S/390: Add support for STT_GNU_IFUNC symbols. Add support for STT_GNU_IFUNC symbols and the new R_390_IRELATIVE relocation. Provide optimized version of memcpy, memset, and memcmp for z10 and z196. 2012-07-12 13:04:55 +02:00			`ifeq ($(subdir),string)`
S390: Refactor ifunc implementations and enable ifunc-test-framework. On s390 all ifunc resolvers were implemented in multiarch/ifunc-resolve.c. The resulting single object files has undefined references to all ifunc-functions. This patch introduces one multiarch/<func>.c file for each of memcpy, memcmp and memset with the function specific ifunc resolver. The different function implementations are now implemented in multiarch/<func>-s390x.S (moved from multiarch/<func>.S). The new multiarch/ifunc-resolve.h file contains the ifunc-resolver macro and other helper-macros. They are merged and are now used in common for 32/64bit. Therefore the __<func>_g5/__<func>_z900 functions were renamed to __<func>_default. This patch also enables testing the ifunc implementations by implementing the function __libc_ifunc_impl_list. It uses the helper-macros of ifunc-resolve.h.
