Subject: sim: mn10300: delete unused exception/exited/debug state
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=96eaf29ec4df2f81be180cfeabdb9b26492e8264;p=binutils-gdb.git

sim: mn10300: delete unused exception/exited/debug state

The syscall path was the only code checking the custom exception state
after recent cleanups.  Once we change that to the common engine halt
function, we can delete that state entirely.

This also helps highlight some other dead code that we can cull.
