Quentin Colombet	9729fb3315	[TwoAddressInstructionPass] Try 3 Addr Conversion After Commuting. TwoAddressInstructionPass stops after a successful commuting but 3 Addr conversion might be good for some cases. Consider: int foo(int a, int b) { return a + b; } Before this commit, we emit: addl %esi, %edi movl %edi, %eax ret After this commit, we try 3 Addr conversion: leal (%rsi,%rdi), %eax ret Patch by Volkan Keles <vkeles@apple.com>!

Charles Davis	e8f297ca94	Target/X86: Add explicit Win64 and System V/x86-64 calling conventions. Summary: This patch adds explicit calling convention types for the Win64 and System V/x86-64 ABIs. This allows code to override the default, and use the Win64 convention on a target that wants to use SysV (and vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU attributes.

NAKAMURA Takumi	1850c80afb	Target/X86: Tweak allocating shadow area (aka home) on Win64. It must be enough for caller to allocate one. llvm-svn: 124949	2011-02-05 15:11:32 +00:00

Andrew Trick	cf97db2402	reverting 116056: win64_params.ll may need to be conditionalized? llvm-svn: 116063	2010-10-08 17:22:42 +00:00
Cameron Esfahani	a07b5c291d	Small patch to restore home register stack space allocation for the Win64 case. Add test case. This code eventually needs to be tighter, since it's always allocating it, even in leaf routines. llvm-svn: 116056	2010-10-08 10:31:30 +00:00
