- Subject: Duplicating immediate predecessor of EXIT_BLOCK
I'm interested in duplicating the immediate predecessor basic block of the
EXIT_BLOCK, but this makes the EXIT_BLOCK have 2 predecessors which isn't
allowed. Can someone give me some guidances as to how I can insert a
bogus block between the two to allow the duplication?
Thanks,
Chad Rosier
