--- Comment #12 from Venkataramanan <venkataramanan.kumar at amd dot com> --- (In reply to Allan Jensen from comment #11) > Btw, did you benchmark store splitting on AMD? It is also enabled for BDVER > and ZNVER1. I have not done that. As per SWOG for AMD15h (BDVER) it is advisable to split 256 bit stores. Also there is a old bug report which says splitting of store is better. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49089
