canonical form loops
Hello,
Quick question to see if I haven't missed anything: I would like convert counting down loops, i.e. loops with a constant -1 step value, to counting up loops, because the vectoriser is able to better deal with these loops (see e.g. D76838 that I was discussing today with Ayal). It looks like LoopSimplifyCFG and IndVarSimplify don't do this. So was just curious if I haven't missed anything here or in another pass I haven't yet considered. I was perhaps also expecting this to be the canonical form of loops, but couldn'...
