From 4f48f31bbfc10697296ff004a92614d9249ca784 Mon Sep 17 00:00:00 2001 From: Alexandre Oliva Date: Thu, 22 Oct 2020 08:54:16 -0300 Subject: [PATCH] enable sincos optimization on mingw-w64 The sincos transformation does not take place on all platforms, because the libc_has_function target hook disables it by default. Current mingw-w64's math library supports sincos, sincosl and sincosf, in 32- and 64-bit modes. I suppose this has been this way for long. This patch enables the sincos optimization on this platform. for gcc/ChangeLog * config/i386/mingw-w64.h (TARGET_LIBC_HAS_FUNCTION): Enable sincos optimization. --- gcc/config/i386/mingw-w64.h | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/gcc/config/i386/mingw-w64.h b/gcc/config/i386/mingw-w64.h index 408e57cc0d7..0d0aa939996 100644 --- a/gcc/config/i386/mingw-w64.h +++ b/gcc/config/i386/mingw-w64.h @@ -98,3 +98,9 @@ along with GCC; see the file COPYING3.
