ghc-stage2 binary name confusing for users
ghc-6.12.0.20091010 create a binary called $libdir/ghc-6.12.0.20091010/ghc-stage2 and then causing the program name ghc-stage2 to appear in compiler output and help etc which is confusing for users and a regression compared to 6.10.x IMHO.
eg
$ ghc
ghc-stage2: no input files
Usage: For basic information, try the `--help' option.
$ ghc --help
Usage:
ghc-stage2 [command-line-options-and-input-files]
To compile and link a complete Haskell program, run the compiler like
so:
ghc-stage2 --make Main
:
Alternatively, ghc-stage2 can be used to compile files individually. Each
input file is guided through (some of the) possible phases of a
compilation:
:
Given the above, here are some TYPICAL invocations of ghc-stage2:
# compile a Haskell module to a .o file, optimising:
% ghc-stage2 -c -O Foo.hs
# link three .o files into an executable called "test":
% ghc-stage2 -o test Foo.o Bar.o Baz.o
# compile a Haskell module to C (a .hc file), using a bigger heap:
% ghc-stage2 -C -H16m Foo.hs
# compile Haskell-produced C (.hc) to assembly language:
% ghc-stage2 -S Foo.hc
etc
I think either the output text should be changed or ghc-stage2 renamed to ghc.
