| * | ARM & AArch64: make use of common cmpxchg idioms after expansion | Tim Northover | 2014-05-30 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | The C and C++ semantics for compare_exchange require it to return a bool indicating success. This gets mapped to LLVM IR which follows each cmpxchg with an icmp of the value loaded against the desired value. When lowered to ldxr/stxr loops, this extra comparison is redundant: its results are implicit in the control-flow of the function. This commit makes two changes: it replaces that icmp with appropriate PHI nodes, and then makes sure earlyCSE is called after expansion to actually make use of the opportunities revealed. I've also added -{arm,aarch64}-enable-atomic-tidy options, so that existing fragile tests aren't perturbed too much by the change. Many of them either rely on undef/unreachable too pervasively to be restored to something well-defined (particularly while making sure they test the same obscure assert from many years ago), or depend on a particular CFG shape, which is disrupted by SimplifyCFG. rdar://problem/16227836 llvm-svn: 209883 | ||||
| * | Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to ↵ | Stephen Lin | 2013-07-14 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 | ||||
| * | Use vld1 / vst2 for unaligned v2f64 load / store. e.g. Use vld1.16 for 2-byte | Evan Cheng | 2012-09-18 | 1 | -2/+2 |
| | | | | | | | | | | aligned address. Based on patch by David Peixotto. Also use vld1.64 / vst1.64 with 128-bit alignment to take advantage of alignment hints. rdar://12090772, rdar://12238782 llvm-svn: 164089 | ||||
