Thanks; this does fix one crash on s390x, but doesn't fix the
pass57-frag crashes on s390.

Right, works fine on Solaris too.

Hi,
During the last weeks I have experimented a bit with the AVR back-end. IMO
there presently are two areas where it is worth to concentrating efforts on:
1.) cc0 -> CCmode transition
2.) splitting of HI- and SI-mode operations so that the RTL finally gets some
similarity with the actually exis
The condition-code re-use issue is the point, where, IMO, the link to the
subreg-lowering 2.) shows up. After, e.g., breaking down a HI mode "sub"
operation into two QI mode "sub" and "sub-with-carry"s at expand, I consider
it to be extremely difficult to make the mid-end smart enough to identif
I'm getting the following error messages when trying to run

Hi,
Kazu reported on the performance of tree-ssa from rebuild_jump_labels's
view in March last year: http://gcc.gnu.org/ml/gcc/2004-03/msg00659.html.
I decided to redo this little experiment on my collection of cc1-i files.
My results for today's CVS head at -O2 on amd64:
