I just recently noticed that GHC in ArchLinux is compiled with the LLVM backend support: $ ghc --info |grep llvm ,("Have llvm code generator","YES") However, can it be made to work on Arch? $ cat Mains.hs module Main where main = return () $ ghc --make -fllvm Mains.hs [1 of 1] Compiling Main ( Mains.hs, Mains.o ) opt: /tmp/ghc14739_0/ghc14739_0.ll:7:78: error: argument attributes invalid in function type @Main_main_closure = global %Main_main_closure_struct <{i64 ptrtoint (void (i64* noalias nocapture,i64* noalias nocapture,i64* noalias nocapture,i64 ,i64 ,i64 ,i64,i64 ,i64 ,i64 ,float ,float ,float ,float ,double ,double )* @Main_main_info to i64),i64 0,i64 0,i64 0}> /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus@therning.org jabber: magnus@therning.org twitter: magthe http://therning.org/magnus
