The reason we only exit with zero here is because the
semihosting API doesn't provide a way for the application
to report a non-zero exit code. In this case you're
distinguishing "application exit" from the other
failure reasons, which seems OK, though. I'm just
wary of patches trying to fix this issue because
in the past they've generally ignored the fact that
we're implementing a fixed API here and can't make
random additions to it just because they happen to work
with newlib or whatever.
Returning a negative exit code is bogus, though. You
probably just want
if (args == ADP_Stopped_ApplicationExit) {
code = EXIT_SUCCESS;
} else {
code = EXIT_FAILURE;
}
