* revert r170166 - disable the loop vectorizer.Nadav Rotem2012-12-141-1/+1

| | | | llvm-svn: 170162
* Use the new MI bundling API in MachineInstrBundle itself.Jakob Stoklund Olesen2012-12-131-4/+5
| | | | | | | The new API is higher level than just manipulating the bundle flags directly, and the setIsInsideBundle() function will disappear soon. llvm-svn: 170159
* Remove two popcount patterns which we are already able to recognize.Shuxin Yang2012-12-131-15/+0
| | | | llvm-svn: 170158
* Enable the Loop Vectorizer by default for O2 and O3. Disable if-conversion ↵Nadav Rotem2012-12-132-2/+2
| | | | | | by default. I plan to revert this patch later today. llvm-svn: 170157
* Debug Info: add support to mark member variables as artificialDavid Blaikie2012-12-131-0/+3
| | | | | | This is the LLVM portion of r170154. llvm-svn: 170156
* This is another cleanup patch for 64-bit PowerPC TLS processing. I hadBill Schmidt2012-12-133-57/+11
| | | | | | | some hackery in place that hid my poor use of TblGen, which I've now sorted out and cleaned up. No change in observable behavior, so no new test cases. llvm-svn: 170149
* Change TargetLowering::setTypeAction to take an MVT, instead fo EVT.Patrik Hagglund2012-12-131-1/+1
| | | | llvm-svn: 170148
* Fix warnings with -DNDEBUGTom Stellard2012-12-133-2/+3
| | | | | | Patch by: NAKAMURA Takumi llvm-svn: 170142
* This is just a clean-up patch that simplifies the initial-exec TLS logic byBill Schmidt2012-12-134-19/+7
| | | | | | | avoiding use of machine operand flags. No change in observable behavior, so no new test cases. llvm-svn: 170141
* Change TargetLowering::getRepRegClassFor to take an MVT, instead ofPatrik Hagglund2012-12-134-12/+12
| | | | | | | | EVT. Accordingly, change RegDefIter to contain MVTs instead of EVTs. llvm-svn: 170140
* Revert r170020, "Simplify negated bit test", for now.NAKAMURA Takumi2012-12-131-18/+0
| | | | | | | | | This assumes (1 << n) is always not zero. Consider n is greater than word size. Although I know it is undefined, this transforms undefined behavior hidden. This led clang unexpected behavior with some failures. I will investigate to fix undefined shl in clang. llvm-svn: 170128
* Revert "Restore the PHI optimization I accidently removed" temporarily sinceEric Christopher2012-12-131-4/+0
| | | | | | | | it seems to be breaking self-host for a few people and is PR14592. This reverts commit r170024. llvm-svn: 170106
* Revert "Add a funciton to get the segment name of a section."Eric Christopher2012-12-131-25/+10
| | | | | | This reverts commit r170095 since it appears to be breaking the bots. llvm-svn: 170105
* Change TargetLowering::getRegClassFor to take an MVT, instead of EVT.Patrik Hagglund2012-12-1310-76/+70
| | | | | | | | | | | | Accordingly, add helper funtions getSimpleValueType (in parallel to getValueType) in SDValue, SDNode, and TargetLowering. This is the first, in a series of patches. This is the second attempt. In the first attempt (r169837), a few getSimpleVT() were hoisted too far, detected by bootstrap failures. llvm-svn: 170104
* Add a funciton to get the segment name of a section.Rafael Espindola2012-12-131-10/+25
| | | | | | | | | | | | | | | On MachO, sections also have segment names. When a tool looking at a .o file prints a segment name, this is what they mean. In reality, a .o has only one, anonymous, segment. This patch adds a MachO only function to fetch that segment name. I named it getSectionFinalSegmentName since the main use for the name seems to be informing the linker with segment this section should go to. The patch also changes MachOObjectFile::getSectionName to return just the section name instead of computing SegmentName,SectionName. llvm-svn: 170095
* Missed these calls from the previous rename somehow.Rafael Espindola2012-12-131-2/+2
| | | | llvm-svn: 170094
* Rename isPowerOfTwo to isKnownToBeAPowerOfTwo.Rafael Espindola2012-12-133-15/+15
| | | | | | | | In a previous thread it was pointed out that isPowerOfTwo is not a very precise name since it can return false for powers of two if it is unable to show that they are powers of two. llvm-svn: 170093

* Pattern matching code for intrinsics.Michael Ilseman2012-12-131-15/+17
| | | | | | Provides m_Argument that allows matching against a CallSite's specified argument. Provides m_Intrinsic pattern that can be templatized over the intrinsic id and bind/match arguments similarly to other pattern matchers. Implementations provided for 0 to 4 arguments, though it's very simple to extend for more. Also provides example template specialization for bswap (m_BSwap) and example of code cleanup for its use. llvm-svn: 170091

* Take into account minimize size attribute in the inliner.Quentin Colombet2012-12-131-2/+4
| | | | | | | | | Better controls the inlining of functions when the caller function has MinSize attribute. Basically, when the caller function has this attribute, we do not "force" the inlining of callee functions carrying the InlineHint attribute (i.e., functions defined with inline keyword) llvm-svn: 170065

* [ms-inline asm] Make sure we fail gracefully on parse errors. Parse errorsChad Rosier2012-12-121-2/+9
| | | | | | | | should only occur on invalid input. Instruction matching errors aren't unexpected, so we can't rely on the AsmParsers HadError variable directly. rdar://12840278 llvm-svn: 170037
