Passing -C flag to GHC causes compiler panic:
{{{
addFlag by -C on the commandline: Warning:
The -fvia-C flag does nothing; it will be removed in a future GHC
release
ghc-stage2: panic! (the 'impossible' happened)
(GHC version 7.7.20130108 for x86_64-unknown-linux):
pipeLoop: at phase As but I wanted to stop at phase HCc
}}}
Comment in "main/DriverPipeline.hs", lines 665-668 suggests that this
behaviour might happen with native code generator. If C codegen is being
removed, then -C flag should perhaps be removed as well (also from the
documentation)?
