This new addition, along with the aarch64 one, makes me wonder if it would be better to decompose the USE_* defined in multiple files so the architecture adds only the required ones (instead of copy/paste the whole file with the generic ones). Also for powerpc, maybe a future cleanup would to move the logic to select the builtin to math-use-builtins.h. Something like: #ifdef _ARCH_PWR5X # define USE_FLOOR_BUILTIN 1 # define USE_FLOORF_BUILTIN 1 #else # define USE_FLOOR_BUILTIN 0 # define USE_FLOORF_BUILTIN 0 #endif #define USE_FLOORL_BUILTIN 0 #define USE_FLOORF128_BUILTIN 0 Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> > --- > sysdeps/powerpc/fpu/math-use-builtins.h | 70 +++++++++++++++++++++++++ > sysdeps/powerpc/fpu/s_fma.c | 27 ---------- > sysdeps/powerpc/fpu/s_fmaf.c | 27 ---------- > 3 files changed, 70 insertions(+), 54 deletions(-) > create mode 100644 sysdeps/powerpc/fpu/math-use-builtins.h > delete mode 100644 sysdeps/powerpc/fpu/s_fma.c > delete mode 100644 sysdeps/powerpc/fpu/s_fmaf.c > > diff --git a/sysdeps/powerpc/fpu/math-use-builtins.h b/sysdeps/powerpc/fpu/math-use-builtins.h > new file mode 100644 > index 000000000000..9bdde66cf1de > --- /dev/null > +++ b/sysdeps/powerpc/fpu/math-use-builtins.h > @@ -0,0 +1,70 @@ > +/* Using math gcc builtins instead of generic implementation.
