Andrew Trick	8523b16ff5	Instruction scheduling itinerary for Intel Atom. Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT. Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches. Adds a test to verify that the scheduler is working. Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP. Patch by Preston Gurd! llvm-svn: 149558	2012-02-01 23:20:51 +00:00
NAKAMURA Takumi	4c14a5cc2c	Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 generally. No one uses *-mingw64. mingw-w64 is represented as {i686\|x86_64}-w64-mingw32. In llvm side, i686 and x64 can be treated as similar way. llvm-svn: 125747	2011-02-17 12:24:17 +00:00
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
Duncan Sands	ebf838274f	Correct some bogus target triples. llvm-svn: 103265	2010-05-07 17:03:48 +00:00
Dan Gohman	40503396da	Eliminate more uses of llvm-as and llvm-dis. llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Dan Gohman	0d4bbf2c4a	Remove obsolete -f flags. llvm-svn: 79992	2009-08-25 15:38:29 +00:00
Anton Korobeynikov	71386e08fe	Unbreak Win64 CC. Step one: honour register save area, fix some alignment and provide a different set of call-clobberred registers. llvm-svn: 77962	2009-08-03 08:12:53 +00:00
Eli Friedman	63488f1fbf	PR3739, part 2: Use an explicit store to spill XMM registers. (Previously, the code tried to use "push", which doesn't exist for XMM registers.) llvm-svn: 72836	2009-06-04 02:32:04 +00:00
