Actually probably not debris leftover but needed code. I just removed -x
assembler-with-cpp and got this:
gcc: ghc/Main.hs: linker input file unused because linking not done
so we definitely need some -x to set language even for GNU C. Tested
also with old 3.4.x. From langs available, assembler-with-cpp looks like
the best option unfortunately...

Oooooo. Then it's possibly debris leftover from Austin's initial clang
compatibility work predating the improvements via the settings file work.
I'm Afk right now, but that probably can be safely removed from ghc,
especially since the configure script for clang cpp adds that anyways
now I think? I might be wrong though.

why should this flag be passed to cpp when invoked on HS files?
It'd be
easy to expose another field in the settings file for this other
invokecation.. though i should look more closely at the use site
before
opinining :)
Hmm, isn't doCpp function what's invoked when cpp is invoked for HS
files? If so, then -x assembler-with-cpp is already used for HS
files anyway.

What i'm hearing you say is we actually need TWO sets

flags, one
for normal haskell, and another for the CPP used on the

wheres this hardcoding?
DriverPipeline.hs -- grep for "assembler-with-cpp" and you
will find it.
IMHO best would be to move this "-x assembler-with-cpp"
into the
hs-cpp-flags managed by configure. This way it may be even
possible
to use system supplied plain cpp instead of cpp builtinto
GNU C.
