Hello Abhiroop!

LLVM backend seems to choke on this still:

ghc-stage1: panic! (the 'impossible' happened) (GHC version 8.7.20181118 for x86_64-unknown-linux): LlvmCodeGen.CodeGen.cmmPrimOpFunctions: MO_S_QuotRem W16 not supported here

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug

Cheers,

Gabor
