Subject: sim: common: add basic model assert
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ccd4b2953bb039e91b301a616c5f7c6f542b6b10;p=binutils-gdb.git

sim: common: add basic model assert

If the configured in default doesn't match a known value, throw an
assertion failure rather than segfaulting deeper down.
