4102,Bit manipulation built-ins,uzytkownik,,"So far Haskell/GHC lacks more HL bit manipulation instructions which on many platform can be compiled to single instruction. Probably the good guide are those implemented in LLVM:

 - byte swap
 - population count
 - number of leading zeros
 - number of trailing zeros

All of them can be implemented in terms of Data.Bits - however not quite in efficient way (like looping over patterns).",feature request,new,normal,7.6.2,libraries/base,6.12.2,,,josefs@… gabriel@… dterei rrnewton@… wren@… johan.tibell@…,Unknown/Multiple,Unknown/Multiple,None/Unknown,,,,,
