--- Comment #6 from PeteVine <tulipawn at gmail dot com> --- Yes, Gcc 6 seems to be affected too. The flags used were explicitly shown on the phoronix graph (cortex-a53), but generic codegen might possibly suffer as well, similar to my discovery in: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53659#c3 Incidentally, the other issue provides step-by-step manual instructions for compiling and running the same benchmark version.
