From 218dad29e80f907ea77d830872770798b0249f67 Mon Sep 17 00:00:00 2001 From: Tulio Magno Quites Machado Filho Date: Wed, 13 Jun 2018 17:12:46 -0300 Subject: [PATCH] ldbl-128ibm-compat: Provide ieee128 symbols to narrow functions Move the narrow math aliasing macros into a new sysdep header file math-narrow-alias-float128.h. Then, provide an override header to supply the necessary changes to supply the *ieee128 aliases of these symbols. This adds ieee128 aliases for faddl, fdivl, fmull, fsubl, daddl, ddivl, dmull, dsubl. --- math/math-narrow.h | 15 +--------- sysdeps/generic/math-narrow-alias-float128.h | 32 ++++++++++++++++++++ sysdeps/ieee754/ldbl-128ibm-compat/Versions | 8 +++++ .../math-narrow-alias-float128.h | 34 ++++++++++++++++++++++ 4 files changed, 75 insertions(+), 14 deletions(-) create mode 100644 sysdeps/generic/math-narrow-alias-float128.h create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/math-narrow-alias-float128.h diff --git a/math/math-narrow.h b/math/math-narrow.h index ec22913..d8092c2 100644 --- a/math/math-narrow.h +++ b/math/math-narrow.h @@ -352,19 +352,6 @@ weak_alias (__f64 ## func ## f128, f64 ## func ## f128) \ weak_alias (__f64 ## func ## f128, f32x ## func ## f128) -#if __HAVE_FLOAT64X_LONG_DOUBLE -# define libm_alias_float32_float128(func) \ - libm_alias_float32_float128_main (func) -# define libm_alias_float64_float128(func) \ - libm_alias_float64_float128_main (func) -#else -# define libm_alias_float32_float128(func) \ - libm_alias_float32_float128_main (func) \ - weak_alias (__f32 ## func ## f128, f32 ## func ## f64x) -# define libm_alias_float64_float128(func) \ - libm_alias_float64_float128_main (func) \ - weak_alias (__f64 ## func ## f128, f64 ## func ## f64x) \ - weak_alias (__f64 ## func ## f128, f32x ## func ## f64x) -#endif +#include #endif /* math-narrow.h. */ diff --git a/sysdeps/generic/math-narrow-alias-float128.h b/sysdeps/generic/math-narrow-alias-float128.h new file mode 100644 index 0000000..4788708 --- /dev/null +++ b/sysdeps/generic/math-narrow-alias-float128.h @@ -0,0 +1,32 @@ +/* Helper macros for functions returning a narrower type.
