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: optimized strpbrk for POWER7 This patch add an optimized strpbrk for POWER7 by using a different algorithm than default implementation: it constructs a table based on the 'accept' argument and use this table to check for any occurance on the input string. The idea is similar as x86_64 uses. For PowerPC some tunings were added, such as unroll loops and memory clear using VSX instructions. 2014-03-20 20:28:07 +00:00			`strspn-power7 strspn-ppc64 strcspn-power7 strcspn-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: Optimized strcmp for PPC64/POWER7 Optimization is achieved on 8 byte aligned strings with double word comparison using cmpb instruction. On unaligned strings loop unrolling is applied for Power7 gain. 2014-06-06 12:56:07 +00:00			`stpncpy-power7 stpncpy-ppc64 strcmp-power7 strcmp-ppc64`
