From Anatol Pomozov Taken from Arch Linux arm-none-eabi-gcc package. Modified version of ARM patch https://gcc.gnu.org/ml/gcc-patches/2012-05/msg00083/enable-with-multilib-list-for-arm.patch This patch enables the use of the "--with-multilib-list" flag, when configuring GCC 6.2. It makes GCC 6 compatible with the configure flags used in the "gcc-arm-none-eabi-4.9" package. diff --git a/gcc/Makefile.in b/gcc/Makefile.in index 4ab7405..6e1ea2c 100644 --- a/gcc/Makefile.in +++ b/gcc/Makefile.in @@ -535,6 +535,7 @@ lang_opt_files=@lang_opt_files@ $(srcdir)/c-family/c.opt $(srcdir)/common.opt lang_specs_files=@lang_specs_files@ lang_tree_files=@lang_tree_files@ target_cpu_default=@target_cpu_default@ +with_multilib_list=@with_multilib_list@ OBJC_BOEHM_GC=@objc_boehm_gc@ extra_modes_file=@extra_modes_file@ extra_opt_files=@extra_opt_files@ diff --git a/gcc/config.gcc b/gcc/config.gcc index cb08a5c..7bded02 100644 --- a/gcc/config.gcc +++ b/gcc/config.gcc @@ -1072,7 +1072,7 @@ arm*-*-eabi* | arm*-*-symbianelf* | arm*-*-rtems*) case ${target} in arm*-*-eabi*) tm_file="$tm_file newlib-stdint.h" - tmake_file="${tmake_file} arm/t-bpabi" + tmake_file="${tmake_file} arm/t-bpabi arm/t-mlibs" use_gcc_stdint=wrap ;; arm*-*-rtems*) @@ -3684,42 +3684,6 @@ case "${target}" in exit 1 fi - # Add extra multilibs - if test "x$with_multilib_list" != x; then - arm_multilibs=`echo $with_multilib_list | sed -e 's/,/ /g'` - for arm_multilib in ${arm_multilibs}; do - case ${arm_multilib} in - aprofile) - # Note that arm/t-aprofile is a - # stand-alone make file fragment to be - # used only with itself.
