	only supported "sgen" and "llvm" config options and instead parse
	the MONO_ENV_OPTIONS as options that are parsed by the command

	* mini-trampolines.c mini.c: Rework the virtual call handling code by using a separate
	vtable trampoline for each vtable slot for both the LLVM and non-LLVM cases. Move
	most of the vcall specific code to mono_vcall_trampoline () from
	common_call_trampoline ().

2010-06-27  Zoltan Varga  <vargaz@gmail.com>

	* mini-trampolines.c (common_call_trampoline): Remove the code which created static
	rgctx trampolines when called from LLVM, they won't work for dynamic rgctx arguments
	if the callsite is patched.

	problem has been fixes.

2010-06-25  Zoltan Varga  <vargaz@gmail.com>

	* 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.

	instead.

2010-06-23  Miguel de Icaza  <miguel@novell.com>

	* 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  <rkumpera@novell.com>

	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-exceptions.c (mono_handle_exception_internal): Fix support for nested clauses
	in LLVM compiled code.

	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  <vargaz@gmail.com>

	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  <rkumpera@novell.com>

	* 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  <rkumpera@novell.com>

	This eliminates 2% of mono_value_copy calls on ipy and 12% on fsharp.

2010-06-17 Rodrigo Kumpera  <rkumpera@novell.com>

	* method-to-ir.c (mini_emit_stobj): Don't call mono_value_copy for small
	value types as the overhead is huge. 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  <vargaz@gmail.com>

	* mini-llvm.c (process_call): Disable LLVM for calls to generic class init

	exception trampolines.

	* tramp-x86.c: Add xdebug info for a few trampolines.

	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.

	* mini-amd64.c (get_call_info): Fix the handling of MONO_TYPE_TYPEDBYREF after

	* mini-posix.c: Move the old semantics from mini.c to the prototypes
	here for default implementations.
	* mini.c: Refactor mono_handle_native_sigsegv so that we can properly

	int_add_imm R12 <- R12 [1] clobbers: 1
	int_sub_imm R42 <- R12 [1] clobbers: 1

	The cprop pass would wrongly const prop + 1 to int_sub_imm which doesn't

	Fixes #505375.

2009-05-20  Andreia Gaita  <avidigal@novell.com>

	* Makefile.am: avoid going on the network just to get the revision,
	use git log instead

2009-05-19  Massimiliano Mantione  <massi@ximian.com>

	Fixed estimate for short branches on amd64 (they were off mark, and
	enabling call prolog-epilog instrumentations caused assertions).
	* mini.h (struct MonoBasicBlock): added max_length field to hold the
	estimate for the maximum length of this basic block.
	* mini-amd64.c:
	- mono_arch_emit_prolog: compute max_length for each basic block
	  (instead of max_offset), and inflate size estimate also for entry bb
	  in case of code instrumentation.
	- mono_arch_output_basic_block: get rid of "cpos" (the current
	  estimated "position" in the code), and always use "offset" instead,
	  which is accurate; at the beginning of the function quickly recompute
	  max_offset for all the remaining blocks, starting from the current
	  cfg->code_len (which is correct, and not estimated) and using the
	  estimated block lengths computed previously.

2009-05-17  Zoltan Varga  <vargaz@gmail.com>

	gshared use the static rgctx trampolines now.

	for ppc.

2009-05-15  Massimiliano Mantione  <massi@ximian.com>

	Made it possible for mono_arch_instrument_epilog to preserve
	argument registers, otherwise instrumenting the "epilogue" before
	a tail call would clobber them.
	* mini.h: Added "mono_arch_instrument_epilog_full" prototype, which
	if like mono_arch_instrument_epilog but with an additional parameter
	that states if argument registers must be preserved.
	* mini.c: implemented mono_arch_instrument_epilog as a call to
	mono_arch_instrument_epilog_full without asking to preserve argument
	registers (this makes the existing code work as usual).
	* mini-amd64.c:
	- 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

	the runtime and aot compiler are.
	
	* aot-compiler.c aot-runtime.c: Emit the got addr using a separate symbol,

2009-05-10  Miguel de Icaza  <miguel@novell.com>

	* aot-runtime.c (mono_aot_is_shared_got_patch): Move this routine

	case as well.

	* mini-arm.c: Implement OP_TLS_GET on arm eabi linux.
	
	* mini-arm.c (mono_arch_emit_prolog): Add an inlined version of

2009-01-23  Zoltan Varga  <vargaz@gmail.com>

	* aot-compiler.c aot-runtime.c: Treat delegate-invoke wrappers similarly to

	* mini-exceptions.c (ves_icall_get_frame_info): Fetch the generic
	info from the (correct) context.

	test was crashing due to that.

Fri Jan 16 15:21:21 CET 2009 Paolo Molaro <lupus@ximian.com>

	* exceptions-ppc.c: tweaks from malc (OV-Soft) to fix the size of the
	trampoline code. Include ucontext.h only if available.

2009-01-15  Mark Probst  <mark.probst@gmail.com>

	* mini.c: mono_domain_lookup_shared_generic() takes an open method
	and doesn't check whether it's sharable, like it was before

	performance back to what it was before that change.

2009-01-14  Mark Probst  <mark.probst@gmail.com>

	* 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

	* driver.c (mono_main): Revert r102623. The right
	thing to do is to enable the verifier under verifiable

	be verified under validil.

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

	* 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
	if no related --security flag is passed.

	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.

	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

	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:

	which will become
	     add ebx, 1

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

	* mini.c (CEE_LDSFLD): Make sure that the vtable has been init'd

	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.

	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.

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

	* Makefile.am (MCS,ILASM): Don't refer to runtime/ directory.

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

	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  <martin@localhost>

	* mini.c (mono_method_to_ir): Use `generic_container->context'
	rather than creating a new one.

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

2004-11-09  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.

	* 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.

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

	* 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>

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.

2004-10-25  Zoltan Varga  <vargaz@freemail.hu>

	* aot.c (mono_aot_load_method): Align PATCH_INFO_R8 on an 8 byte

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

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>

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

	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

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

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>

	(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

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

	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.
