Subject: [PATCH 24/30] S390: Optimize strpbrk and wcspbrk.
upstream-commit-id: f0ba659847446eec3b2477d60c97c77ef4680e81
https://www.sourceware.org/ml/libc-alpha/2015-07/msg00091.html
This patch provides optimized versions of strpbrk and wcspbrk with the z13
vector instructions.
ChangeLog:
* sysdeps/s390/multiarch/strpbrk-c.c: New File.
* sysdeps/s390/multiarch/strpbrk-vx.S: Likewise.

* sysdeps/s390/multiarch/wcspbrk-c.c: Likewise.
* sysdeps/s390/multiarch/wcspbrk-vx.S: Likewise.
* sysdeps/s390/multiarch/wcspbrk.c: Likewise.
* sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strpbrk and
wcspbrk functions.
* sysdeps/s390/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Add ifunc test for strpbrk, wcspbrk.
* wcsmbs/wcspbrk.c: Use WCSPBRK if defined.
* string/test-strpbrk.c: Add wcspbrk support.
* wcsmbs/test-wcspbrk.c: New File.
* wcsmbs/Makefile (strop-tests): Add wcspbrk.

+/* char *strpbrk (const char *s, const char * accept)
+ The strpbrk() function locates the first occurrence in the string s
+ of any of the characters in the string accept and returns a pointer
+ to that character or NULL if not found.
+
+ This method checks the length of accept string. If it fits entirely
+ in one vector register, a fast algorithm is used, which does not need
+ to check multiple parts of accept-string. Otherwise a slower full
+ check of accept-string is used.
+
+ register overview:
+ r3: pointer to start of accept-string
+ r2: pointer to start of search-string
+ r0: loaded byte count of vlbb search-string (32bit unsigned)
+ r4: found byte index (32bit unsigned)
+ r1: current return len (64bit unsigned)
+ v16: search-string
+ v17: accept-string
+ v18: temp-vreg
+
+ ONLY FOR SLOW:
+ v19: first accept-string
+ v20: zero for preparing acc-vector
+ v21: global mask; 1 indicates a match between
+ search-string-vreg and any accept-character
+ v22: current mask; 1 indicates a match between
+ search-string-vreg and any accept-character in current acc-vreg
+ v24: one for result-checking of former string-part
+ v30, v31: for re-/storing registers r6, r8, r9
+ r5: current len of accept-string
+ r6: zero-index in search-string or 16 if no zero
