Print
   "Interface file unchanged"
and
   "Module version unchanged, but usages differ; hence need new hi file"
only when -ddump-rn-trace flag has been given. This is more consistent
with the rest of GHC and the *nix world, and messes up less tests.

Added semicolon to synch with current interface file syntax.
Note: The `class' line contains a kind bug, but this is not
checked. Bug or feature?

Removed foralls in expected output

Synched expected output with reality

Litlits don't really make much sense for the NCG (i.e. are a hack), so
compile via C.

Reverted my last change to this file: Constant folding should really
yield *excatly* the same result as runtime computation.

Synched with reality again. The expected output is a extremely fragile...

Putting parentheses around expressions involving a mixture of
multiplicative and additive operators might sometimes be a cunning
idea...   :-}   Otherwise
   (591125662431::Int) `div` (517::Int)
is correctly converted into
   (567659506 + (275 * 2147483647)) `div`  517
but
    591125662431       `div` (517::Int)
turns into the messed up
    567659506 + ((275 * 2147483647) `div`  517)

Add note that `gmake clean' should *not* destroy the work of `gmake boot'.
In all cases, the sequence autoconf, ./configure, gmake boot, gmake clean,
gmake all should work correctly.

** Please verify that this is indeed the case! **

DEBUG ==> NCG_DEBUG

D'oh!  Only generate split markers when actually splitting

DEBUG ==> NCG_DEBUG

fix phase ordering for NCG + -split-objs.

Insert split markers properly in the NCG.  -split-objs is on its way
to working with the NCG.

dead code removal

Removed -noC flag, which has vanished from the driver

Don't use addr2Integer for large integral literals anymore, use a
Horner schema with numbers in the Int range instead. This improves
constant folding, so e.g.  (0x87654321 :: Word32) is evaluated at
compile time now. In theory we can completely say Good-bye to
addr2Integer, but for the time being it's still there. Feel free to
nuke it...  >:-)

Don't warn the user about integer overflow during constant folding
anymore. It's not done at runtime either, and compilation of
completely harmless things like

   ((124076834 :: Word32) + (2147483647 :: Word32))

yielded a warning.

Hackily quote -#include options before passing them to mkdependHS

Remove parentheses around C function/macros names. This is necessary
because cpp does *not* replace e.g.

   (eqForeignObj)(f1,f2)

with

  ((f1)==(f2))

(see PrimOps.h), heaven (or K&R) knows why. OK foreign importing
macros is a hack, but GHC seems to depend on it.

- fix copyrights
- remove some unused imports
- comment formatting fixes

In a CCall, a DynamicTarget has a unique that is
used only to generate a uniquely-named typedef.
It should not be used when comparing CCalls (e.g.
when seeing if interface files have changed).
So the main change in this commit is to fix the Eq
instance for PrimOp.CCallTarget, but I took the
opportunity to clean up the CCallTarget interface
a little.

Improve error message

wibble

Use GhcMinVersion to pick the correct cmdline args to build the driver.

Check the version of the installed ghc, and set GhcVersion,
GhcMajVersion, GhcMinVersion and GhcPatchLevel make variables.

_Haskell1Version ==> cHaskell1Version

Added test for Typeable instance

Fixed buglet in search for ghc-usage.txt

There is not much point in memoising Integers, so we should better use
unary "numbers" (i.e. lists of units) instead

Add my wizardly assembly-code basic-block matching program, which is
very useful for debugging the native code generator.  This is not
built by default, because it's totally useless to anyone except the
GHC developers.  The README file describes how to use and maintain it.

Add missing implicit occs relating to list comprehensions in
deriving (Ix,Read).

Add test for GNU regex in libc, which we'll use to decide whether to
compile our own copy of the library in package text.

sparc needs the TMOVEDIRVS hack too

hi files are now named after the module being compiled, not the
original filename (unless of course the user has specified -ohi <blah>).

Remove /bin/ from /bin/rm to avoid problems with systems where it's elsewhere.

Make it so that implicit params uniformly print with the `?' at the front
of the name.  Simon's last big commit re-arranged how interface files
were written, and implicit params were suddenly being written without the `?'.
This fixes both that bug, and Simon's concern that there were too many
different pretty printing functions for implicit params ;-)

This file had version 407 burned into it; the convention is that zero
means "don't check the version".

Bumped VERSION's version as well.
