2012-06-01PR1255: case ranges.Stepan Dyatkovskiy
IntegersSubset devided into IntegersSubsetGeneric and into IntegersSubset itself. The first has no references to ConstantInt and works with IntItem only. IntegersSubsetMapping also made generic. Here added second template parameter "IntegersSubsetTy" that allows to use on of two IntegersSubset types described below. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157815 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-01PR1255: case ranges.Stepan Dyatkovskiy
IntItem cleanup. IntItemBase, IntItemConstantIntImp and IntItem merged into IntItem. All arithmetic operators was propogated from APInt. Also added comparison operators <,>,<=,>=. Currently you will find set of macros that propogates operators from APInt to IntItem in the beginning of IntegerSubset. Note that THESE MACROS WILL REMOVED after all passes will case-ranges compatible. Also note that these macros much smaller pain that something like this: if (V->getValue().ugt(AnotherV->getValue()) { ... } These changes made IntItem full featured integer object. It allows to make IntegerSubset class generic (move out all ConstantInt references inside and add unit-tests) in next commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157810 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-31revamp BoundsChecking considerably:Nuno Lopes
- compute size & offset at the same time. The side-effects of this are that we now support negative GEPs. It's now approaching a phase that it can be reused by other passes (e.g., lowering of the objectsize intrinsic) - use APInt throughout to handle wrap-arounds - add support for PHI instrumentation - add a cache (required for recursive PHIs anyway) - remove hoisting support for now, since it was wrong in a few cases sorry for the churn here.. tests will follow soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157775 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-31Add a PrintRegUnit helper similar to PrintReg.Jakob Stoklund Olesen
Reg-units are named after their root registers, and most units have a single root, so they simply print as 'AL', 'XMM0', etc. The rare dual root reg-units print as FPSCR~FPSCR_NZCV, FP0~ST7, ... The printing piggybacks on the existing register name tables, so no extra const data space is required. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157754 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-31X86: Rename the CLMUL target feature to PCLMUL.Benjamin Kramer
It was renamed in gcc/gas a while ago and causes all kinds of confusion because it was named differently in llvm and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157745 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-31Require intervals in the range metadata to be in a canonical form: They mustRafael Espindola
be non contiguous, non overlapping and sorted by the lower end. While this is technically a backward incompatibility, every frontent currently produces range metadata with a single interval and we don't have any pass that merges intervals yet, so no existing bitcode files should be rejected by this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157741 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-30Prioritize smaller register classes for urgent evictions.Jakob Stoklund Olesen
It helps compile exotic inline asm. In the test case, normal GR32 virtual registers use up eax-edx so the final GR32_ABCD live range has no registers left. Since all the live ranges were tiny, we had no way of prioritizing the smaller register class. This patch allows tiny unspillable live ranges to be evicted by tiny unspillable live ranges from a smaller register class. <rdar://problem/11542429> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157715 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-30Reinstate -O3 for LTO.David Blaikie
This broke in r144788 when the CodeGenOpt option was moved from everywhere else (specifically, from addPassesToEmitFile) to createTargetMachine. Since LTOCodeGenerator wasn't passing the 4th argument, when the 4th parameter became the 3rd, it silently continued to compile (int->bool conversion) but meant something completely different. This change preserves the existing (accidental) and previous (default) semantics of the addPassesToEmitFile and restores the previous/intended CodeGenOpt argument by passing it appropriately to createTargetMachine. (discovered by pending changes to -Wconversion to catch constant->bool conversions) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157705 91177308-0d34-0410-b5e6-96231b3b80d8
