From ae45cf84afba7c6c34c6ebec4598901ed78c28f1 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 15 Mar 2019 20:37:23 +0000 Subject: [PATCH] powerpc: trunc/truncf refactor This patches consolidates all the powerpc trunc{f} implementations on the generic sysdeps/powerpc/fpu/s_trunc{f}. 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 (since minium ISA of 2.08 does not require the fallback generic implementation). 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_fenv_mode): Add TRUNC handling. (round_mode): Add definition for TRUNC. * 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.
