re PR c/15698 (no error in presence of broken builtin fn + K&R declaration)
PR c/15698
* c-tree.h (C_DECL_BUILTIN_PROTOTYPE): New.
* c-decl.c (current_function_prototype_built_in,
current_function_prototype_arg_types): New.
(merge_decls): Keep source location of prototype followed by
nonprototype declaration. Update C_DECL_BUILTIN_PROTOTYPE.
(builtin_function): Set C_DECL_BUILTIN_PROTOTYPE.
(start_function): Always set current_function_prototype_locus,
current_function_prototype_built_in and
current_function_prototype_arg_types. Check for external
prototype whether or not visible for external function and set
current_function_prototype_arg_types accordingly.
(store_parm_decls_oldstyle): Use
current_function_prototype_arg_types for checking old-style
definition against prototype. Give warnings only if
current_function_prototype_built_in).
testsuite:
* gcc.dg/builtins-30.c: Update expected messages.
* gcc.dg/pr15698-1.c, gcc.dg/pr15698-2.c, gcc.dg/pr15698-3.c,
gcc.dg/pr15698-4.c, gcc.dg/pr15698-5.c, gcc.dg/pr15698-6.c,
gcc.dg/pr15698-7.c, pr15698-8.c: New tests.
