Hi folks,
This patch adds support for netbsd/aarch64.
It would be nice to have it committed, please tell me if anything is
wrong.
Thanks.
Matthew Green <m...@eterna.com.au>
Maya Rashish <co...@sdf.org>
gcc:
* config.gcc (aarch64*-*-netbsd*): New target.
* config/aarch64/aarch64-netbsd.h: New file.
* config/aarch64/t-aarch64-netbsd: Likewise.
libgcc:
* config.host (aarch64*-*-netbsd*): New case.
