2012-12-19PowerPC: Expand VSELECT nodes.Benjamin Kramer
There's probably a better expansion for those nodes than the default for altivec, but this is better than crashing. VSELECTs occur in loop vectorizer output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170551 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-19Change AsmOperandInfo::ConstraintVT to MVT, instead of EVT.Patrik Hagglund

2012-12-19Revert 170545 while I debug the ppc failures.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170547 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-19Make TargetLowering::getTypeConversion more resilient against odd illegal MVTs.Benjamin Kramer
- An MVT can become an EVT when being split (e.g. v2i8 -> v1i8, the latter doesn't exist) - Return the scalar value when an MVT is scalarized (v1i64 -> i64) Fixes PR14639ff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170546 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-19Add r170095 back.Rafael Espindola
I cannot reproduce it the failures locally, so I will keep an eye at the ppc bots. This patch does add the change to the "Disassembly of section" message, but that is not what was failing on the bots. Original message: Add a funciton to get the segment name of a section. 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 infor 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170545 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-19[msan] Heuristically instrument unknown intrinsics.Evgeniy Stepanov
This changes adds shadow and origin propagation for unknown intrinsics by examining the arguments and ModRef behaviour. For now, only 3 classes of intrinsics are handled: - those that look like simple SIMD store - those that look like simple SIMD load - those that don't have memory effects and look like arithmetic/logic/whatever operation on simple types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170530 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-18Add to the disassembler C API an option to print the disassembledKevin Enderby
instructions in the assembly code variant if one exists. The intended use for this is so tools like lldb and darwin's otool(1) can be switched to print Intel-flavored disassembly. I discussed extensively this API with Jim Grosbach and we feel while it may not be fully general, in reality there is only one syntax for each assembly with the exception of X86 which has exactly two for historical reasons. rdar://10989182 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170477 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Remove MachineInstr::setIsInsideBundle().Jakob Stoklund Olesen
The bundle flags are now maintained by the slightly higher-level functions bundleWithPred() / bundleWithSucc() which enforce consistent bundle flags between neighboring instructions. See also MIBundleBuilder for an even higher-level approach to building bundles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170475 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Use bidirectional bundle flags to simplify important functions.Jakob Stoklund Olesen
The bundle_iterator::operator++ function now doesn't need to dig out the basic block and check against end(). It can use the isBundledWithSucc() flag to find the last bundled instruction safely. Similarly, MachineInstr::isBundled() no longer needs to look at iterators etc. It only has to look at flags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170473 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-18Verify bundle flags for consistency in MachineVerifier.Jakob Stoklund Olesen
The new bidirectional bundle flags are redundant, so inadvertent bundle tearing can be detected in the machine code verifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170463 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Disable ARM partial flag dependency optimization at -OzQuentin Colombet
To not over constrain the scheduler for ARM in thumb mode, some optimizations for code size reduction, specific to ARM thumb, are blocked when they add a dependency (like write after read dependency). Disables this check when code size is the priority, i.e., code is compiled with -Oz. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170462 91177308-0d34-0410-b5e6-96231b3b80d8
