* Implement the local-dynamic TLS model for x86 (PR3985)Hans Wennborg2012-06-0113-17/+353
| | | | | | | | | This implements codegen support for accesses to thread-local variables using the local-dynamic model, and adds a clean-up pass so that the base address for the TLS block can be re-used between local-dynamic access on an execution path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157818 91177308-0d34-0410-b5e6-96231b3b80d8
* PR1255: case ranges.Stepan Dyatkovskiy2012-06-013-117/+141
| | | | | | | | | 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

* PR1255: case ranges.Stepan Dyatkovskiy2012-06-015-98/+142
| | | | | | | | | | | | 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

* revamp BoundsChecking considerably:Nuno Lopes2012-05-312-130/+231
| | | | | | | | | | | | - 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

* Add a PrintRegUnit helper similar to PrintReg.Jakob Stoklund Olesen2012-05-312-0/+44
| | | | | | | | | | | 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
* Emit register unit root tables.Jakob Stoklund Olesen2012-05-312-1/+63

| | | | | | | | | | | 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

* Prioritize smaller register classes for urgent evictions.Jakob Stoklund Olesen2012-05-302-1/+16
| | | | | | | | | | | | | | 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
