual generic shared methods. * mini.h, mini-x86.c, mini-x86.h: New argument for mono_arch_build_imt_thunk() which is non-NULL for virtual generic method thunks and which is the trampoline to call if the lookup fails.

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. 2008-05-06 Martin Baulig Fix #383749. * debug-mini.c (mono_debugger_thread_created): Add proper locking. (mono_debugger_thread_cleanup): Likewise.

Fixes gen-112.cs. 2004-11-28 Martin Baulig * 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 * mini.c (mono_method_to_ir): Use `!method->signature->has_type_parameters' in the g_assert(). 2004-11-26 Zoltan Varga * mini-amd64.c (mono_arch_emit_this_vret_args): Handle this and vret 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 * Makefile.am: Consistently use $(RUNTIME) rather than ./mono to pick up in-tree mscorlib.dll. 2004-11-25 Zoltan Varga * 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. * tramp-amd64.c (amd64_magic_trampoline): Patch RIP relative calls too. * inssel.brg (SWITCH): Emit an AOT_CONST in the aot case. * mini-amd64.h: Turn on PIC AOT code. * 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 * mini.c (mono_method_to_ir): In CEE_CALL, don't allow calling any uninflated generic methods. 2004-11-25 Martin Baulig * mini.c (mono_method_to_ir): Don't allow any uninflated generic methods. 2004-11-24 Martin Baulig * 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 * 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 * 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 * mini-amd64.c (mono_arch_output_basic_block): Set %al to the number of used SSE registers on pinvoke calls.

(mini_init): Get rid of it from here too. Thu Nov 11 20:17:17 CET 2004 Paolo Molaro * mini-ppc.c, mini-ppc,h, cpu-g5.md, exceptions-ppc.c: implemented OP_RETHROW (patch by Geoff Norton ). 2004-11-10 Geoff Norton * tramp-ppc.c (ppc_magic_trampoline): Don't trampoline methods between appdomains. Fixes appdomain-unload on PPC. 2004-10-26 Lluis Sanchez Gual * exceptions-ppc.c, exceptions-s390.c, exceptions-s390x.c, mini-exceptions.c: handle the new wrapper types. * mini.c: The CEE_ISINST and CEE_CASTCLASS opcodes now take the 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 * mini.c (mono_method_to_ir): Use `generic_container->context' rather than creating a new one. 2004-11-09 Neale Ferguson * exceptions-s390.c, mini-s390, cpu-s390.md: Add support for OP_RETHROW. * inssel-390.md, mini-s390.c: Correct register allocation for globals. 2004-11-09 Zoltan Varga * aot.c (mono_aot_init): Add MONO_AOT_CACHE env variable to turn on the experimental aot cache stuff.

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.

Use stb/sth for the former, and put the latter always on stack instead of in argument registers. 2004-10-30 Zoltan Varga * trace.c (is_filenamechar): Add '_'. 2004-10-29 Neale Ferguson * mini-s390.c: Fix prolog length to allow for large trace requirements. * exceptions-s390.c: Remove dwarf unwinding stuff that was unused. 2004-10-29 Zoltan Varga * Makefile.am (libgc_libs): Do some automake magic so libmono/mono depends on libmonogc. Fixes #68805. 2004-10-26 Miguel de Icaza * mini.c (mono_jit_free_method): Provide extra information for this error.

Fix warnings. * 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 * driver.c: Add SHARED to the set of optimizations tested. * tramp-amd64.c (amd64_magic_trampoline): Patch trampoline code as well. * mini.c (mono_method_to_ir): Mark the domainvar as volatile when it is implicitly used by CEE_NEWARR. * ssa.c (mono_ssa_deadce): Do not optimize away accesses to volatile variables. 2004-10-20 Martin Baulig * mini-exceptions.c (mono_handle_exception): Call mono_debugger_handle_exception() to tell the debugger about catch/finally clauses. 2004-10-18 Zoltan Varga * exceptions-amd64.c (mono_arch_find_jit_info): Pop arguments of the stack. * mini-amd64.c (mono_amd64_get_vcall_slot_addr): Handle extended registers. Fixes #68447. 2004-10-15 Geoff Norton * 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 * trace.c (mono_trace_eval): Use mono_method_desc_full_match. Fixes #68388. 2004-10-11 Martin Baulig * mini.c (mono_method_to_ir): If we're a generic method, get the MonoGenericContainer from our MonoMethodNormal and create a MonoGenericContext from it. 2004-10-08 Zoltan Varga * inssel-long32.brg (OP_LCONV_TO_OVF_I2): Fix CONV_I1 -> CONV_I2. * basic-long.cs: Add test for checked i8->i2 cast.

Add rules for SAVE_LMF and RESTORE_LMF. 2004-07-06 Ben Maurer * 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.

