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: Optimized st{r,p}cpy for POWER8/PPC64 This patch adds an optimized POWER8 strcpy using unaligned accesses. For strings up to 16 bytes the implementation first calculate the string size, like strlen, and issues a memcpy. For larger strings, source is first aligned to 16 bytes and then tested over a loop that reads 16 bytes am combine the cmpb results for speedup. Special case is added for page cross reads. It shows 30%-60% improvement over the optimized POWER7 one that uses only aligned accesses. 2014-12-23 11:59:44 +00:00			`strcpy-power8 strcpy-power7 strcpy-ppc64 stpcpy-power8 \`

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: Add powerpc64 strpbrk optimization This patch makes the POWER7 optimized strpbrk generic by using default doubleword stores to zero the hash, instead of VSX instructions. Performance on POWER7/POWER8 does not change. 2014-11-19 21:27:56 +00:00			`strncpy-power7 strncpy-ppc64 \`
