Following recent discussions of variable_size, this patch stops the C
front end from using the global pending_sizes list, instead using the
existing grokdeclarator support for tracking size expressions in the
one case where pending sizes were still needed. c_variable_size is
replaced by a call to save_expr. It way well be possible after this
patch to eliminate the pending_sizes list and associated functions and
the dont_save_pending_sizes_p field, but I don't plan to work on that.
Bootstrapped with no regressions on x86_64-unknown-linux-gnu. Are the
ObjC changes OK to commit?
2011-05-04 Joseph Myers <jos...@codesourcery.com>
* c-decl.c (finish_decl): Don't call get_pending_sizes.
(grokparm): Add parameter expr. Pass it to grokdeclarator.
(push_parm_decl): Add parameter expr. Pass it to grokdeclarator.
(c_variable_size): Remove.
(grokdeclarator): Use save_expr instead of c_variable_size. Don't
call put_pending_sizes.
(get_parm_info): Add parameter expr. Use it to set
arg_info->pending_sizes.
(store_parm_decls): Use arg_info->pending_sizes instead or calling
get_pending_sizes.
* c-parser.c (c_parser_parms_declarator): Update call to
c_parser_parms_list_declarator.
(c_parser_parms_list_declarator): Take parameter expr. Update
call to push_parm_decl. Update recursive call. Don't call
get_pending_sizes. Update calls to get_parm_info.
(c_parser_objc_method_definition): Update calls to
c_parser_objc_method_decl and objc_start_method_definition.
(c_parser_objc_methodproto): Update call to
c_parser_objc_method_decl.
(c_parser_objc_method_decl): Add parameter expr. Update call to
grokparm.
(c_parser_objc_try_catch_finally_statement): Update call to
grokparm.
* c-tree.h (struct c_arg_info.pending_sizes): Change to a tree.
(get_parm_info, grokparm, push_parm_decl): Update prototypes.
