	* 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

	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

	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

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.

2004-11-19  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.

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

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

	* 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

	(mono_aot_load_method): Do not allocate MonoAotMethod in the GC heap.

2004-10-24  Zoltan Varga  <vargaz@freemail.hu>

	* mini-amd64.c (mono_arch_patch_code): Fix patching of class init

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>

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.

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

	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

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

	* 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>

	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

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 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.
