- Authentication-results: sourceware.org; auth=none
Hi,
this patch adds support for cpus arm and aarch64 on Mach-O.
My first purpose was to use objdump on iOS binaries, so only
bfd and binutils are supported.
Pushed on master.
Tristan.
binutils: add support for arm-*-darwin and aarch64-*-darwin.
Currently only in bfd and binutils.
