*	PowerPC: strncpy/stpncpy optimization for PPC64/POWER7	Vidya Ranganathan	2014-05-06	1	-0/+16
\| \| \| \| \| \| \| \|	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
*	PowerPC: optimized strpbrk for POWER7	Adhemerval Zanella	2014-03-20	1	-0/+8
\| \| \| \| \| \| \| \| \|	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.
*	PowerPC: optimized strcspn for PPC64/POWER7	Adhemerval Zanella	2014-03-20	1	-0/+8
\| \| \| \| \| \| \| \| \| \|	This patch add a optimized strcspn 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 align stack memory to table to 16 bytes (so VSX clean can ran without alignment issues).
*	PowerPC: strspn optimization for PPC64/POWER7	Vidya Ranganathan	2014-03-11	1	-0/+8
\| \| \| \| \| \| \| \|	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.
*	PowerPC: strncat optimization for PPC64	Adhemerval Zanella	2014-03-10	1	-0/+8
\| \| \| \| \| \| \| \|	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.
*	PowerPC: strrchr optimization for POWER7/PPC64	Rajalakshmi Srinivasaraghavan	2014-03-03	1	-0/+8
\| \| \| \| \| \|	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.
