This should be somewhat more efficient. * Makefile.in (scan-decls): Removed rule to make program. * patch-header.c (recognized_macro, recognized_extern, recognized_function): New functins, with logic moved out from read_scan_file, so they can be called by scan_decls. * patch-header (main): Read the original header file into a buffer (rather than reading it with stdio). This should be more efficient, partly because we can re-write it in place. (inf_skip_spaces, inf_read_upto, inf_scan_ident): New functions, based on skip_spaces, read_upto, and scan_ident in scan.c, but these read from the in-memory buffer mentioned above. * scan-types.sh: Don't check for sigset_t, since it can be a struct, whose name cannot be simplify replaced by its definition. * Makefile.in (deduced.h): Don't pass -nostdinc.

(compstmt): For `{ }', insert a .pushlevel and do all of the other stuff we need in every other compstmt situation, to generate proper debugging for such things and handle the binding levels properly for them. Thu Aug 19 18:24:25 1993 Mike Stump (mrs@cygnus.com) * cp-init.c (build_vec_delete): Wrap void COND_EXPR in NOP_EXPR, so that the backend does not abort when trying to use the void mode expression.

[Merged by bpk.] * cp-class.c ({pop,push}_nested_class): New functions to use instead of plain {push,pop}class. These functions will see to that static entities of enclosing classes will be visible. * cp-tree.h ({pop,push}_nested_class): Declare them. * cp-decl.h ({finish,start}_function): Use these new functions instead of plain {push,pop}class calls. (grokdeclarator): Ditto. * cp-decl2.c (build_push_scope): Ditto. * cp-class.c (popclass): Only call pop_class_decls if MODIFY is set. * cp-decl.c (start_decl): Maybe call pushdecl_class_level instead of pushdecl. This is used for nested types. (grokdeclarator): Remove the {push,pop}level calls around the indirect recursion occuring when groking class-local typedefs. Remove the error check of such typedefs hiding other fields in the same scope. Remove the pushdecl_class_level call since start_decl does the work now. Class scoping (and type value caching) redone. The new behaviour is triggered by NEW_CLASS_SCOPING being defined to 1. The old behavior is accomplished by defining it to the value 0. The entries below describes the effective changes when NEW_CLASS_SCOPING is set to non-zero. * cp-class.c (set_class_shadows): Add prototype. (previous_class_values): New variable. (pushclass): Adapted to not use previous_class_type & unuse_fields. Removed setting of IDENTIFIER_CLASS_VALUE. (popclass): Adapted to not use previous_class_type. Don't reset IDENTIFIER_CLASS_VALUE. Moved call of pop_class_decls. (maybe_push_cache_obstack): New function. * cp-decl.c (current_class_depth): Add extern decl. (previous_class_values): Add extern decl.

(set_nested_typename): Added comment. (pushtag): Don't call set_identifier_type_value. Leave out setting of IDENTIFIER_CLASS_VALUE. (adjust_type_value): Removed. (pushdecl): Don't call adjust_type_value. (pushdecl_class_level): Call push_class_level_binding. Set the type value if we're seeing a TYPE_DECL. (push_class_level_binding): New function whose guts came from pushdecl_class_level. (globalize_nested_type): See to that both the class_shadowed and type_shadowed lists in the binding stack gets updated correctly. Don't call set_identifier_type_value on the DECL_NESTED_TYPENAME. Clear DECL_CLASS_CONTEXT as well as DECL_CONTEXT. Install a correct IDENTIFIER_{CLASS,TYPE}_VALUE if needed. (grokdeclarator): Prefer pushdecl_class_level over pushtag when recording a nested typedef. (build_enumerator): Don't install a method-local enumerator into class scope. * cp-decl2.c (grokfield): Don't call set_identifier_type_value. * cp-search.c (closed_envelopes): New list containing information of what decls should be pushed when entering a class scope. (dfs_pushdecls): Build and maintain the closed_envelopes list instead of managing the IDENTIFIER_CLASS_VALUEs directly. (dfs_compress_decls): Adapted to recognize the envelopes dfs_pushdecls has installed in the IDENTIFIER_CLASS_VALUE slots. (push_class_decls): Tell overload_template_name to push the template decls into class scope instead of building a new level. Added code to open up the envelopes in closed_envelopes and install the class/type values in the class binding contour with proper shadowing. (dfs_popdecls): Removed. (pop_class_decls): Removed the actual decl-popping code, leaving just the obstack freeing pop_search_level call. The popping is automatically handled by poplevel now. * cp-tree.h (NEW_CLASS_SCOPING): A new macro constant defaulted to the value 1. (adjust_type_value): Prototype removed. (push_class_level_binding): Added prototype. Wed Jul 7 11:04:09 1993 Brendan Kehoe (brendan@lisa.cygnus.com) * cp-decl.c (pushdecl): When processing a typedef statement, generate a whole new ..._TYPE node.

