Remove duplicate definition of unblockOne.

Reset the interrupted flag after an interruption.  This allows
finalizers to run, and means that Hugs doesn't get stuck in an
interruption loop.

Saturday Night Fever: hPutBufBA again... >:-(

Removing backend.h for Julian.

Update .c files to reflect reorganisation of .h files in this directory.

Major cleanup of header files.  Merge the 5 deleted files into connect.h.
Organise connect.h to gather declarations into roughtly related
categories.

Nuke a substantial number of no-longer-supported options.

First stab at reviving TREX - just fixing some header wibbles.  Also one small
fix to get implicit parameters working (`textOf' needed to be taught that
IPCELLs are also OK).  Moved #defines for TREX, IPARAM, etc, into options.h
(in their previous location at the end of prelude.h, they were being defined
too late).

Fix h{Fill,Put}Buf(BA)?.  They now work in the presence of
partial/blocking reads and writes, and hPutBuf now doesn't hold on to
the handle while it's blocking.

Fix h{Fill,Put}Buf(BA)?.  They now work in the presence of
partial/blocking reads and writes, and hPutBuf now doesn't hold on to
the handle while it's blocking.

Compilation cleanups:
* Add some prototypes to header files, to avoid compilation warnings.
* Remove irrelevant #ifdeffery (#if NPLUSK, + various others)

Rm debugging printf.

Wibble: rm needless import Prelude used by Hugs.

Added some NOINLINE pragmas for unsafePerformIO/newIORef hacks.

Correct bug in local fixity decls (reported by Michael Hudson)

Changed an #ifdef so that the Prelude can be builit again by GHC.

Add fixity tests

Removed a typo, i.e. ]\begin{code} => \begin{code}

Disable module initialisation under Hugs until we can sort out the
hairy linking issues.

Porting bug fix from Classic Hugs to STG Hugs. This was
causing crashes when compiling large examples.

Removing some dead code from static.c

- remove hack which treats '_[A-Z]+' as a constructor token.  This
  isn't required now that everything in interface files is Z-encoded.

syslib data depends on syslib lang.

improving the synatax and semantics of the privileged import

 Typical use might be:

  import Prelude
  import privileged Prelude ( IORef , unsafePerformIO )

 Which means please ignore the export that comes with Prelude,
 and let me at compiler internal magic operations, IORef and
 unsafePerformIO (both are later exported by IOExt)

I've also updated the stdlib files to use this (hugs only :-).

Changing use literate programming, to allow hugs to compile this program.

Changing name of linkPreludeNames to linkPrimitiveNames (cause that
is what it does).

Adding a Hugs extension "import privileged". This will allow us
to remove the many exports from the prelude of the primitive functions
and types, but still allow us to write libraries that use it.

A Prelude where IO is an abstract type, not a synonm.

Previously, IO type errors were getting explained in terms of ST RealWorld.

Adding version of Makefile that looks in the new location for Prelude.hs

Adding the latest version of the makefile
Removing Prelude.hs from the lib dir

Moved Prelude.hs for STG Hugs to ghc/lib/hugs/Prelude.hs

This means that everything in the ghc/interpreter/lib directory
is generated. The new makefile for interpreter/lib will be added
shortly.

- generalise the per-module initialisation stubs so that we use it
  in normal (non-profiled) code too.  The initialisation stubs are
  now called '__init_<module>' rather than '_reg<module>'.

- Register foreign exported functions as stable pointers in the
  initialisation code for the module.  This fixes the foreign export
  problems reported by several people.

- remove the concept of "module groups" from the profiling subsystem.

- change the profiling semantics slightly; it should be unnecessary
  to use '-caf-all' to get reasonable profiles now.

okToUnfoldInHiFile: look at args of a Con for litlits.

Define EXTERN_SYMS_linux for Linux.

Attempt to fix the Sparc version of StgRun.  Since
RESERVED_STACK_SPACE increased beyond the size of a 13-bit immediate,
the Sparc code has been broken.

We try to fix this with some imaginative gcc inline assembly
constraints.  If this breaks again, I'll try recoding it directly in
assembler.

While I'm here, pull in some of the comments from the old pre-4.00 RTS
and add some new comments.

Complete the initial implementation and debugging of the Win32 PE
(PEi386) linker.

oops, need to define prof_file when DEBUGging too.

Don't GC after a stack overflow.  This might have been necessary
temporarily, but isn't any more.

Remove duplicate prof_file variable.  Heap profiling should work again.

Move the x86 startup code into StgCRun.c, and remove StgRun.S.
Although the assembly version was much cleaner, it didn't extend the
stack properly in the case when the host architecture requires it to
be extended a page at a time (eg. Win32).  We now rely on the C
compiler to do this properly.

Properly fix a sprintf bug in typeInstDefn().

Fixing a sprintf bug; it was clobering the symbol table.
If you used a name for a class and module, the module
was not recognised as read.
