--- Comment #2 from ktkachov at gcc dot gnu.org --- Created attachment 45386 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45386&action=edit aarch64-llvm output with -Ofast -mcpu=cortex-a57 I'm attaching the full LLVM aarch64 output. The output you quoted is with -funroll-loops. If that's not given, GCC doesn't seem to unroll by default at all (on aarch64 or x86_64 from my testing). Is there anything we can do to make the default unrolling a bit more aggressive?
