Adhemerval Zanella	de21c33c06	PowerPC: Fix --disable-multi-arch builds This patch fixes some powerpc32 and powerpc64 builds with --disable-multi-arch option along with different --with-cpu=powerN. It cleanups the Implies directories by removing the multiarch folder for non multiarch config and also fixing two assembly implementations: powerpc64/power7/strncat.S that is calling the wrong strlen; and power8/fpu/s_isnan.S that misses the hidden_def and weak_alias directives.	2014-04-09 06:22:53 -05:00
Adhemerval Zanella	ba9cc0714e	PowerPC: strncat optimization for PPC64 The optimization is achieved by following techniques: 1. Doubleword aligned memory access and compares using cmpb instruction. 2. Loop unrolling for byte load/store. 3. CPU pre-fetch to avoid cache miss.	2014-03-10 07:25:09 -05:00

PowerPC: Fix --disable-multi-arch builds

This patch fixes some powerpc32 and powerpc64 builds with
--disable-multi-arch option along with different --with-cpu=powerN.
It cleanups the Implies directories by removing the multiarch
folder for non multiarch config and also fixing two assembly
implementations: powerpc64/power7/strncat.S that is calling the
wrong strlen; and power8/fpu/s_isnan.S that misses the hidden_def and
weak_alias directives.

PowerPC: strncat optimization for PPC64

The optimization is achieved by following techniques:
1. Doubleword aligned memory access and compares using
   cmpb instruction.
2. Loop unrolling for byte load/store.
3. CPU pre-fetch to avoid cache miss.
