The errors reported by check_attr_value weren't very helpful because
they always used the location of the define(_enum)_attr, even if the
error was in a define_insn. Also, the errors reported by
check_attr_test didn't say which attribute was faulty.
Although not technically a bug fix, it was really useful in writing
the patch for PR68432.
Tested on a variety of targets.
gcc/
* genattrtab.c (check_attr_test): Take an attr_desc instead of
an is_const flag. Put the file_location argument first.
Update recursive calls. Improve error messages.
(check_attr_value): Take a file location and use it instead
of attr->loc. Improve error messages. Update calls to
check_attr_test.
(check_defs): Update call to check_attr_value.
(make_canonical): Likewise.
(gen_attr): Likewise.
(main): Likewise.
(gen_insn_reserv): Update call to check_attr_test.
