powerpc: Use generic e_expf
Generic implementation is faster on both power8 and power9: POWER9: - sysdeps/ieee754/flt-32/e_expf.c "expf": { "workload-spec2017.wrf": { "duration": 5.1236e+09, "iterations": 7.53344e+08, "reciprocal-throughput": 5.9436, "latency": 7.65869, "max-throughput": 1.68248e+08, "min-throughput": 1.30571e+08 } } - sysdeps/powerpc/powerpc64/power8/fpu/e_expf.S "expf": { "workload-spec2017.wrf": { "duration": 5.14429e+09, "iterations": 5.29248e+08, "reciprocal-throughput": 8.05372, "latency": 11.3863, "max-throughput": 1.24166e+08, "min-throughput": 8.78249e+07 } } Checked on powerpc-linux-gnu (built without --with-cpu, with --with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch), powerpc64-linux-gnu (built without --with-cp and with --with-cpu=power5+ and --disable-multi-arch). * sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile (libm-sysdep_routines): Remove e_expf-power8 and expf-ppc64. * sysdeps/powerpc/powerpc64/fpu/multiarch/e_expf-power8.S: Remove file. * sysdeps/powerpc/powerpc64/fpu/multiarch/e_expf-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/e_expf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/w_expf.c: Likewise. * sysdeps/powerpc/powerpc64/power8/fpu/e_expf.S: Likewise. * sysdeps/powerpc/powerpc64/power8/fpu/w_expf.c: Likewise.
