options, rather than silently exiting unsuccessfully. (N.B. the code
in gas/as.c handling an 0 return from md_parse_option appears to be
broken, but I'm not sure what the right fix is. Unless the
expectation is that md_parse_option will have issued a diagnostic if
it returns 0, which is not what tc-ia64.c was doing.)
I think the docs are wrong in this regard. I too implemented an
md_parse_option that produced the same silent failure mode of tc-ia64.c,
by reading what internals.texi said.
I'm not sure whether it is the docs, or as.c which needs changing.
