Re: [PATCH] Disable CSE skip-blocks



You mean operand selection?  Sure, but that's completely driven by the
equivalence tables.
No, I mean that, find_best_addr (which would go away if people cared to have a look at fwprop), fold_rtx (which does a lot even after fwprop), the 1000 lines of cse_insn, and so on.

This is not a negative commentary as it sounds -- it makes CSE is an *extremely* effective pass. The downside, of course, if that it's difficult to fully understand its implications.
