AFAICT, assemble_external () [no longer?] emits any assembly nor does it call
DECL_ASSEMBLER_NAME:
it seems to check for a weak function and add that to the weak functions list
and then (if the target defines ASM_OUTPUT_EXTERNAL) adds the decl to the
pending list which is output from assemble_pending_externals () called from
toplev.c.
varasm (assemble variable) says:
/* Normally no need to say anything here for external references,
since assemble_external is called by the language-specific code
when a declaration is first seen. */
if (DECL_EXTERNAL (decl))
return;
I would imagine that if this were replaced by:
if (DECL_EXTERNAL (decl))
{
assemble_external (decl);
return;
}
we should be able to remove the calls in ObjC (I'll try this later).
OTOH, I wonder if we have a case of a solved problem with the bug left
open....?
[BTW, I also have checking the status of 24777 on my TODO.]
