instead, call md_show_usage. (parse_args): Use getopt_long_only. Take pointers to argc and argv. (main): Pass parse_args pointers. * as.h: Remove 3 variables that are redundant with flagseen. * as.c, messages.c: Change their users to use flagseen. Define getopt stuff. * tc.h: Update md_parse_option decl. Add md_show_usage decl. * config/tc-*.c: Add md_shortopts, md_longopts, md_longopts_size, md_show_usage. Change calling convention for md_parse_option. Remove md_parse_long_option. * config/tc-ns32k.c: Rename `struct option' to `struct ns32k_option'. * config/tc-i386.h: Don't define md_parse_option.

/*
|
|
* Despite the rest of the comments in this file, (FIXME-SOON),
|
|
* here is the current scheme for error messages etc:
|
|
*
|
|
* as_fatal() is used when gas is quite confused and
|
|
* continuing the assembly is pointless. In this case we
|
|
* exit immediately with error status.
|
|
*
|
|
* as_bad() is used to mark errors that result in what we
|
|
* presume to be a useless object file. Say, we ignored
|
|
* something that might have been vital. If we see any of
|
|
* these, assembly will continue to the end of the source,
|
|
* no object file will be produced, and we will terminate
|
|
* with error status. The new option, -Z, tells us to
|
|
* produce an object file anyway but we still exit with
|
|
* error status. The assumption here is that you don't want
|
|
* this object file but we could be wrong.
|
|
*
|
|
* as_warn() is used when we have an error from which we
|
|
* have a plausible error recovery. eg, masking the top
|
|
* bits of a constant that is longer than will fit in the
|
|
* destination. In this case we will continue to assemble
|
|
* the source, although we may have made a bad assumption,
|
|
* and we will produce an object file and return normal exit
|
|
* status (ie, no error). The new option -X tells us to
|
|
* treat all as_warn() errors as as_bad() errors. That is,
|
|
* no object file will be produced and we will exit with
|
|
* error status. The idea here is that we don't kill an
|
|
* entire make because of an error that we knew how to
|
|
* correct. On the other hand, sometimes you might want to
|
|
* stop the make at these points.
|
|
*
|
|
* as_tsktsk() is used when we see a minor error for which
|
|
* our error recovery action is almost certainly correct.
|
|
* In this case, we print a message and then assembly
|
|
* continues as though no error occurred.
