The generic implementation uses either the compiler builts for ISA 2.03+ (which generates the frim instruction) or a generic implementation which uses FP only operations. The IFUNC organization for powerpc64 is also change to be enabled only for powerpc64 and not for powerpc64le. 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/fpu/trunc_to_integer.h (set_truncing_mode): Add TRUNC handling. * sysdeps/powerpc/fpu/s_trunc.c: New file. * sysdeps/powerpc/fpu/s_truncf.c: New file. * sysdeps/powerpc/powerpc32/fpu/s_trunc.S: Remove file. * sysdeps/powerpc/powerpc32/fpu/s_truncf.S: Likewise. * sysdep/powerpc/powepc32/power4/fpu/multiarch/s_trunc-power5+.S: Likewise. * sysdep/powerpc/powepc32/power4/fpu/multiarch/s_trunc-ppc32.S: Likewise. * sysdep/powerpc/powepc32/power4/fpu/multiarch/s_truncf-power5+.S: Likewise. * sysdep/powerpc/powepc32/power4/fpu/multiarch/s_truncf-ppc32.S: Likewise. * sysdep/powerpc/powepc32/power4/fpu/multiarch/s_trunc-power5+.c: New file. * sysdep/powerpc/powepc32/power4/fpu/multiarch/s_trunc-ppc32.c: Likewise. * sysdep/powerpc/powepc32/power4/fpu/multiarch/s_truncf-power5+.c: Likewise. * sysdep/powerpc/powepc32/power4/fpu/multiarch/s_truncf-ppc32.c: Likewise. * sysdep/powerpc/powerpc32/power5+/fpu/s_trunc.S: Remove file. * sysdep/powerpc/powerpc32/power5+/fpu/s_truncf.S: Likewise. * sysdep/powerpc/powerpc64/be/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_trunc-power5+, s_trunc-ppc64, s_truncf-power5+, and s_truncf-ppc64.
