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