PowerPC: memset optimization for POWER8/PPC64 This patch adds an optimized memset implementation for POWER8. For sizes from 0 to 255 bytes, a word/doubleword algorithm similar to POWER7 optimized one is used. For size higher than 255 two strategies are used: 1. If the constant is different than 0, the memory is written with altivec vector instruction; 2. If constant is 0, dbcz instructions are used. The loop is unrolled to clear 512 byte at time. Using vector instructions increases throughput considerable, with a double performance for sizes larger than 1024. The dcbz loops unrolls also shows performance improvement, by doubling throughput for sizes larger than 8192 bytes. 2014-07-15 16:19:09 +00:00			`memset-ppc64 memset-power8 \`

PowerPC: strrchr optimization for POWER7/PPC64 This patch optimizes strrchr() for ppc64. It uses aligned memory access along with cmpb instruction and CPU prefetch to avoid cache misses for speed improvement. 2014-03-03 14:06:41 +00:00			`strcpy-power7 strcpy-ppc64 stpcpy-power7 stpcpy-ppc64 \`
PowerPC: strspn optimization for PPC64/POWER7 The optimization is achieved by following techniques: > hashing of needle. > hashing avoids scanning of duplicate entries in needle across the string. > initializing the hash table with Vector instructions (VSX) by quadword access. > unrolling when scanning for character in string across hash table. 2014-03-10 16:20:36 +00:00			`strrchr-power7 strrchr-ppc64 strncat-power7 strncat-ppc64 \`
PowerPC: strncpy/stpncpy optimization for PPC64/POWER7 The optimization is achieved by following techniques: > data alignment [gain from aligned memory access on read/write] > POWER7 gains performance with loop unrolling/unwinding [gain by reduction of branch penalty]. > zero padding done by calling optimized memset 2014-05-06 00:10:45 +00:00			`strpbrk-power7 strpbrk-ppc64 strncpy-power7 strncpy-ppc64 \`
PowerPC: strcat optimization for PPC64/POWER7 This patch adds an ifunc power7 strcat symbol that uses the logic on sysdeps/powerpc/strcat.c but call power7 strlen/strcpy symbols instead of default ones. 2014-06-12 03:21:20 +00:00			`stpncpy-power7 stpncpy-ppc64 strcmp-power7 strcmp-ppc64 \`
PowerPC: optimized memmove for POWER7/PPC64 This patch adds an optimized memmove optimization for POWER7/powerpc64. Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment. The difference is memory is always aligned to 16 bytes before using VSX/altivec instructions. 2014-06-20 17:55:16 +00:00			`strcat-power7 strcat-ppc64 memmove-power7 memmove-ppc64 \`
