More {-# OPTIONS .. #-} tweaks: handle -#include "..." (where
'handle' == 'ignore'.)

Make platform-specific dynamic loaders add ".so", ".dll" etc to
library names, so that f-i decls can be written without them.
Modify Prelude accordingly.

Remove unused functionality in dynamic.c and make err msgs a bit
better.

Don't warn user of unrecognised options when processing
{-# OPTIONS .. #-} pragmas.

More RULES documentation

Use C-style comments instead of assembler comments - the '#' confuses
cpp when mkdependC'ing.

Support for "{-# OPTIONS <opts> #-}" in headers of (de-litted)
source files. Currently, only -syslib <foo> and "-fglasgow-exts"
settings are picked up from within <opts>.

Mildly tested; give it a twirl.

remove debug printing -- wibble

Dot-ify local labels.

universal_call_c_x86_stdcall: assume *I* have been ccall'd, not
stdcall'd, so don't clear my own args on return.

reduce block size to 4k

small cleanup; reduce amount of conditionally-compiled stuff

Add way 's', for SMP/PThreads

Junk removal

Fix crashes in re_search.  Several other functions in this file need
fixing too.

Add foreign import/export implementations for x86 stdcall convention.

Make parser notice calling conventions on f-i and f-x declarations,
check they are supported on the platform Hugs is compiled on.  Pass
them all the way through the code generator to the interpreter.

Allow f-i/f-x decls to omit the calling convention, in which case
ccall is used.  Remove calling convention from all such decls
in the Prelude so it will work on any platform.

markStablePtrTable: correctly handle case when one stable ptr refers
to an indirection to an item referred to directly by a second
stable ptr (I think!).

wibble

Foreign imports that use ByteArrays now need to be marked as being 'unsafe.'

Fix documentation installing in a binary dist.

FFI wibble:

* disallow the use of {Mutable}ByteArrays in 'safe' foreign imports.
* ensure that ForeignObjs live across a _ccall_GC_.

Adding a axiomatic testing framework library to help test Hugs and GHC
libraries.

Here is the example for the test of concat.

test_concat = testRules "concat" [
	do (xss :: [[ALPHA]]) <- var "xss"
	   concat xss <==> foldr (++) [] xss
	]

xss here ranges over various rendering of list of list,
including bottom and lists containing bottom.

<==> uses a small piece of compiler/interpreter specifics to
allow testing for

	error "" ... <==> ... error "" ===> Pass

* Completion of foreign import and foreign export for x86 ccall
  convention.  f-i's and f-x's can pass and return
  Char Int Word Addr StablePtr Float and Double.

* Significant cleanups and infrastructure improvements.
  Characterise functions by (instruction set, calling convention)
  pair where necessary, since that's what counts.

  Moved foreign export code into rts/ForeignCall.c.
  Should now be in a good position to implement x86 stdcall
  convention.

wibble

Cleanup of the foreign import code.  Also allow StablePtrs
to be passed back and forth.

made writeErrString__ f.i. unsafe

Dotted the i's

Add some missing ticky macros.

Eliminate those annoying "unexpected lazy BHing required" messages
during ticky-ticky profiling.

Micro-optimisation: don't need to test for an empty queue in a
BLACKHOLE_BQ, now that we're distinguishing BLACKHOLE and
BLACKHOLE_BQ.  Shortens the update code by a couple of instructions.

Back out prev. commit which POSIXified getClockTime() - non-POSIX calls
really are superior (better resolution.)

Adding final diffs between Hugs98 (Jan99) and Hugs98 (Sep99)
manually to STG Hugs.

Adding a generic version of universal call that
only works for specific argument patterns.

It allows ports to work on the Hugs Prelude immeduately,
even if univeral_call_c_<os/specific> is not ported.

Also, commented out (longstanding?) bug with incorrect call
to setCurrModule.

use PUSH_ON_RUN_QUEUE macro instead of (slightly less efficient)
inline version.

ASSERT that the tso link field is empty before pushing it on the end
of a queue.

Increase default cutoff limit from 16 to 60.  nofib/real/anna
won't compile even with this value set to 50.  Presumably the
same problem afflicts Hugs98-Sept98 ?

Remove debugging export of ST(..), which causes failures in nofib.

Wibble.

Make typeVarsIn non-static since interface.c needs to see it.

Change CFunDescriptor to match new foreign import implementation.

Reimplement back-end for foreign import (calling out).

Return to a cleaned-up version of Alastair's callfun.S,
wherein an architecture and calling-convention specific
piece of assembly code is used to construct arguments and
then call the specified function, under the direction of
a type descriptor string.

Defined an interface to this function (universal_call_c)
which I hope will work regardless of 32-or-64 bitness,
endianness and calling convention.

Current implementation is for x86-linux only.
