gensupport.h (compute_test_codes): Declare.
gcc/
* gensupport.h (compute_test_codes): Declare.
* gensupport.c (compute_predicate_codes): Rename to...
(compute_test_codes): ...this. Generalize error message.
(process_define_predicate): Update accordingly.
* genpreds.c (compute_maybe_allows): Delete.
(add_constraint): Use compute_test_codes to determine whether
something can accept a SUBREG, REG or MEM.
