From: Giuliano Belinassi <giulianob@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc/devel/autopar_devel] Check for more missing math decls on vxworks. Date: Sat, 22 Aug 2020 21:46:25 +0000 (GMT) [thread overview] Message-ID: <20200822214625.6085E385DC17@sourceware.org> (raw) https://gcc.gnu.org/g:55b07f55154eba05a53859960b9d33528eea56e5 commit 55b07f55154eba05a53859960b9d33528eea56e5 Author: Douglas B Rupp <douglas.b.rupp@gmail.com> Date: Sun May 31 13:25:28 2020 -0700 Check for more missing math decls on vxworks. Use the GLIBCXX_CHECK_MATH_DECL macro to check for the full list of vxworks math decls. libstdc++-v3/ChangeLog * crossconfig.m4 (<*-vxworks>): Check for more math decls. * configure: Rebuild.
