--- Comment #6 from Mike Lothian <mike at fireburn dot co.uk> --- I tried the test case with gcc -O2 -march=native test.c -o test and gcc -O2 -march=native -mno-bmi test.c -o test Both executables seem to run with no output I've only seen the issue in radeonsi in Mesa with LLVM, I'm not sure what's happening as the problem doesn't manifest when debugging is enabled so I'm not sure how to create a smaller test case
