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!

Devang Patel 4a6e778aae Rename X86ATTAsmParser -> X86AsmParser
We are using one parser to parse att as well as intel style syntax.

Devang Patel 67bf992a8f Add definition for intel asm variant.
Right now, this just adds additional entries in match table. The parser does not use them yet.

Craig Topper f287a4509e Remove AVX hack in X86Subtarget. AVX/AVX2 are now treated as an SSE level. Predicate functions have been altered to maintain previous names and behavior.

Craig Topper a5d1fc2cc7 Make FMA4 imply AVX so that YMM registers would be available. Necessitates removing from Bulldozer CPU types since it would enable AVX code generation implicitly. Also make SSE4A imply SSE3. Without some level of SSE implied, XMM registers wouldn't be legal.

2011-12-30 07:16:00 +00:00
Craig Topper e1bd05128e Make FMA3 imply AVX needs to be enabled. Particularly because 256-bit types aren't valid unless AVX is enabled.

Nate Begeman 8b08f5232b Formalize the notion that AVX and SSE are non-overlapping extensions from the compiler's point of view. Per email discussion, we either want to always use VEX-prefixed instructions or never use them, and are taking "HasAVX" to mean "Always use VEX". Passing -mattr=-avx,+sse42 should serve to restore legacy SSE support when desirable.

Jim Grosbach c6e13f7383 Clean up asm writer usage for x86 and msp430 to flag that the writer should
use MC instructions in the printInstruction() method via the tablegen flag

Daniel Dunbar 9b816a1bb3 MC/X86: Add "support" for matching ATT style mnemonic prefixes.
- The idea is that when a match fails, we just try to match each of +'b', +'w',
   +'l'. If exactly one matches, we assume this is a mnemonic prefix and accept
   it. If all match, we assume it is width generic, and take the 'l' form.

 - This would be a horrible hack, if it weren't so simple. Therefore it is an
   elegant solution! Chris gets the credit for this particular elegant
   solution. :)

 - Next step to making this more robust is to have the X86 matcher generate the
   mnemonic prefix information. Ideally we would also compute up-front exactly
   which mnemonic to attempt to match, but this may require more custom code in
   the matcher than is really worth it.

Jakob Stoklund Olesen b93331f3be Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field.
When a target instruction wants to set target-specific flags, it should simply
set bits in the TSFlags bit vector defined in the Instruction TableGen class.

This works well because TableGen resolves member references late:

class I : Instruction {
  AddrMode AM = AddrModeNone;
  let TSFlags{3-0} = AM.Value;
}

let AM = AddrMode4 in
def ADD : I;

TSFlags gets the expected bits from AddrMode4 in this example.

Eric Christopher 2ef63183a5 Separate out the AES-NI instructions from the SSE4.2 instructions. Add
a new subtarget option for AES and check for the support.  Add "westmere"
line of processors and add AES-NI support to the core i7.

Add a couple of TODOs for information I couldn't verify.
