The special cases for GHC.Prim are a bit fragile.  We were relying on
(a) the base package to be already registered and (b) the base package
not to be hidden.  These used to be true with the old library build
system, but aren't true now.  I'm still not sure why we aren't seeing
failures at the moment, but this patch at least fixes the build with
'setup makefile'.

ifBuildable only runs a command it is given if the library in . either
must be built (core-package - readline) or is buildable.

When a snapshot version number is included, opt_HiVersion tends to exceed the range of a 32bit Int.

MERGE TO STABLE

ProjectTags is expected to be of the form -tag1-tag2 (i.e. the same as
Cabal tags). These are appended to the GHC version number.

A recent patch accidentally had x86_TARGET_ARCH instead of i386_TARGET_ARCH.

Initial support for loading x86_64 Mach-O files

In i386 position-independent symbol stubs, the NCG used to print
	jmp %edx
instead of
	jmp *%edx

Apple's assembler used to silently accept this, but has recently started to print warnings about it.

... so that GHCi doesn't complain about duplicate symbols when two C modules define the same static variable.

MERGE TO STABLE.

The __i686.get_pc_thunk symbols generated by gcc's PIC code generator are weak definitions that appear in every object file, so we need to deal with them.

and hopefully be a bit cleverer about finding things automatically.

This patch cleans up the GHC API, and adds some functionality: we can
now compile to object code inside GHCi.

Previously we had:

  data GhcMode
    = BatchCompile
    | Interactive
    | OneShot
    | JustTypecheck
    | MkDepend
  
  data HscTarget
    = HscC
    | HscAsm
    | HscJava
    | HscInterpreted
    | HscNothing

There was redundancy here; if GhcMode is Interactive, then only
HscInterpreted makes sense, and JustTypecheck required HscNothing.
Now we have:

  data GhcMode
    = CompManager       -- ^ --make, GHCi, etc.
    | OneShot           -- ^ ghc -c Foo.hs
    | MkDepend          -- ^ ghc -M, see Finder for why we need this

and HscTarget remains as before.

Previously GhcLink looked like this:

  data GhcLink = NoLink | StaticLink

Now we have:

  data GhcLink = NoLink | LinkBinary | LinkInMemory

The idea being that you can have an HscTarget of HscAsm (for example)
and still link in memory.

There are two new flags:

  -fobject-code selects object code as the target (selects
                either -fasm or -fvia-C, whichever is the default)
                This can be usd with ':set' in GHCi, or on the command line.

  -fbyte-code   sets byte-code as the target.  Only works in GHCi.
                One day maybe this could save the byte code in a file
                when used outside GHCi.

  (names chosen for consistency with -fno-code).

Changes to the GHC API: newSession no longer takes the GhcMode
argument.  The GhcMode defaults to CompManager, which is usually what
you want.  To do JustTypecheck now, just set hscTarget to HscNothing.

This use was the only thing keeping parsec in core-packages, and
we already have a dependency on alex+happy anyway.

3 small regexps were responsible for pulling 3 packages into core-packages.

The new code should also do a better job of hiding
"call-clobbered register used" warnings.

It used to be the case that
    autoreconf
in the root would also autoreconf in any libraries that need it, and
    ./configure
in the root would also configure all the libraries.

However, cabal now configures the libraries, so they were getting
configured twice.

Thus now a small shellscript, boot, autoreconfs the root and all libraries
that need it, and ./configure in the root doesn't configure the libraries.

* configure can be told where ld is
* make an hsc2hs-inplace.bat
* tell Setup configure about foo.bar rather than foo on Windows
* tell Setup configure to pass a --with-cc=$(CC) argument to ./configure

This patch updates the External Core creator, pretty-printer, and parser to
agree on a concrete syntax for External Core, including the constructs
required by the change to System FC. Code to create valid ASTs from External
Core files will come later, as will bits for renaming, typechecking, and
desugaring.

(we don't actually do anything useful either, because Cabal doesn't have
an install-docs option).

Some fixes to adjustor functions.  The 8-byte address returned by the 
allocator is adjusted to be aligned to 16-byte boundaries.  Fixed a typo 
in inserting an immediate address into an instruction.

This fixes the calls to 5-argument and 6-argument functions in ffi009.  
Some functions still break.  I suspect it's related to passing arguments on 
the stack.
