From 9818af7d436f7aa1bf5c635041cc5d08fec599b5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Storsj=C3=B6?= Date: Fri, 18 Jan 2019 09:31:10 +0200 Subject: qsimd: Fix compilation with trunk clang for mingw Current tip-of-tree clang (after Clang 8 was branched) added an intrinsic function __builtin_ia32_xgetbv, and added the following define that provides _xgetbv: #define _xgetbv(A) __builtin_ia32_xgetbv((long long)(A)) This fallback declaration of the _xgetbv function only is used in case the Q_OS_WIN branch of the #if/#elif below is used, if the #if (defined(Q_CC_GNU) && !defined(Q_CC_EMSCRIPTEN)) || defined(Q_CC_GHS) wasn't taken. I left out the !defined(Q_CC_EMSCRIPTEN) part as I believe Q_OS_WIN and Q_CC_EMSCRIPTEN are mutually exclusive.
