2009-09-03Test cases for vector shifts changes r80935Mon P Wang
Changed the old vector shift test to use FileCheck git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80936 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Fixed a few problems with vector shiftsMon P Wang
- when transforming a vector shift of a non-immediate scalar shift amount, zero extend the i32 shift amount to i64 since the vector shift reads 64 bits - when transforming i16 vectors to use a vector shift, zero extend i16 shift amount - improve the code quality in some cases when transforming vectors to use a vector shift git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80935 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Add a -disable-16bit flag and associated support for experimenting withDan Gohman
disabling the use of 16-bit operations on x86. This doesn't yet work for inline asms with 16-bit constraints, vectors with 16-bit elements, trampoline code, and perhaps other obscurities, but it's enough to try some experiments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80930 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Removed the non-target independent AsmToken::Register enum constantKevin Enderby
from MCAsmLexer.h in preparation of supporting other targets. Changed the X86AsmParser code to reflect this by removing AsmLexer::LexPercent and looking for AsmToken::Percent when parsing in places that used AsmToken::Register. Then changed X86ATTAsmParser::ParseRegister to parse out registers as an AsmToken::Percent followed by an AsmToken::Identifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80929 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03Add a verifyAnalysis to LoopInfo, LoopSimplify, and LCSSA form that verifyDan Gohman
that these passes are properly preserved. Fix several transformation passes that claimed to preserve LoopSimplify form but weren't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80926 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03Move getUniqueExitBlocks from LoopBase to Loop, since they depend onDan Gohman
LoopSimplify form, which is currently only available on Loops (and not MachineLoops). Also, move the code out of the header file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80923 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03Change PHINode::hasConstantValue to have a DominatorTree argumentDan Gohman
instead of a bool argument, and to do the dominator check itself. This makes it eaiser to use when DominatorTree information is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80920 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03Set the 'cached digest' flag after computing the digest for anTed Kremenek
ImutAVLTree. This was accidentally left out, and essentially caused digest caching to be ignored in ImmutableMap and ImmutableSet (this bug was detected from shark traces that showed ComputeDigest was in the hot path in the clang static analyzer). This reduces the running time of the clang static analyzer on an example benchmark by ~32% for both RegionStore (field-sensitivty) and BasicStore (without field-sensitivity). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80877 91177308-0d34-0410-b5e6-96231b3b80d8
