Bernhard Kaindl <bernhard.kaindl at thalesgroup dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bernhard.kaindl@thalesgroup | |.com --- Comment #15 from Bernhard Kaindl <bernhard.kaindl at thalesgroup dot com> --- Confirmed: * Fixed in: gcc-4.9.2 (release) * NOT Fixed in: gcc-4.8.4 (release) It seems indeed only i386, x32 and x86_64 (-m32, -mx32 and -m64) are affected. -fopt-info-vec-note show that e.g. powerpc & powerpc64 don't vectorize the loop. The mainline fix from Comment #8 apples without fuzz and fixes this wrong code issue in gcc-4.8.4. Apply it for 4.8.5?
