* cpphash.c (dump_definition): New function.
* cpphash.h: Prototype it.
* cpplib.c (handle_directive): Don't output anything here.
Streamline.
(pass_thru_directive): Take a length, not a pointer to the
end. All callers changed.
(do_define): Handle -dD, -dN, -g3 entirely here. Streamline.
(do_include): Handle -dI here.
(do_ident): Correct to match cccp.
(do_pragma): Copy the pragma through here.
(do_assert, do_unassert): Tidy.
* cppinit.c (cpp_finish): If -dM was specified, walk the macro
hash table and call dump_definition on all the entries.
* cppmain.c: cpp_finish may produce output.

1999-02-25 17:14 -0500 Zack Weinberg <zack@rabi.columbia.edu>
* cpphash.c (install): Rename to cpp_install, add cpp_reader*
first argument. All callers changed.
(hashtab): Removed.
(cpp_lookup, cpp_install): Change all refs to hashtab to
pfile->hashtab.
(cpp_hash_cleanup): Removed.
* cpphash.h: Adjust prototypes.
* cpplib.h (struct cpp_reader): Add hashtab pointer.
* cppinit.c (cpp_reader_init): Also allocate space for the
hashtab.
(cpp_cleanup): Delete all macros and free the hashtab.

* cpplib.c (special_symbol): Rewrite. Don't copy things
multiple times. Handle __STDC__ specially. T_CONST
indicates a constant /string/. Don't handle T_*_TYPE and
T_SPEC_DEFINED. Use cpp_buf_line_and_col instead of
adjust_position. Determine the file buffer only if needed.
(initialize_builtins): Handle __SIZE_TYPE__,
__PTRDIFF_TYPE__, __WCHAR_TYPE__, __USER_LABEL_PREFIX__, and
__REGISTER_PREFIX__ with T_CONST special hashtab entries.
Don't provide __OBJC__; the driver does that. Provide
__STDC_VERSION__, using T_CONST. Use T_STDC for
__STDC__. Give install the length of all symbols defined.
(eval_if_expression): Drop code to insert and remove the
"defined" special symbol.
* cpplib.h: Remove SELF_DIR_DUMMY (no longer used). Remove
T_*_TYPE and T_SPEC_DEFINED from enum node_type; add T_STDC.
* cpphash.c (install): Drop the `ivalue' parameter. Constify
the `value' parameter. All callers changed.
* cpphash.h (install): Change prototype to match.
(union hashval): Remove `ival' member.
* cppexp.c (cpp_lex): Handle `defined' here.

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.
From-SVN: r24325
* cppexp.c: When forcing unsigned comparisons, cast both sides
of the operation.
* cpphash.h: Move static declaration of hashtab[]...
* cpphash.c: ...here.
* cpplib.c: Cast difference of two pointers to size_t before
comparing it to size_t. Cast signed to unsigned
before comparing to size_t. (FIXME: struct argdata should use
unsigned buffer sizes.)
* cpplib.h (struct cpp_reader): Declare token_buffer_size as
unsigned int. (CPP_WRITTEN): Cast return value to size_t.
(CPP_RESERVE): Parenthesize N for evaluation order, cast to
size_t before comparison.
