From: Matthias Kretz <mkretz@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc r13-6299] libstdc++: Fix simd build failure on clang Date: Thu, 23 Feb 2023 14:04:02 +0000 (GMT) [thread overview] Message-ID: <20230223140402.82334385B51C@sourceware.org> (raw) https://gcc.gnu.org/g:92c47b15d5af3e7f93d11ad69a45b6d1cb8661c5 commit r13-6299-g92c47b15d5af3e7f93d11ad69a45b6d1cb8661c5 Author: Matthias Kretz <m.kretz@gsi.de> Date: Mon Feb 20 11:13:44 2023 +0100 libstdc++: Fix simd build failure on clang Clang does not support __attribute__ on lambdas. Therefore, only set _GLIBCXX_SIMD_ALWAYS_INLINE_LAMBDA if __clang__ is not defined.
