Joseph Myers 2d9193f2f5 Use generic __ifunc for SPARC. ... glibc fails to build with GCC mainline for SPARC because of the use of manually-created IFUNCs, which fail the tests of compatibility of function alias types. This patch changes sparc-ifunc.h to use the generic __ifunc in defining sparc_libm_ifunc. The generic __ifunc can use the GCC ifunc attribute when available, so ensuring type-correctness as well as better debug info than when setting symbol types in asm statements. Note that for this to fix the build with GCC mainline the GCC patch <https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01779.html>, or building GCC with --enable-gnu-indirect-function, is also needed. Tested (compilation only) with build-many-glibcs.py (sparc64-linux-gnu and sparcv9-linux-gnu, with GCC 8 with the above patch, and also with GCC 7). * sysdeps/sparc/sparc-ifunc.h [!__ASSEMBLER__] (sparc_libm_ifunc): Define using __ifunc.		2017-09-26 19:49:33 +00:00
