Hi Zdenek, all,
I'm running into some troubles with an if-conversion pass that runs
after reload, where we have to avoid lifting insns across a loop
exit edge into a loop. ifcvt.c uses flow_loops_find to find loops
and mark all loop exit edges:
if ((! targetm.cannot_modify_jumps_p ())
&&

Hi Zdenek, all,
Is this something that could be easily fixed? E.g. can we make it
that flow_loops_find only performs transformations if asked to (by
adding a function argument for that)?
Why not have a flow_canonicalize_loops that does
