I'm trying to generate LLVM bitcode for a static library with GHC, following other SO answers and guides online, I've arrived at:
FILE = lib
compile:
ghc -fllvm -keep-llvm-files -fforce-recomp -static -shared -flink-rts -fPIC $(FILE).hs
llvm-as $(FILE).ll -o $(FILE).bc
-- lib.hs
module Lib where
add x y = x + y
However running this gives:
$ ghc -fllvm -keep-llvm-files -fforce-recomp -static -shared -flink-rts -fPIC lib.hs
[1 of 1] Compiling Lib ( lib.hs, lib.o )
You are using an unsupported version of LLVM!
Currently only 9 to 13 is supported. System LLVM version: 13.0.0
We will try though...
Linking a.out ...
ld.lld: error: cant create dynamic relocation R_X86_64_32S against symbol:
stg_bh_upd_frame_info in readonly segment; recompile object files with -fPIC or pass '-Wl,-z,notext' to allow text relocations in the output

I should note that the GHC option to use -no-pie is enabled in settings file
