But are you saying MachO will not work as well as ELF? Thanks for the patch Andrew, that will have to be my plan B in this case.

I'm working with LLVM 3.1, but I don't think much has changed in trunk.

Hi Verena, Windows + MachO is likely to run into lots of problems once you start passing in non-trivial code. The relocation model is very tied to Darwin. I believe some folks doing JIT on Windows have had some success w/ ELF. Hopefully someone more familiar with the specifics of that will chime in. -Jim...

This means I'm replicating the passes and doing code gen twice, basically. Any advice would be much appreciated!

Hi Verena, I think that we can count the number of instructions with "-stats" command line option. As you mentioned, this option uses Statistic class like "STATISTIC(EmittedInsts, "Number of machine instrs printed");" I don't know exactly about parallel code generation env...

Hi Stepan, These are quite interesting numbers. Thanks for running this experiment! Do you have some numbers on the difference of memory consumption and compile time (at -O0 and -O2) with and without case ranges? I think we need to see those numbers before we can decide wether it's interesting to commit to case ranges or not. Thanks, Nuno Quoting Stepan Dyatkovskiy <stpworld at

Hi all! I collected some statistics for SwitchInst, based on our test-suite. I found that efficiency is meaningful for parser-like applications only, about 15-20% of cases may be reduced (see top 10 items in Raw sheet of attached .xls file). Below some numbers. Total number of cases in all test-suite -- 11835. Clusters possible to make -- 503 Clusters with size (H - L) + 1
