From be668a8d782ab6bf363d4cdd7086295b5eebb8ea Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 8 Apr 2020 19:51:44 -0300 Subject: New exp10f version without SVID compat wrapper This patch changes the exp10f error handling semantics to only set errno according to POSIX rules. New symbol version is introduced at GLIBC_2.32. The old wrappers are kept for compat symbols. There are some outliers that need special handling: - ia64 provides an optimized implementation of exp10f that uses ia64 specific routines to set SVID compatibility. The new symbol version is aliased to the exp10f one. - m68k also provides an optimized implementation, and the new version uses it instead of the sysdeps/ieee754/flt32 one. - riscv and csky uses the generic template implementation that does not provide SVID support. For both cases a new exp10f version is not added, but rather the symbols version of the generic sysdeps/ieee754/flt32 is adjusted instead. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu. --- sysdeps/m68k/m680x0/fpu/e_exp10f.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'sysdeps/m68k/m680x0/fpu/e_exp10f.c') diff --git a/sysdeps/m68k/m680x0/fpu/e_exp10f.c b/sysdeps/m68k/m680x0/fpu/e_exp10f.c index f58fddd8a6..0d03f00e06 100644 --- a/sysdeps/m68k/m680x0/fpu/e_exp10f.c +++ b/sysdeps/m68k/m680x0/fpu/e_exp10f.c @@ -1,3 +1,8 @@ +#include #define FUNC __ieee754_exp10f #define FUNC_FINITE __exp10f #include +strong_alias (__ieee754_exp10f, __exp10f) +libm_alias_finite (__ieee754_exp10f, __exp10f) +versioned_symbol (libm, __exp10f, exp10f, GLIBC_2_32); +libm_alias_float_other (__ieee754_exp10, exp10) -- cgit 1.4.1
