>GHC without ––make
Without ––make, GHC will compile one or more source files given on the command line.
The first phase to run is determined by each input-file suffix, and the last phase is determined by a flag. If no relevant flag is present, then go all the way through linking. This table summarises:
|Phase of the compilation system||Suffix saying “start here”||Flag saying “stop after”||(suffix of) output file|
|C pre-processor (opt.)||.hs (with -cpp)||-E||.hspp|
|Haskell compiler||.hs||-C, -S||.hc, .s|
|C compiler (opt.)||.hc or .c||-S||.s|
Thus, a common invocation would be: ghc -c Foo.hs
Note: What the Haskell compiler proper produces depends on whether a native-code generator is used (producing assembly language) or not (producing C). See Section 4.12.6 for more details.
Note: C pre-processing is optional, the -ccpflag turns it on. See Section 4.12.3 for more details.
Note: The option -E runs just the pre-processing passes of the compiler, dumping the result in a file. Note that this differs from the previous behaviour of dumping the file to standard output.
