Subject: [PATCH] Use 'location_hash' for 'gcc/diagnostic-spec.h:nowarn_map'
Instead of hard-coded '0'/'UINT_MAX', we now use the 'RESERVED_LOCATION_P'
values 'UNKNOWN_LOCATION'/'BUILTINS_LOCATION' as spare values for
'Empty'/'Deleted', and generally simplify the code.
gcc/
* diagnostic-spec.h (typedef xint_hash_t)
(typedef xint_hash_map_t): Replace with...
(typedef nowarn_map_t): ... this.
(nowarn_map): Adjust.
* diagnostic-spec.c (nowarn_map, suppress_warning_at): Likewise.
