2009-09-07Reappy r80998, now that the GlobalOpt bug that it exposed on MiniSAT is fixed.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81172 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-07Fix a thinko: When lowering fneg with xor, bitcast the operandsDan Gohman
from floating-point to integer first, and bitcast the result back to floating-point. Previously, this test was passing by falling back to SelectionDAG lowering. The resulting code isn't as nice, but it's correct and CodeGen now stays on the fast path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81171 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81168 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-07Add inbounds to these getelementptrs, now that GlobalOpt requires this,Dan Gohman
to preserve the meaning of these tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81166 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-07Don't commit stores with addresses that have indices that are notDan Gohman
compile-time constant integers or that are out of bounds for their corresponding static array types. These can cause aliasing that GlobalOpt assumes won't happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81165 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-07Don't commit addresses of aggregate values. This avoids problems withDan Gohman
an aggregate store overlapping a different aggregate store, despite the stores having distinct addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81164 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-07Fix GlobalOpt to avoid committing a store if the address getelementptrDan Gohman
is missing the inbounds flag. This is slightly conservative, but it avoids problems with two constants pointing to the same address but getting distinct entries in the Memory DenseMap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81163 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-07Use -output-prefix in bugpoint tests so that outputs go in temp directory (andDaniel Dunbar
we don't race on them). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81155 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-07Avoid Tcl substitution, introduced %llvmgcc_only for this one little testDaniel Dunbar
(%llvmgcc includes a '-w' argument, and this test looks for warnings). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81152 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-06Do not try to override non-virtual methods, especiallyDuncan Sands
when the new method gives the same result as the original (as far as I can see). This will hopefully pacify icc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81131 91177308-0d34-0410-b5e6-96231b3b80d8
