Hi,
An internal user reported that -march=armv8-a+crc wasn't allowing the
driver to pick up the right multilib for an arm-none-eabi toolchain
configured with --with-multilib-list=aprofile.
Without this patch on arm-none-eabi with
--with-multilib-list=aprofile prints.
$)./xgcc -S -O2 -march=armv8-a+crc -mfpu=neon -mfloat-abi=softfp
-print-multi-directory /tmp/tst.c
.
$) with this patch
$>./xgcc -S -O2 -march=armv8-a+crc -mfpu=neon -mfloat-abi=softfp
-print-multi-directory /tmp/tst.c
v7-a/simdv1/softfp
Applied to trunk after simple cross build and test on arm-none-eabi. I
intend to backport the same to the 4.9 branch as the issue exists there
too and this is just in the configury and build of the baremetal toolchain.
regards
Ramana
