http://sourceware.org/ml/libc-alpha/2013-08/msg00104.html One of the things I noticed when looking at power7 timing is that rlwimi is cracked and the two resulting insns have a register dependency. That makes it a little slower than the equivalent rldimi. * sysdeps/powerpc/powerpc64/memset.S: Replace rlwimi with insrdi. Formatting. * sysdeps/powerpc/powerpc64/power4/memset.S: Likewise. * sysdeps/powerpc/powerpc64/power6/memset.S: Likewise. * sysdeps/powerpc/powerpc64/power7/memset.S: Likewise. * sysdeps/powerpc/powerpc32/power4/memset.S: Likewise. * sysdeps/powerpc/powerpc32/power6/memset.S: Likewise. * sysdeps/powerpc/powerpc32/power7/memset.S: Likewise. |
