a question regarding ifcvt.c

2007-05-21 Thread Tehila Meyzels
Hi, I'd like to get an explanation why ifcvt.c checks whether 1 of the 2 successors of the IF-header block has a stmt that exits from the loop? Why does it prevent the if-conversion? I'm referring to the following code: /* Nor exit the loop. */ if ((then_edge->flags & EDGE_LOOP_EXIT) ||

[RFC] Improve Tree-SSA if-conversion - convergence of efforts

Hi, I'd like to bring up on the list a discussion that a bunch of people (most of those CC-ed above) started at the GCC Summit: Lately, there were few efforts, that are not necessarily related to each other, but are all relevant to if-conversion. Each of them has its own restriction, like a spec
