4 This is the driver script for the Glasgow Haskell compilation system.
5 It is written in \tr{perl}. The first section includes a long
6 ``usage'' message that describes how the driver is supposed to work.

20 Use of the Glorious Haskell Compilation System driver:
22 $Pgm [command-line-options-and-input-files]
24 ------------------------------------------------------------------------
25 This driver ($Pgm) guides each input file through (some of the)
26 possible phases of a compilation:
28 - unlit: extract code from a "literate program"
29 - hscpp: run code through the C pre-processor (if -cpp flag given)
30 - hsc: run the Haskell compiler proper
31 - gcc: run the C compiler (if compiling via C)
32 - as: run the assembler
35 For each input file, the phase to START with is determined by the
37 - .lhs literate Haskell: unlit
38 - .hs illiterate Haskell: hsc
39 - .hc C from the Haskell compiler: gcc
40 - .c C not from the Haskell compiler: gcc
41 - .s assembly language: as
42 - other passed directly to the linker: ld
44 If no files are given on the command line, input is taken from
45 standard input, and processing is as for an .hs file. (All output is
46 to stdout or stderr, however).
48 The phase at which to STOP processing is determined by a command-line
50 -E stop after generating preprocessed, de-litted Haskell (used in conjunction with -cpp)
51 -C stop after generating C (.hc output)
52 -S stop after generating assembler (.s output)
53 -c stop after generating object files (.o output)
55 Other commonly-used options are:
57 -O An `optimising' package of compiler flags, for faster code
59 -prof Compile for cost-centre profiling
60 (add -auto for automagic cost-centres on top-level functions)
62 -fglasgow-exts Allow Glasgow extensions (unboxed types, etc.)
64 -H14m Increase compiler's heap size
66 -M Output the Makefile rules recording the
67 dependencies of a list of Haskell files.
68 (ghc driver script calls upon the help of a
69 compatible mkdependHS script to do the actual
72 The User's Guide has more information about GHC's *many* options.
74 Given the above, here are some TYPICAL invocations of $Pgm:
76 # compile a Haskell module to a .o file, optimising:
78 # link three .o files into an executable called "test":
79 % $Pgm -o test Foo.o Bar.o Baz.o
80 # compile a Haskell module to C (a .hc file), using a bigger heap:
81 % $Pgm -C -H16m Foo.hs
82 # compile Haskell-produced C (.hc) to assembly language:

660 GHC allows very precise control of what happens during a compilation.
661 Core-to-Core and STG-to-STG passes can be run in any order, as many
662 times as you like. Individual transformations can be turned on or
665 Sadly, however, there are some interdependencies \& Things You Must
666 Not Do. Here is the list.
670 \item[\tr{-fspecialise}:]
671 The specialiser must have dependency-analysed input; but if you run
672 the simplifier to do this, you must not let it toss away unused
673 bindings! (The typechecker conveys some specialisation info via
674 ``unused'' bindings...)
676 \item[\tr{-ffloat-inwards}:]
677 Floating inwards should be done before strictness analysis, because
678 the latter will give better results.
680 \item[\tr{-fstatic-args}:]
681 The static-arguments-transformation pass {\em must} have the
682 simplifier run right after it.
684 \item[\tr{-fcalc-inlinings[12]}:]
685 Not required, but there may be slight gains by re-simplifying after
686 this is done. (You could then \tr{-fcalc-inlinings} again, just for
689 \item[\tr{-ffull-laziness}:]
690 The (outwards-)let-floater should be the {\em last} Core-to-Core pass
691 that's run. (Um, well, howzabout the simplifier just once more...)
