New Revision: 290186
URL: https://svnweb.freebsd.org/changeset/base/290186
Log:
Make truss work for CloudABI processes on aarch64.
This change copies over amd64-cloudabi64.c to aarch64-cloudabi.c and
adjusts it to fetch the proper registers on aarch64. To reduce the
amount of shared code, the errno conversion function is moved into a
separate source file.
