--- Comment #16 from Linus Torvalds <torva...@linux-foundation.org> --- (In reply to H.J. Lu from comment #14) > We should avoid testb optimization. This are latencies: > > testb : 33711871 > testw : 21204854 > testl : 18938530 > testq : 18942712 > > on Haswell. Most of other processors show that testb is the slowest. Those testb numbers are very interesting and quite unexpected. Can you share the test program? Are you sure it's not the high byte registers you tested somehow? Intriguing. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
