c-common.h (has_c_linkage): New interface.
* c-common.h (has_c_linkage): New interface.
* c-cppbuiltin.c: Include target.h.
(c_cpp_builtins): Define __PRAGMA_REDEFINE_EXTNAME and
__PRAGMA_EXTERN_PREFIX when appropriate.
* c-pragma.c: Include target.h.
Document clarified semantics of symbol-renaming #pragmas.
(handle_pragma_redefine_extname, handle_pragma_extern_prefix)
(maybe_apply_renaming_pragma): Rewrite according to clarified
semantics. Always recognize, but do not necessarily execute.
(init_pragma): Unconditionally register symbol-renaming pragmas.
* system.h: Poison HANDLE_PRAGMA_REDEFINE_EXTNAME
and HANDLE_PRAGMA_EXTERN_PREFIX.
* target.h (struct gcc_target): Add handle_pragma_redefine_extname
and handle_pragma_extern_prefix flags.
* target-def.h: Add defaults for TARGET_HANDLE_PRAGMA_REDEFINE_EXTNAME
and TARGET_HANDLE_PRAGMA_EXTERN_PREFIX.
* Makefile.in (c-pragma.o, c-cppbuiltin.o): Update dependencies.
* config/sol2.h: Define TARGET_HANDLE_PRAGMA_REDEFINE_EXTNAME,
not HANDLE_PRAGMA_REDEFINE_EXTNAME.
(TARGET_OS_CPP_BUILTINS): No need to define __PRAGMA_REDEFINE_EXTNAME.
(TRANSFER_FROM_TRAMPOLINE): Prototype mprotect.
* config/alpha/osf.h: Define TARGET_HANDLE_PRAGMA_EXTERN_PREFIX,
not HANDLE_PRAGMA_EXTERN_PREFIX.
(TARGET_OS_CPP_BUILTINS): No need to define __PRAGMA_EXTERN_PREFIX.
* doc/extend.texi (Solaris Pragmas, Tru64 Pragmas): Combine
into one section "Symbol-Renaming Pragmas"; clarify; document
adjusted semantics.
* builtins.c (expand_builtin): Do not issue error for a builtin
with no special case code and no DECL_ASSEMBLER_NAME; just do the
library call.
* c-decl.c (builtin_function): Don't call make_decl_rtl.
* c-objc-common.c (has_c_linkage): Stub implementation.
* cgraphunit.c (cgraph_expand_function)
(cgraph_remove_unreachable_nodes): Don't clear DECL_ARGUMENTS.
cp:
* cp-lang.c (has_c_linkage): Implement.
* cp-tree.h (set_mangled_name_for_decl): Don't prototype.
* decl.c (duplicate_decls): Use COPY_DECL_RTL.
(builtin_function_1): Don't call make_decl_rtl.
(build_cp_library_fn): Don't call set_mangled_name_for_decl.
(grokvardecl): Don't call mangle_decl.
* except.c (nothrow_libfn_p): Look at DECL_NAME, not
DECL_ASSEMBLER_NAME.
* method.c (set_mangled_name_for_decl): Delete.
* name-lookup.c (pushdecl): When a local extern shadows a
file-scope declaration of the same object, give both DECLs the
same DECL_UID.
* typeck.c (cxx_mark_addressable): Don't set TREE_ADDRESSABLE
on DECL_ASSEMBLER_NAME.
testsuite:
* g++.dg/expr/enum1.C, g++.dg/opt/const3.C: Declare abort with
extern "C".
* g++.dg/other/pragma-re-1.C: Add comments.
