|
||||
Merge with latest FSF versions of these files.
|
||||
|
||||
* stab.gnu.h: Add LAST_UNUSED_STAB_CODE.
|
||||
* stab.def: Update to GPL2. Move N_WARNING out, since not a
|
||||
debug symbol. Change comments, and reorder table to numeric
|
||||
order. Update final table comment.
|
||||
(N_DSLINE, N_BSLINE): Renumber from 0x66 and 0x68, to 0x46 and 0x48.
|
||||
|
||||
Fri Aug 23 01:54:23 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||||
|
||||
* a.out.gnu.h, a.out.sun4.h: Make SEGMENT_SIZE able to depend
|
||||
on the particular a.out being examined.
|
||||
* a.out.sun4.h: Define segment sizes for Sun-3's and Sun-4's.
|
||||
* FIXME: a.out.gnu.h is almost obsolete.
|
||||
* FIXME: a.out.sun4.h should be renamed a.out.sun.h now.
|
||||
|
||||
Wed Aug 21 20:32:13 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||||
|
||||
* Start a ChangeLog for the includes directory.
|
||||
|
||||
* a.out.gnu.h (N_FN): Fix value -- was 15, should be 0x1E.
|
||||
* stab.def: Update allocation table in comments at end,
|
||||
to reflect reality as I know it.
