TL;DR: Allow users to make one run:

$ ghc --make Test.hs TestPrim.hs test-prims.cmm -o t

instead of series:

$ ghc -c     test-prims.cmm
$ ghc --make test-prims.o Test.hs TestPrim.hs

The buildable example is located at: https://github.com/trofi/cmm-example

I'll just quote my email sent to ghc-devs@ a while ago:

> Hi guys!
> 
> Today I've tried to write a minimal [1] test case for ghc on ia64
> (it SIGSEGVs there).
> 
> The test case consists of a .cmm and some .hs modues.
> 
> I tried to build them in one run as:
>     $ ghc --make Test.hs TestPrim.hs test-prims.cmm -o t
>     ghc: cannot compile this file to desired target: test-prims.cmm
>     Usage: For basic information, try the `--help' option.
> 
> Thus had to use
>     ${GHC} -c     test-prims.cmm
>     ${GHC} --make test-prims.o Test.hs TestPrim.hs
> 
> What do you think of allowing to use .c, .cmm and similar
> files along with .hs files to make one-shot builds a bit easier?
> 
> If noone is opposed I'll fill a request on bugtracker.

> Thanks!
