Daniel Jacobowitz:
This sounds a bit similar to Nathan Froyd's recent work:
Note that this is PR 29944.
For ARCompact, doloop loops in particular were interesting to
optimize, which is why I have a patch to loop-doloop.c in
svn://gcc.gnu.org/svn/gcc/branches/arc-4_4-branch :
2009-02-24 J"orn Rennecke <joern.renne...@arc.com>
* loop-doloop.c (doloop_valid_p): Rename to:
(validize_doloop). Try to fix up loops with conditons for infinite
looping by enclosing them in an outer loop.
Changed caller.
(add_test): Add new parameter edgep. Changed caller.
