 == System and compiler version ==

 System: Raspberry Pi 2 running Raspbian Jessie (September 2016 release);
 LLVM 3.7 installed.

 GHC: GHC 8.0.1 ARMv7 binary downloaded from GHC webpage
 (ghc-8.0.1-armv7-deb8-linux.tar.xz).

 GCC version 4.9.2 (Raspbian 4.9.2-10)

 == Details ==

 GHCi works perfectly, however 'ghc --make' does not work at all. The
 following minimal test program fails to compile:

 {{{#!hs
 main :: IO ()
 main = putStrLn "Hello!"
 }}}

 Here are the first few lines of the compiler output:

 {{{
 pi at raspberrypi:~/haskell/test $ ~/opt/ghc-8.0.1/bin/ghc --make test.hs
 [1 of 1] Compiling Main             ( test.hs, test.o )
 /tmp/ghc2094_0/ghc_6.s: Assembler messages:

 /tmp/ghc2094_0/ghc_6.s:40:0: error:
      Error: selected processor does not support ARM mode `movw
 r7,:lower16:stg_bh_upd_frame_info'
 }}}

 See attachment for full compiler output with '-v'.
