Stephen Lin	8b2b8a1835	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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186280 91177308-0d34-0410-b5e6-96231b3b80d8	2013-07-14 06:24:09 +00:00
Nadav Rotem	b9d6b8449d	Reapply r162160 with a fix: Optimize Arith->Trunc->SETCC sequence to allow better compare/branch code. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162172 91177308-0d34-0410-b5e6-96231b3b80d8	2012-08-18 17:53:03 +00:00
Nadav Rotem	d5c66a0b1f	Revert r162160 because it made a few buildbots fail. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162164 91177308-0d34-0410-b5e6-96231b3b80d8	2012-08-18 05:02:36 +00:00
Nadav Rotem	b5838689c6	The X86 backend has a number of optimizations for SETCC nodes which use ... arithmetic instructions. However, when small data types are used, a truncate node appears between the SETCC node and the arithmetic operation. This patch adds support for this pattern.
