2009-05-28Remove special cases for more opcodes.Eli Friedman
This is basically the end of this series of patches for LegalizeDAG; the remaining special cases can't be removed without more infrastructure work. There's a FIXME for each relevant opcode near the beginning of SelectionDAGLegalize::LegalizeOp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72514 91177308-0d34-0410-b5e6-96231b3b80d8

the Intel manual (screenshot) says it should be 0b11110110 (f6). The existing encoding causes a disassembly conflict with MMX_PAVGBrm, which really should be 0f e0." Patch by Sean Callanan! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72508 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-28Added optimization that narrow load / op / store and the 'op' is a bit ↵Evan Cheng
twiddling instruction and its second operand is an immediate. If bits that are touched by 'op' can be done with a narrower instruction, reduce the width of the load and store as well. This happens a lot with bitfield manipulation code. e.g. orl $65536, 8(%rax) => orb $1, 10(%rax) Since narrowing is not always a win, e.g. i32 -> i16 is a loss on x86, dag combiner consults with the target before performing the optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72507 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Revert 72493 and replace it with a more conservative fix, for now: don'tDan Gohman

2009-05-27Teach SCEVExpander to avoid creating over-indexed GEP indices whenDan Gohman
possible. For example, it now emits %p.2.ip.1 = getelementptr [3 x [3 x double]]* %p, i64 2, i64 %tmp, i64 1 instead of the equivalent but less obvious %p.2.ip.1 = getelementptr [3 x [3 x double]]* %p, i64 0, i64 %tmp, i64 19 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72452 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Teach BasicAliasAnalysis to understand constant gep indices that fallDan Gohman
beyond their associated static array type. I believe that this fixes a legitimate bug, because BasicAliasAnalysis already has code to check for this condition that works for non-constant indices, however it was missing the case of constant indices. With this change, it checks for both. This fixes PR4267, and miscompiles of SPEC 188.ammp and 464.h264.href. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72451 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-26For the new ar --plugin libLLVMgold.so to work we need libLTO linked withTorok Edwin
pthreads, otherwise ar complains of unresolved references to pthread_mutex_*. LTO doesn't actually use pthreads, but ManagedStatic does. Fix this by linking in LIBS (that contains pthreads) for LTO and gold. For now this links in more libs than needed (libffi for example), we can figure out later how to link in those libs per-tool later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72430 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-26LiveVariables::VarInfo contains an AliveBlocks BitVector, which has as manyJeffrey Yasskin
entries as there are basic blocks in the function. LiveVariables::getVarInfo creates a VarInfo struct for every register in the function, leading to quadratic space use. This patch changes the BitVector to a SparseBitVector, which doesn't help the worst-case memory use but does reduce the actual use in very long functions with short-lived variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72426 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-26For the return type of SCEVUDivExpr, use the RHS' type instead ofDan Gohman
that of the LHS. It doesn't matter for correctness, but the LHS is more likely than the RHS to be a pointer type in exotic cases, and it's more tidy to have it return the integer type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72424 91177308-0d34-0410-b5e6-96231b3b80d8
