Unfortunately no one worked on reviewing it. It would be good to have it for 2.37, although I think it is too late. However, since most architectures do use arch-specific routines, I think the possible disruption of using this patchset should be minimal.

It is done by: 1. parametrizing the internal routines (for instance the find zero in a word) so each architecture can reimplement without the need to reimplement the whole routine. 2. vectorizing more string implementations (for instance strcpy and strcmp). 3. Change some implementations to use already possible optimized ones (for instance strnlen). It makes new ports to focus on only provide optimized implementation of a hardful symbols (for instance memchr) and make its improvement to be used in a larger set of routines. For the rest of #5806 I think we can handle them later and if performance of generic implementation is closer I think it is better to just remove old assembly implementations. I also checked on x86_64-linux-gnu, i686-linux-gnu, powerpc-linux-gnu, and powerpc64-linux-gnu by removing the arch-specific assembly implementation and disabling multiarch (it covers both LE and BE for 64 and 32 bits). I also checked the string routines on alpha, hppa, and sh. Changes since v4: * Removed __clz and __ctz in favor of count_leading_zero and count_trailing_zeros from longlong.h. * Use repeat_bytes more often. * Added a comment on strcmp final_cmp on why index_first_zero_ne can not be used. Changes since v3: * Rebased against master. * Dropped strcpy optimization. * Refactor strcmp implementation. * Some minor changes in comments. Changes since v2: * Move string-fz{a,b,i} to its own patch. * Add a inline implementation for __builtin_c{l,t}z to avoid using compiler provided symbols. * Add a new header, string-maskoff.h, to handle unaligned accesses on some implementation. * Fixed strcmp on LE machines. * Added a unaligned strcpy variant for architecture that define _STRING_ARCH_unaligned. * Add SH string-fzb.h (which uses cmp/str instruction to find a zero in word). Changes since v1: * Marked ChangeLog entries with [BZ #5806], as appropriate. * Reorganized the headers, so that armv6t2 and power6 need override as little as possible to use their (integer) zero detection insns. * Hopefully fixed all of the coding style issues. * Adjusted the memrchr algorithm as discussed. * Replaced the #ifdef STRRCHR etc that are used by the multiarch * files. * Tested on i386, i686, x86_64 (verified this is unused), ppc64, ppc64le --with-cpu=power8 (to use power6 in multiarch), armv7, aarch64, alpha (qemu) and hppa (qemu).
