is undocumented.  This is a regression in 3.5.
Comment 1 Andrew Pinski 2004-07-07 14:54:14 UTC 
Confirmed and not just a regression in 3.5.0 but also on the 3.4 branch too.
Comment 2 Mark Mitchell 2004-08-29 19:09:45 UTC 
Postponed until GCC 3.4.3.

Comment 6 Andrew Pinski 2004-10-06 01:06:59 UTC 
Fixed.
Comment 7 Eric Botcazou 2005-05-30 14:33:06 UTC 
Alan, am I mistaken or did you document on the 3.4 branch something that is only
in 4.x?  AFAICS PR bootstrap/14992 has been solved differently on that branch:

	PR bootstrap/14992
	* configure.ac: Define HAVE_LD_AS_NEEDED only for linux.
	* configure: Regenerate.
	* gcc.c (init_gcc_specs): Revert earlier change.
Comment 8 Alan Modra 2005-05-30 23:19:07 UTC 
Yes.  s/USE_LD_AS_NEEDED/HAVE_LD_AS_NEEDED/ will make the doc right on 3.4
Comment 9 Eric Botcazou 2005-05-31 04:17:29 UTC 
> Yes.  s/USE_LD_AS_NEEDED/HAVE_LD_AS_NEEDED/ will make the doc right on 3.4

Sort of.  HAVE_LD_AS_NEEDED is not a target macro per se.
