From: Jonathan Wakely <redi@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc r12-1784] libstdc++: Minor simd_math cleanups Date: Thu, 24 Jun 2021 13:34:33 +0000 (GMT) [thread overview] Message-ID: <20210624133433.9C596388801F@sourceware.org> (raw) https://gcc.gnu.org/g:62a989ea66e8b1d4c3ed4218c5115e050072711a commit r12-1784-g62a989ea66e8b1d4c3ed4218c5115e050072711a Author: Matthias Kretz <m.kretz@gsi.de> Date: Thu Jun 24 14:20:15 2021 +0100 libstdc++: Minor simd_math cleanups Signed-off-by: Matthias Kretz <m.kretz@gsi.de> libstdc++-v3/ChangeLog: * include/experimental/bits/simd_math.h: Undefine internal macros after use. (frexp): Move #if to a more sensible position and reformat preceding code. (logb): Call _SimdImpl::_S_logb for fixed_size instead of duplicating the code here. (modf): Simplify condition.
