From 3d81e50ab3d715a5e347fcdbd3b16272cff1f2bd Mon Sep 17 00:00:00 2001 From: Ken Steele Date: Fri, 22 Nov 2013 12:54:32 -0500 Subject: [PATCH] Check for compiler for -march=native support Check all compilers to see if they support the -march=native flags, rather than assuming gcc 4.2 or later does. Tile GCC doesn't currently support it, so not checking break Tile compiles. --- configure.ac | 20 -------------------- 1 file changed, 20 deletions(-) diff --git a/configure.ac b/configure.ac index 4b394c6907..3556641573 100644 --- a/configure.ac +++ b/configure.ac @@ -305,7 +305,6 @@ AC_ARG_ENABLE(gccmarch_native, AS_HELP_STRING([--enable-gccmarch-native], [Enable gcc march=native gcc 4.2 and later only]),,[enable_gccmarch_native=yes]) AS_IF([test "x$enable_gccmarch_native" = "xyes"], [ - if test `basename $CC` = "clang"; then OFLAGS="$CFLAGS" CFLAGS="$CFLAGS -march=native" AC_MSG_CHECKING([checking if $CC supports -march=native]) @@ -320,25 +319,6 @@ enable_gccmarch_native=no ] ) - fi - if test `basename $CC` = "gcc"; then - case $host in - *darwin*|*Darwin*) - if test "$gccvernum" -ge "403"; then - dnl gcc 4.3 or later - CFLAGS="$CFLAGS -march=native" - else - enable_gccmarch_native=no - fi - ;; - *) - if test "$gccvernum" -ge "402"; then - dnl gcc 4.2 or later - CFLAGS="$CFLAGS -march=native" - fi - ;; - esac - fi ]) # options -- 2.47.2