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 * 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 May 3 22:58:51 CEST 2004 Paolo Molaro * inssel-ppc.brg: another small pre-release workaround: we don't do overflow detection for long_sub_un. Sun May 2 20:12:22 CEST 2004 Paolo Molaro * mini.c, mini-ops, inssel-long32.brg: speedup ulong >> 32 (also works around a weird ppc bug: 57957). Sat May 1 16:56:10 EDT 2004 Paolo Molaro * tramp-ppc.c: trampoline fixes. Fri Apr 30 15:54:26 EDT 2004 Paolo Molaro * mini-ppc.c: fixed typos. Thu Apr 29 20:15:41 CEST 2004 Paolo Molaro * mini-ppc.c, exceptions-ppc.c: more code saves registers at the top of the stack. Fixed typos. Use a frame registers for all the methods with exception clauses. Thu Apr 29 18:52:09 CEST 2004 Paolo Molaro * exceptions-ppc.c: restore fp registers. Thu Apr 29 18:26:56 CEST 2004 Paolo Molaro * mini-ppc.c, exceptions-ppc.c: save the registers in reverse order from the stack top (moved the stack room to save the return value for trace after the param area).

This allows the user gac to be enabled/disabled. 2004-04-23 Miguel de Icaza * 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 * exceptions-ppc.c: use the correct ip register on macosx. Thu Apr 22 13:23:16 EDT 2004 Paolo Molaro * exceptions.c, mini.c, mini-ppc.h: adapt code to macosx.

Wed Apr 14 17:59:09 CEST 2004 Paolo Molaro * exceptions-ppc.c: more exceptions work. Wed Apr 14 17:46:22 CEST 2004 Paolo Molaro * mini.c: avoid reusing the same MonoInst on multiple trees: this is not allowed. 2004-04-13 Miguel de Icaza * inssel-x86.brg (reg): Add new rules for add, sub and mul that can use the memory directly. * cpu-pentium.md: Update documentation from a post from Zoltan. add x86_add_membase, x86_sub_membase, x86_mul_membase 2004-04-13 Miguel de Icaza * 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 * 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. * mini-ppc.c (mono_arch_output_basic_block): CEE_JMP opcode implemented. (mono_arch_patch_code): MONO_PATCH_INFO_METHOD_JUMP patch type implemented. * cpu-g4.md: Added length for jmp instruction, the worst case scenario is 92 bytes (4 mandatory bytes, potential 19 registers for save_lmf). 2004-04-08 Zoltan Varga * aot.c (mono_compile_assembly): Add back unlink removed by mistake. 2004-04-07 Zoltan Varga * mini.c: Only set bblock->real_offset when adding a new bblock, and before each IL instruction. * mini.c (CEE_BOX): Fix warnings. 2004-04-07 Gonzalo Paniagua Javier * mini.c: removed a few unused vars and extra whitespace. 2004-04-05 Ben Maurer * inssel.brg (MONO_EMIT_BOUNDS_CHECK): a new macro to emit bounds checks.

(mono_method_to_ir): Added `constrained_call' variable. (mono_method_to_ir:CEE_CONSTRAINED_): Set it. (mono_method_to_ir:CEE_CALL): If `constrained_call' is set, use mono_method_get_constrained() to get the method. 2004-04-01 Martin Baulig * mini.c (TYPE_PARAM_TO_TYPE, TYPE_PARAM_TO_CLASS): Removed. (MTYPE_PARAM_TO_TYPE, MTYPE_PARAM_TO_CLASS): Removed. (mono_method_to_ir): We don't need these macros anymore since mono_class_get_full() already takes care of it. 2004-03-31 Gonzalo Paniagua Javier * aot.c: set aot_verbose to 0, fixed format string that caused sigsegv, use @function (as doesn't accept #function here) and check the return value of system and stop if fails. 2004-03-31 Gonzalo Paniagua Javier * mini.c: set the timeout to 2s when calling mono_domain_finalize. 2004-03-31 Zoltan Varga * mini-ppc.c (mono_arch_patch_code): Fix ppc build. * inssel-sparc.brg mini-sparc.c aot.c: Implement AOT support. * inssel-long32.brg (OP_LNEG): Use ADC instead of ADD here.

Thanks to Willibard Krenn for spotting this. Also remove unused conv_u4 opcode. * mini-x86.c: Remove valgrind workaround since it slows down things even when mono is not run under valgrind. 2004-03-26 Zoltan Varga * mini-sparc.c: Update status. * inssel-sparc.brg: Add some optimizations. * inssel-sparc.brg mini-sparc.c: Rework branch instructions to allow future delay slot filling. Add support for varargs, tail calls and JMP. * inssel.brg mini-ops.h mini.c: Use OP_REFANYTYPE instead of CEE_REFANYTYPE, since CEE_REFANYTYPE needs a prefix to be unique. * inssel.brg: Fix register allocation in OP_ARGLIST. * inssel.brg: Fix warnings. 2004-03-25 Martin Baulig * mini.c (inflate_generic_field): Removed.

(mini_get_method): Take a `MonoGenericContext *' instead of a `MonoMethod *'. (TYPE_PARAM_TO_TYPE, MTYPE_PARAM_TO_TYPE): mono_method_to_ir() has a new local variable called `generic_context' which holds the current `MonoGenericContext *'; use it to lookup things. 2004-03-24 Martin Baulig * mini.c (mini_get_class): New static method; if we're inside a generic instance, inflate the class if neccessary. (mono_method_to_ir): Use mini_get_class() instead of mono_class_get(). 2004-03-24 Zoltan Varga * iltests.il: New regression test for #55976. * mini.c (mono_method_to_ir): Empty the stack in endfinally.
