/* Despite the rest of the comments in this file, (FIXME-SOON),
|
2003-12-19 16:23:41 +01:00
|
|
|
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. */
