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

14 \section[Driver-usage]{Usage message}

22 Use of the Glorious Haskell Compilation System driver:
24 $Pgm [command-line-options-and-input-files]
26 ------------------------------------------------------------------------
27 This driver ($Pgm) guides each input file through (some of the)
28 possible phases of a compilation:
30 - unlit: extract code from a "literate program"
31 - hscpp: run code through the C pre-processor (if -cpp flag given)
32 - hsc: run the Haskell compiler proper
33 - gcc: run the C compiler (if compiling via C)
34 - as: run the Unix assembler
35 - ld: run the Unix linker
37 For each input file, the phase to START with is determined by the
39 - .lhs literate Haskell: lit2pgm
40 - .hs illiterate Haskell: hsp
41 - .hc C from the Haskell compiler: gcc
42 - .c C not from the Haskell compiler: gcc
43 - .s assembly language: as
44 - other passed directly to the linker: ld
46 If no files are given on the command line, input is taken from
47 standard input, and processing is as for an .hs file. (All output is
48 to stdout or stderr, however).
50 The phase at which to STOP processing is determined by a command-line
52 -C stop after generating C (.hc output)
53 -E stop after generating preprocessed C (.i output)
54 -S stop after generating assembler (.s output)
55 -c stop after generating object files (.o output)
57 Other commonly-used options are:
59 -O An `optimising' package of options, to produce faster code
61 -prof Compile for cost-centre profiling
62 (add -auto for automagic cost-centres on top-level functions)
64 -fglasgow-exts Allow Glasgow extensions (unboxed types, etc.)
66 -H14m Increase compiler's heap size
68 The User's Guide has more information about GHC's *many* options.
70 Given the above, here are some TYPICAL invocations of $Pgm:
72 # compile a Haskell module to a .o file, optimising:
74 # compile a Haskell module to C (a .hc file), using a bigger heap:
75 % $Pgm -C -H16m Foo.hs
76 # compile Haskell-produced C (.hc) to assembly language:
78 # link three .o files into an executable called "test":
79 % $Pgm -o test Foo.o Bar.o Baz.o

1318 We come now to the default ``wads of options'' that are turned on by
1319 \tr{-O0} (do min optimisation), \tr{-O} (ordinary optimisation),
1320 \tr{-O2} (aggressive optimisation), or no O-ish flag (compile speed is
1323 The user can also specify his/her own list of options in a file; in
1324 that case, the work is already done (see stuff about @minusO3@,
1327 GHC allows very precise control of what happens during a compilation.
1328 Core-to-Core and STG-to-STG passes can be run in any order, as many
1329 times as you like. Individual transformations can be turned on or
1332 Sadly, however, there are some interdependencies \& Things You Must
1333 Not Do. Here is the list.
1335 CORE-TO-CORE PASSES:
1337 \item[\tr{-fspecialise}:]
1338 The specialiser must have dependency-analysed input; but if you run
1339 the simplifier to do this, you must not let it toss away unused
1340 bindings! (The typechecker conveys some specialisation info via
1341 ``unused'' bindings...)
1343 \item[\tr{-ffloat-inwards}:]
1344 Floating inwards should be done before strictness analysis, because
1345 the latter will give better results.
1347 \item[\tr{-fstatic-args}:]
1348 The static-arguments-transformation pass {\em must} have the
1349 simplifier run right after it.
1351 \item[\tr{-fcalc-inlinings[12]}:]
1352 Not required, but there may be slight gains by re-simplifying after
1353 this is done. (You could then \tr{-fcalc-inlinings} again, just for
1356 \item[\tr{-ffull-laziness}:]
1357 The (outwards-)let-floater should be the {\em last} Core-to-Core pass
1358 that's run. (Um, well, howzabout the simplifier just once more...)
1363 \item[\tr{-fupdate-analysis}:]
1364 It really really wants to be the last STG-to-STG pass that is run.
