The formatting changes were to make it possible to compare power7 and power4 versions of memcmp. Using different register defines came about while I was wrestling with the code, trying to find spare registers at one stage. I found it much simpler if we refer to a reg by the same name throughout a function, so it's better if short-term multiple use regs like rTMP are referred to using their register number. I made the cr field usage changes when attempting to reload rWORDn regs in the exit path to byte swap before comparing when little-endian. That proved a bad idea due to the pipelining involved in the main loop; Offsets to reload the regs were different first time around the loop.. Anyway, I left the cr field usage changes in place for consistency. Aside from these more-or-less cosmetic changes, I fixed a number of places where an early exit path restores regs unnecessarily, removed some dead code, and optimised one or two exits. * sysdeps/powerpc/powerpc64/power7/memcmp.S: Add little-endian support. Formatting. Consistently use rXXX register defines or rN defines. Use early exit labels that avoid restoring unused non-volatile regs. Make cr field use more consistent with rWORDn compares. Rename regs used as shift registers for unaligned loop, using rN defines for short lifetime/multiple use regs. * sysdeps/powerpc/powerpc64/power4/memcmp.S: Likewise. * sysdeps/powerpc/powerpc32/power7/memcmp.S: Likewise. Exit with addi 1,1,64 to pop stack frame. Simplify return value code. * sysdeps/powerpc/powerpc32/power4/memcmp.S: Likewise.
