[RFA,3/6] Comment out some unused overlay code
Commit Message
This patch comments out some unneeded initializations in overlay code
in symfile.c. Normally I would not comment out code like this, but
the uses of "size" in these functions are commented out. If you'd
prefer I could just delete the comments.

* symfile.c (simple_overlay_update_1): Comment out initialization
of "size".
(simple_overlay_update): Likewise.

I am inclined to remove these commented-out statements.
These statements were commented out in 1998, and nobody wanted to add
them back again since then,

* config/d10v/tm-d10v.h (CALL_DUMMY): Define as "{ 0 }".
(TARGET_READ_FP): Define to d10v_read_fp rather than d10v_read_sp.
(TARGET_WRITE_FP): Define to d10v_write_fp rather than d10v_write_sp.
(d10v_write_fp, d10v_read_fp): Add prototypes.
* symtab.c (decode_line_1): Remove assignment of sals[0].pc field.
* symfile.c (simple_overlay_update, simple_overlay_update_1):
Ignore the size of overlay sections. This check is redundant anyway.
