cpphash.h (union hash_value): Remove `keydef' member, add a `struct hashnode *aschain' member for #assert.
1998-12-15 Zack Weinberg <zack@rabi.phys.columbia.edu>
* cpphash.h (union hash_value): Remove `keydef' member, add a
`struct hashnode *aschain' member for #assert.
* cpplib.c (struct tokenlist_list, struct
assertion_hashnode): Delete structure definitions.
(assertion_install, assertion_lookup, delete_assertion,
check_assertion, compare_token_lists, reverse_token_list,
read_token_list, free_token_list): Delete functions.
(parse_assertion): New function.
(cpp_cleanup): Don't destroy the assertion_hashtable.
(do_assert): Gut and rewrite. #assert foo (bar) places
entries for `#foo' and `#foo(bar)' in the macro hash table,
type T_ASSERT. The value union's `aschain' member is used
to chain all answers for a given predicate together.
(do_unassert): Also rewritten. Take an un-asserted
answer off the chain from its predicate and call
delete_macro on the hashnode, or walk a predicate chain
calling delete_macro on all the entries.
(cpp_read_check_assertion): Simply call parse_assertion to
get the canonical assertion name, and look that up in the
hash table.
* cpplib.h (ASSERTION_HASHNODE,ASSERTION_HASHSIZE,assertion_hashtab):
Removed.
* cpphash.c (install): Use bcopy instead of an explicit loop
to copy the macro name.
* cppexp.c (cpp_lex): Convert the result of
cpp_read_check_assertion to a `struct operation' directly;
don't go through parse_number.
