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. --- math/Versions | 3 +++ 1 file changed, 3 insertions(+) (limited to 'math/Versions') diff --git a/math/Versions b/math/Versions index d892c5f911..5b3c321490 100644 --- a/math/Versions +++ b/math/Versions @@ -590,4 +590,7 @@ libm { totalorderf128; totalordermagf128; } + GLIBC_2.32 { + exp10f; + } } -- cgit 1.4.1
