------- Comment #27 from jakub at gcc dot gnu dot org 2007-12-13 17:34 -------
First of all I wonder what's the point of the PA ASM_OUTPUT_EXTERNAL_REAL vs.
ASM_OUTPUT_EXTERNAL hacks. The middle-end already does the deferring itself,
see
assemble_external/process_pending_assemble_externals/assemble_external_real.
The only place where ASM_OUTPUT_EXTERNAL is invoked is during
process_pending_assemble_externals, i.e. right before targetm.asm_out.file_end
(well, there is also output of IDENT_ASM_OP, but that isn't relevant).
So, PA buffers the externals once again, from the
process_pending_assemble_externals call to the immediately following
file_end.
