The phase at which to STOP processing is determined by a command-line
option:
+ -E stop after generating preprocessed, de-litted Haskell (used in conjunction with -cpp)
-C stop after generating C (.hc output)
- -E stop after generating preprocessed C (.i output)
-S stop after generating assembler (.s output)
-c stop after generating object files (.o output)
-M Output the Makefile rules recording the
dependencies of a list of Haskell files.
- (ghc driver just calls upon the help of a
- compatible mkdependHS script to do the
- actual processing)
+ (ghc driver script calls upon the help of a
