This is the driver script for the Glasgow Haskell compilation system.
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)
-H14m Increase compiler's heap size
+ -M Output the Makefile rules recording the
+ dependencies of a list of Haskell files.
+ (ghc driver script calls upon the help of a
+ compatible mkdependHS script to do the actual
+ processing)
+
The User's Guide has more information about GHC's *many* options.
Given the above, here are some TYPICAL invocations of $Pgm:
# compile a Haskell module to a .o file, optimising:
% $Pgm -c -O Foo.hs
+ # link three .o files into an executable called "test":
+ % $Pgm -o test Foo.o Bar.o Baz.o
# compile a Haskell module to C (a .hc file), using a bigger heap:
% $Pgm -C -H16m Foo.hs
# compile Haskell-produced C (.hc) to assembly language:
% $Pgm -S Foo.hc
- # link three .o files into an executable called "test":
- % $Pgm -o test Foo.o Bar.o Baz.o
