From 759cfef3ac4c07dba1ece0bbc1207e099348816d Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Sat, 17 Aug 2013 18:47:22 +0930 Subject: PowerPC LE memcpy http://sourceware.org/ml/libc-alpha/2013-08/msg00103.html LIttle-endian support for memcpy. I spent some time cleaning up the 64-bit power7 memcpy, in order to avoid the extra alignment traps power7 takes for little-endian. It probably would have been better to copy the linux kernel version of memcpy. * sysdeps/powerpc/powerpc32/power4/memcpy.S: Add little endian support. * sysdeps/powerpc/powerpc32/power6/memcpy.S: Likewise. * sysdeps/powerpc/powerpc32/power7/memcpy.S: Likewise. * sysdeps/powerpc/powerpc32/power7/mempcpy.S: Likewise. * sysdeps/powerpc/powerpc64/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power4/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power6/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/mempcpy.S: Likewise. Make better use of regs. Use power7 mtocrf.
