[LLVMdev] FileCheck for instructions of indeterminate order?
...a reproducible
order on my PowerPC machine, various buildbots of other architectures
produced codegen in a different order when cross-compiling to PowerPC.
Needless to say, the test is XFAILed until I can figure a way to test
this more safely.
All help appreciated!
Thanks,
Bill
N.B. I found the nondeterminacy at -O0 to be somewhat surprising...is
there some other option I need to avoid instruction reordering?
