Two part question: 1) Does the control flow graph exist at the time we're emitting assembler instructions?
2) If so, how do I go at getting at the basic block info, specifically successor info, if the only thing I have is a rtx for a conditional jump insn? Okay, maybe a 3-part question. Given said jump insn handle, I'm trying to find out if either of the targets is a loop exit. Is there an easier way to do so than finding the successor arcs and seeing if either is flagged as a loop exit? Thanks, Pat
