2011-10-18Revert "Turn on the vzeroupper pass by default."Eric Christopher
This reverts commit 494f7ac3e8d2ab3d94e52317abf9c42a949fe1f3. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142455 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-18Turn on the vzeroupper pass by default.Eric Christopher
I'll remove/rename the option in a few days. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142439 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-11Fixed natural stack alignment for Linux x86-32. Thanks Eli.Lang Hames
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141616 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-10Add a natural stack alignment field to TargetData, and prevent InstCombine fromLang Hames
promoting allocas to preferred alignments that exceed the natural alignment. This avoids some potentially expensive dynamic stack realignments. The natural stack alignment is set in target data strings via the "S<size>" option. Size is in bits and must be a multiple of 8. The natural stack alignment defaults to "unspecified" (represented by a zero value), and the "unspecified" value does not prevent any alignment promotions. Target maintainers that care about avoiding promotions should explicitly add the "S<size>" option to their target data strings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141599 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-27Remove X86-dependent stuff from SSEDomainFix.Jakob Stoklund Olesen
This also enables domain swizzling for AVX code which required a few trivial test changes. The pass will be moved to lib/CodeGen shortly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140659 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15Enable SSEDomainFix pass for AVX mode.Bruno Cardoso Lopes
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139816 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-03Use internal storage for command line option.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139079 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-24Move TargetRegistry and TargetSelect from Target to Support where they belong.Evan Cheng
These are strictly utilities for registering targets and components. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138450 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-23Introduce a pass to insert vzeroupper instructions to avoid AVX toBruno Cardoso Lopes
SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper" llc command line option. This is only the first step (very naive and conservative one) to sketch out the idea, but proper DFA is coming next to allow smarter decisions. Comments and ideas now and in further commits will be very appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138317 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-25More refactoring.Evan Cheng

2011-07-20- Move CodeModel from a TargetMachine global option to MCCodeGenInfo.Evan Cheng
- Introduce JITDefault code model. This tells targets to set different default code model for JIT. This eliminates the ugly hack in TargetMachine where code model is changed after construction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135580 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19Introduce MCCodeGenInfo, which keeps information that can affect codegenEvan Cheng
(including compilation, assembly). Move relocation model Reloc::Model from TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135468 91177308-0d34-0410-b5e6-96231b3b80d8

MCTargetDesc to prepare for next round of changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135219 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-11- Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng
and MCSubtargetInfo. - Added methods to update subtarget features (used when targets automatically detect subtarget features or switch modes). - Teach X86Subtarget to update MCSubtargetInfo features bits since the MCSubtargetInfo layer can be shared with other modules. - These fixes .code 16 / .code 32 support since mode switch is updated in MCSubtargetInfo so MC code emitter can do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134884 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-08Eliminate asm parser's dependency on TargetMachine:Evan Cheng
- Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134678 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-30Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng
be the first encoded as the first feature. It then uses the CPU name to look up features / scheduling itineray even though clients know full well the CPU name being used to query these properties. The fix is to just have the clients explictly pass the CPU name! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134127 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-17Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 generally.NAKAMURA Takumi
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125747 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-16Remove the X86::FP_REG_KILL pseudo-instruction and the X86FloatingPointRegKillJakob Stoklund Olesen
pass that inserted it. It is no longer necessary to limit the live ranges of FP registers to a single basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108536 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-16Allow x87 FP registers to be alive globally in a function.Jakob Stoklund Olesen
FP_REG_KILL instructions are still inserted, but can be disabled by passing -live-x87 to llc. The X87FPRegKillInserterPass is going to be removed shortly. CFG edges are partioned into bundles where the x87 stack must be allocated identically. Code is insertad at the end of each basic block that shuffles the live FP registers to match the outgoing bundles expectations. This fix is in preparation for some upcoming register allocator improvements that may extend the live range of registers beyond a basic block, similar to LICM. It also provides a nice runtime speedup if you are building with -mfpmath=387. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108529 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-10Reapply bottom-up fast-isel, with several fixes for x86-32:Dan Gohman
- Check getBytesToPopOnReturn(). - Eschew ST0 and ST1 for return values. - Fix the PIC base register initialization so that it doesn't ever fail to end up the top of the entry block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108039 91177308-0d34-0410-b5e6-96231b3b80d8
