| Series | Refactor IFUNC selection in C | expand |
I have tested this patchset natively on SPARC using GCC 4.9, 5, 6, 7, and 8 without any regression. Since it does not change any semantic regarding ifunc selection I am planning to push the mempcy and memset refactor next week so Patrick McGehearty can rebase its work on optimized M7 implementation.

This patchset is the continuation of two previous patchset [1][2][3][4] to convert ifunc implementation in assembly to C using GLIBC macros (which may use direct asm or GCC attributes depending of compiler support). No functional change is expected in generated symbols or ifunc selection, although some code reorganization was done in the case of ifunc selection also build the default variant at the same module. In this case a new file is created with 'generic' suffix. I also created a personal branch for this patchset on azanella/ifunc-c [5] [1] https://sourceware.org/ml/libc-alpha/2017-10/msg00578.html [2] https://sourceware.org/ml/libc-alpha/2017-10/msg00576.html
