------- Additional Comments From pinskia at gcc dot gnu dot org 2005-05-16 01:23 ------- Neither patches are fully complete and here is why, even though fold creates a new CALL_EXPR, we still need to copy the eh_region the function can throw so Steven's patch is not complete, we don't check for this right now but it is hard to test for (maybe). Second if we have a throw to a throw to a non throw function, we need to clean up the regions, so my patch in comment #12 is not complete.
I have a fix which I am writting up right now which combines the two problems, we have to change the interface for set_rhs and fold_stmt so they return if you need to removal of eh edges. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21399
