Force a triple on a couple of tests; we don't support fast-isel of ret on Win64. llvm-svn: 131540

; RUN: llc < %s -fast-isel -fast-isel-abort -mtriple=x86_64-apple-darwin10 | FileCheck %s
Rewrite some of the test/CodeGen/X86 tests to use FileCheck instead of grep llvm-svn: 179241

; SSE2: xor
Add a CHECK-NOT for a more faithful translation of the original grep | count 2. Thanks to Reid Kleckner for catching this. llvm-svn: 179289

; SSE2-NOT: xor
LLVM currently represents floating-point negation as -0.0 - x. Fix FastISel to recognize this pattern and emit a floating-point negation using xor. llvm-svn: 80963
2009-09-04 00:53:57 +02:00
Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally. This update was done with the following bash script: find test/CodeGen -name "*.ll" | \ while read NAME; do echo "$NAME" if ! grep -q "^; *RUN: *llc.*debug" $NAME; then TEMP=`mktemp -t temp` cp $NAME $TEMP sed -n "s/^define [^@]*@\([A-Za-z0-9_]*\)(.*$/\1/p" < $NAME | \ while read FUNC; do sed -i '' "s/;\(.*\)\([A-Za-z0-9_-]*\):\( *\)$FUNC: *\$/;\1\2-LABEL:\3$FUNC:/g" $TEMP done sed -i '' "s/;\(.*\)-LABEL-LABEL:/;\1-LABEL:/" $TEMP sed -i '' "s/;\(.*\)-NEXT-LABEL:/;\1-NEXT:/" $TEMP sed -i '' "s/;\(.*\)-NOT-LABEL:/;\1-NOT:/" $TEMP sed -i '' "s/;\(.*\)-DAG-LABEL:/;\1-DAG:/" $TEMP mv $TEMP $NAME fi done llvm-svn: 186280
