This backend is no longer maintained and was supposed to have been
deleted as of GCC 15, but since it is still part of GCC and documented
in the manual, I have gone ahead and fixed up its options
documentation for consistency with other active targets.
gcc/ChangeLog
PR other/122243
* config/ia64/ia64.opt (msched-prefer-data-spec-insns): Mark as
explicitly "Undocumented".
(msched-prefer-non-control-spec-insns): Likewise.
* doc/invoke.texi (Option Summary) <IA-64 Options>: Remove
explicitly undocumented and redundant mno- forms from the list.
(IA-64 Options): Remove documentation for already-deleted option
-mfused-add and the two explicitly undocumented options. Add
@opindex for negative forms and explicitly list the -mno-forms
of options that are enabled by default.
