This commit copies existing tests at llvm/Transforms containing 'shufflevector X, undef' and replaces them with 'shufflevector X, poison'. The new copied tests have *-inseltpoison.ll suffix at its file name (as db7a2f347f132b3920415013d62d1adfb18d8d58 did) See https://reviews.llvm.org/D93793 Test files listed using grep -R -E "^[^;]*shufflevector <.*> .*, <.*> undef" | cut -d":" -f1 | uniq Test files copied & updated using file_org=llvm/test/Transforms/$1 if [[ "$file_org" = *-inseltpoison.ll ]]; then file=$file_org else file=${file_org%.ll}-inseltpoison.ll if [ ! -f $file ]; then cp $file_org $file fi fi sed -i -E 's/^([^;]*)shufflevector <(.*)> (.*), <(.*)> undef/\1shufflevector <\2> \3, <\4> poison/g' $file head -1 $file | grep "Assertions have been autogenerated by utils/update_test_checks.py" -q if [ "$?" == 1 ]; then echo "$file : should be manually updated" # The test is manually updated exit 1 fi python3 ./llvm/utils/update_test_checks.py --opt-binary=./build-releaseassert/bin/opt $file
