--- 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
