*	powerpc: Add powerpc64 strpbrk optimization	Adhemerval Zanella	2014-12-02	1	-40/+0
\| \| \| \| \| \|	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.
*	PowerPC: optimized strpbrk for POWER7	Adhemerval Zanella	2014-03-20	1	-0/+40
	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.
