- * 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.

- ERRORS
-
- JF: this is now bogus. We now print more standard error messages
- that try to look like everyone else's.
-
- We print the error message 1st, beginning in column 1.
- All ancillary info starts in column 2 on lines after the
- key error text.
- We try to print a location in logical and physical file
- just after the main error text.
- Caller then prints any appendices after that, begining all
- lines with at least 1 space.
-
- Optionally, we may die.
- There is no need for a trailing '\n' in your error text format
- because we supply one.
-
- as_warn(fmt,args) Like fprintf(stderr,fmt,args) but also call errwhere().
-
- as_fatal(fmt,args) Like as_warn() but exit with a fatal status.
