Jakob Stoklund Olesen 42caaa4f5b Switch SSEDomainFix to SpecificBumpPtrAllocator.

Chris Lattner d20699bc87 Momentous day: remove the "O" member from AsmPrinter. Now all 
"asm printering" happens through MCStreamer.  This also 
Streamerizes PIC16 debug info, which escaped my attention.

This removes a leak from LLVMTargetMachine of the 'legacy'
output stream.

 2010-04-04 08:18:47 +00:00
Chris Lattner d479317d65 streamerize printing of dbg_value, the x86 backend is now fully 
streamerized for everything.

Chris Lattner 9b13639f45 mc'ize elf stub printing, convert cygwin stuff to EmitRawText, 
which will abort in .o file writing mode.

Chris Lattner 3bb09768cb fix PrintAsmOperand and PrintAsmMemoryOperand to pass down 
raw_ostream to print to.

 2010-04-04 05:29:35 +00:00
Chris Lattner 787253819a use predicates in DBG_VALUE printing code to simplify it.

Chris Lattner 562e02e4e1 remove more implicit uses of "O". 
llvm-svn: 100311
 2010-04-04 05:19:20 +00:00
Chris Lattner 7012916275 fix an ugly wart in the MCInstPrinter api where the 
raw_ostream to print an instruction to had to be specified
at MCInstPrinter construction time instead of being able
to pick at each call to printInstruction.

llvm-svn: 100307
 2010-04-04 05:04:31 +00:00
Chris Lattner 76c564b1bb change a ton of code to not implicitly use the "O" raw_ostream 
member of AsmPrinter.  Instead, pass it in explicitly.

Mon P Wang c576ee9040 Reapply address space patch after fixing an issue in MemCopyOptimizer. 
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

Chris Lattner f33c7fcc28 asmstreamerize the .size directive for function bodies, force clients 
of printOffset to pass in a stream to print to.

Eric Christopher 000e502eb1 Rewrite aesimc handling. It only takes a single input and has a single 
dest.

llvm-svn: 100252
 2010-04-02 23:48:33 +00:00
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.

Sean Callanan 010b373cf3 Fixes to the X86 disassembler. The disassembler will now 
return an error status in all failure cases, printing
messages to debugs() only when debugging is enabled.

Dale Johannesen 4244d12769 Teach AnalyzeBranch, RemoveBranch and the branch

Evan Cheng 4c014c892a - Avoid using floating point stores to implement memset unless the value is zero. 
- Do not try to infer GV alignment unless its type is sized. It's not possible to infer alignment if it has opaque type.

Evan Cheng 43cd9e3845 Fix sdisel memcpy, memset, memmove lowering: 
1. Makes it possible to lower with floating point loads and stores.
2. Avoid unaligned loads / stores unless it's fast.
3. Fix some memcpy lowering logic bug related to when to optimize a
   load from constant string into a constant.
4. Adjust x86 memcpy lowering threshold to make it more sane.
5. Fix x86 target hook so it uses vector and floating point memory
   ops more effectively.

Eric Christopher 9002ac5d93 Add aeskeygenassist intrinsic and rename all of the aes intrinsics to 
aes instead of sse4.2.  Add a brief todo for a subtarget flag and rework
the aeskeygenassist instruction to more closely match the docs.

 2010-03-30 22:47:00 +00:00
Jakob Stoklund Olesen 3493398f13 V_SETALLONES is an integer instruction. 
Since it is just a pxor in disguise, we should probably expand it to a full
polymorphic triple.

llvm-svn: 99953
 2010-03-30 22:46:55 +00:00
Jakob Stoklund Olesen dbff4e8103 Renumber SSE execution domains for better code size. 
SSEDomainFix will collapse to the domain with the lower number when it has a
choice. The SSEPackedSingle domain often has smaller instructions, so prefer
that.

Jakob Stoklund Olesen cf35648ebe Revert "Enable -sse-domain-fix by default. What could possibly go wrong?" 
Not running 'make check-all' before committing is a bad idea.

e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)
A update of langref will occur in a subsequent checkin.

Eric Christopher 6ad8167714 Remove the pmulld intrinsic and autoupdate it as a vector multiply. 
Rewrite the pmulld patterns, and make sure that they fold in loads of
arguments into the instruction.

Chris Lattner 9897043928 Rip out the 'is temporary' nonsense from the MCContext interface to 
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

 2010-03-30 00:09:32 +00:00
Jakob Stoklund Olesen b551aa4da5 Basic implementation of SSEDomainFix pass. 
Cross-block inference is primitive and wrong, but the pass is working otherwise.

Benjamin Kramer 2788f797ca Make isInt?? and isUint?? template specializations of the generic versions. This 
makes calls a little bit more consistent and allows easy removal of the
specializations in the future. Convert all callers to the templated functions.

Eric Christopher 9bdadf0d99 We'll never match these as instructions, just as intrinsics so remove
