yann@552: Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch yann@552: The gcc-3.x toolchains would contain all the targets by default. With gcc-4, yann@552: you have to actually list out the multilibs you want or you will end up with yann@552: just one when using targets like 'sh4-linux-gnu'. yann@552: yann@552: The resulting toolchain can't even build a kernel as the kernel needs to build yann@552: with the nofpu flag to be sure that no fpu ops are generated. yann@552: yann@552: Here we restore the gcc-3.x behavior; the additional overhead of building all yann@552: of these multilibs by default is negligible. yann@552: yann@552: http://bugs.gentoo.org/140205 yann@552: yann@552: diff -durN gcc-4.3.1.orig/gcc/config.gcc gcc-4.3.1/gcc/config.gcc yann@552: --- gcc-4.3.1.orig/gcc/config.gcc 2008-05-21 10:54:15.000000000 +0200 yann@552: +++ gcc-4.3.1/gcc/config.gcc 2008-06-10 14:58:06.000000000 +0200 yann@552: @@ -2278,7 +2278,7 @@ yann@552: if test x${sh_multilibs} = x ; then yann@552: case ${target} in yann@552: sh64-superh-linux* | \ yann@552: - sh[1234]*) sh_multilibs=${sh_cpu_target} ;; yann@552: + sh[1234]*) sh_multilibs=`cd ${srcdir}/config/sh ; echo t-mlib-sh[1-4]* | sed 's:t-mlib-sh:,m:g;s: ::g'` ;; yann@552: sh64* | sh5*) sh_multilibs=m5-32media,m5-32media-nofpu,m5-compact,m5-compact-nofpu,m5-64media,m5-64media-nofpu ;; yann@552: sh-superh-*) sh_multilibs=m4,m4-single,m4-single-only,m4-nofpu ;; yann@552: sh*-*-linux*) sh_multilibs=m1,m3e,m4 ;;
