I’m working on performance tuning a gcc 8.3 port and wanted to turn off SRA for an experiment. But passing both
-fno-tree-sra
-fno-ipa-sra
but it’s still tagging compiled functions with a “_isra” suffix, which would seem to indicate that it’s still running that optimization.
Is there a bigger hammer I’m missing?

Nope, that should do the trick already.
