As part of the unification of the debug format and the MIR format, avoid printing "vreg" for virtual registers (which is one of the current MIR possibilities). Basically: * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E "s/%vreg([0-9]+)/%\1/g" * grep -nr '%vreg' . and fix if needed * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E "s/ vreg([0-9]+)/ %\1/g" * grep -nr 'vreg[0-9]\+' . and fix if needed Differential Revision: https://reviews.llvm.org/D40420 llvm-svn: 319427
