These changes are part of
commit r13-2361-g7e0db0cdf01e9c885a29cb37415f5bc00d90c029
"STABS: remove -gstabs and -gxcoff functionality". What this does is
remove these identifiers from "poisoning":
/* As the last action in this file, we poison the identifiers that
shouldn't be used.
[...]
/* Other obsolete target macros, or macros that used to be in target
headers and were not used, and may be obsolete or may never have
been used. */
#pragma GCC poison [...]
Shouldn't these identifiers actually stay (so that any accidental future
use gets flagged, as I understand this machinery), and instead more
identifiers be added potentially: those where their definition/use got
removed with "STABS: remove -gstabs and -gxcoff functionality"? (I've
not checked.)
Well, the identifiers are not used any longer, so I don't think we should
poison them. Or do I miss something?
