Description Andi Kleen 2009-10-05 14:31:28 UTC 
e.g. when -fwhole-program should be specified, at compile or at line time
and that it applies to the object files

I figured it out using the source and #gcc, but it would be better in
the texinfo file.
Comment 1 Richard Biener 2009-10-05 14:37:56 UTC 
Confirmed.

Draft patch at http://gcc.gnu.org/ml/gcc-patches/2009-10/msg00300.html,
has room for improvements.

Andi, is the current wording sufficient or is something missing/unclear?
