From c37c08738260e267764b6d6a8d4469eaa1e6568a Mon Sep 17 00:00:00 2001 From: Ben Wagner Date: Thu, 15 Jul 2021 11:33:16 -0400 Subject: [PATCH] Guard inclusion of emmintrin.h Guard inclusion of emmintrin.h with "#ifdef __SSE2__". The gcc version of this header, xmmintrin.h, and mmintrin.h check that the appropriate defines are set before defining anything (are internally guarded). However the clang versions of these includes are not internally guarded. As a result of this, externally guard the inclusion of these headers. --- src/smooth/ftgrays.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/smooth/ftgrays.c b/src/smooth/ftgrays.c index 7158cd21c..5e04ff41b 100644 --- a/src/smooth/ftgrays.c +++ b/src/smooth/ftgrays.c @@ -1009,7 +1009,9 @@ typedef ptrdiff_t FT_PtrDist; #if BEZIER_USE_DDA +#ifdef __SSE2__ #include +#endif static void gray_render_conic( RAS_ARG_ const FT_Vector* control,
