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 2014-11-28 Ramana Radhakrishnan <ramana.radhakrishnan@arm.com> * config/arm/t-aprofile (MULTILIB_MATCHES): New entry for -march=armv8-a+crc.
