Hi, I found these: https://github.com/ghc/ghc/blob/5f3c5384df59717ca8013c5df8d1f65692867825/includes/rts/Constants.h#L194
They go only 0-14, so there's some long chains of branches and stuff in hot paths that could be cleaned up into single &-masked branches by changing these into a set of flags. And then I saw these: https://github.com/ghc/ghc/blob/master/libraries/base/GHC/Conc/Sync.lhs#L483 Where does 16 and 17 come from -- I couldn't find them in the header files anywhere? Kyle
