[narrowing circulation somewhat] | Thanks. Simon PJ also mentioned that (undocumented?) flag, but I | must be using it wrong, because | | ghc --make -O2 Main.hs -dsuppress-uniques -ddump-simpl >simpl-slow | | still gives me plenty of _labels in the output (6.9.20080514). How is | this flag supposed to be used?
Ironically, it'll work for every pass *except* the very last one, which is what is dumped by -ddump-simpl! The final pass (called Core Tidy) gives each identifier a canonical name, like x1, x2 etc, as part of its OccName that that is printed in the .hi file, not just as a separate Unique embedded in the Name. Once that is done, it's harder to suppress the "1" etc, because they are part of the OccName itself. I could make -dsuppress-uniques suppress the tidying that CoreTidy does, but that means it'll generate utterly bogus code, with clashes of names in the .o files etc. So it'd be fine for debugging *one* module, but no good if you wanted to compile several. I'm not sure how best to solve this. Meanwhile -dverbose-core2core will show you the other passes.