Introduces a binary incompatability. * cp-tree.c (build_cplus_method_type): Mark the first argtype (the this pointer) as artificial. * cp-init.c (do_friend): Don't allow a friend of a class that's not yet been defined; instead, complain. Make sure we mark every decl that comes in as being a friend of something. * cp-decl2.c (grokclassfn): Mark the __in_chrg parameter as artificial. Don't mark it as readonly, and for destructors make sure the first arg in the arg_types chain has TREE_SIDE_EFFECTS set, so it's seen as artificial. (finish_vtable_vardecl): For dwarf debugging, make the vtable's VAR_DECL node be ignored. * cp-decl.c (redeclaration_error_message): Use comptypes to see if OLDDECL and NEWDECL have the same type. * cp-typeck.c (comptypes): Compare the main variants of the types, after we've checked the qualifiers that could have been used on them. * cp-call.c (EVIL_RETURN, QUAL_RETURN, TRIVIAL_RETURN, ZERO_RETURN): Rewrite definitions to not use do/while(0), to avoid bogus warnings on compilers that can't deal with a return inside it.

Tue Jul 6 13:00:44 1993 Brendan Kehoe (brendan@lisa.cygnus.com) * cp-decl.c (duplicate_decls): Set GIVE_ERROR so we know where the previous declaration was for empty parameter name list declarations. * cp-class.c (finish_struct): Clean up error message about anonymous classes. * cp-class.c (finish_struct): Don't play with TAIL when we're dealing with a TYPE_DECL of a RECORD_TYPE; the list continues on just fine, and TAIL is only used for managing FN_FIELDS. * cp-decl.c (pushlevel): Change cast to HOST_WIDE_INT. * cp-search.c (breadth_first_search): Likewise. Fri Jul 2 19:24:55 1993 Steve Chamberlain (sac@rtl.cygnus.com) * cp-method.c: Include "cp-class.h" Fri Jul 2 18:16:10 1993 Michael Tiemann (tiemann@blues.cygnus.com) * cp-call.c (build_overload_call_real): Don't look at a required template instantiation and a speculative template instantiation as two different functions if they are really the same function. Thu Jul 1 22:28:46 1993 Michael Tiemann (tiemann@blues.cygnus.com) * cp-tree.h: Don't include "cp-class.h" here. * cp-call.c, cp-cvt.c: Include it here instead.

(olddecl->olddecls) Thu Jul 1 18:34:12 1993 Brendan Kehoe (brendan@lisa.cygnus.com) New implementation of argument matching.

Thu Jul 1 17:54:44 1993 Mike Stump (mrs@cygnus.com) * cp-decl.c (duplicate_decls): Propagate some changes from C front-end. Conflicts with built-in functions are now only warnings.

Wed Jun 30 10:35:50 1993 Brendan Kehoe (brendan@lisa.cygnus.com) * cp-decl2.c (bad_specifiers): Moved to cp-decl.c. New args `inlinep' and `object' (old object renamed to type), so we can see where the thing was declared. Use error_with_decl instead of error. * cp-decl.c (grokdeclarator): Pass INLINEP and DECL down; move calls so we'll have a valid DECL to give it. * cp-tree.h (bad_specifiers): Deleted prototype. * cp-call.c (build_scoped_method_call): If it's a reference, work with the actual type. * cp-type2.c (build_scoped_ref): Likewise.

Tue Jun 29 12:44:48 1993 Brendan Kehoe (brendan@lisa.cygnus.com) * cp-typeck.c (mark_addressable): Don't complain about taking the address of an object with register storage class; it's legal in C++. * cp-typeck.c (convert_arguments): Only warn about passing an object through an ellipsis. * cp-parse.y (typed_declspecs): Make sure the TYPESPEC we hit upon is non-null. Tue Jun 29 11:58:03 1993 Tony Deigh (tonyd@bostech.com) * cp-decl.c (grokdeclarator): Look at the decl as a FUNCTION_TYPE before seeing if its TYPE_MAIN_VARIANT matches or it's a friend; this way, we can properly detect declaration of another class's methods inside another class.
