* final.c (mark_symbol_ref_as_used): New helper function.
(output_operand): Instead of just looking inside MEMs for
SYMBOL_REFs, use new helper function and for_each_rtx.
* varasm.c (assemble_external): Move #ifndef ASM_OUTPUT_EXTERNAL
to after weak-handling. Don't mark decls with TREE_STATIC as weak.
Make head comment more general.
* config/darwin.c (machopic_output_indirection): Handle weak
references here, like in assemble_external.
