  • Ticket #4101 – Description

    initial v1  
    11Examining the core generated by ghc with -O2 on a numerical code, I saw things like : 
    2  
     2{{{ 
    33case GHC.Prim.<## x_aB9 (GHC.Prim.**## 2.0 -1021.0) of _  {... 
    4  
     4}}} 
    55This code being executed each time my code performs an addition ! GHC does not seem to unfold the constants right with at least **##. By the way, it should definitely be possible to specify a Double# constant in hexadecimal.
