Add things I discovered on my last performance sweep (this was several
weeks ago).

new program

catchAllIO -> catch

Stop using ANNA_DIR environment variable, which for various sad reasons
doesn't work on Windows.

Add an (Ord a) context on an Ix instance which is required now.

Add two digits-of-e programs

-syslib lang unnecessary

Tart up comments

More bogus results

Update output because of changed defaulting rules

basic mingw headers doesn't define M_PI; make fft.c cope

Another out variant (FP wibbles).

Another output variant (FP wibbles).

Yet another output variant.

Add yet another output variant.  One could be forgiven for suspecting that
this program is not numerically stable, and gives not just differing coords
but also different numbers of points as a result.

Cleanup in parallel section of nofib suite. The fibish fcts are ok, i.e.
std way should succeed, parallel way should build.
Parallel way has to be run by hand (problems redirecting stdout), so not
automatic check whether output is identical to the provided file.
Added a bunch of test prgs for GdH in distributed section. Still need
to be integrated into nofib build machinery (currently standalone Makefiles).
Modified Makefiles to work with a parallel build. Have to omit runtest for now.

put back hartel subdir that hwl removed.

This commit covers changes in GHC to get GUM (way=mp) and GUM/GdH (way=md)
working. It is a merge of my working version of GUM, based on GHC 4.06,
with GHC 4.11. Almost all changes are in the RTS (see below).

GUM is reasonably stable, we used the 4.06 version in large-ish programs for
recent papers. Couple of things I want to change, but nothing urgent.
GUM/GdH has just been merged and needs more testing. Hope to do that in the
next weeks. It works in our working build but needs tweaking to run.
GranSim doesn't work yet (*sigh*). Most of the code should be in, but needs
more debugging.

ToDo: I still want to make the following minor modifications before the release
- Better wrapper skript for parallel execution [ghc/compiler/main]
- Update parallel docu: started on it but it's minimal [ghc/docs/users_guide]
- Clean up [nofib/parallel]: it's a real mess right now (*sigh*)
- Update visualisation tools (minor things only IIRC) [ghc/utils/parallel]
- Add a Klingon-English glossary

* RTS:

Almost all changes are restricted to ghc/rts/parallel and should not
interfere with the rest. I only comment on changes outside the parallel
dir:

- Several changes in Schedule.c (scheduling loop; createThreads etc);
  should only affect parallel code
- Added ghc/rts/hooks/ShutdownEachPEHook.c
- ghc/rts/Linker.[ch]: GUM doesn't know about Stable Names (ifdefs)!!
- StgMiscClosures.h: END_TSO_QUEUE etc now defined here (from StgMiscClosures.hc)
                     END_ECAF_LIST was missing a leading stg_
- SchedAPI.h: taskStart now defined in here; it's only a wrapper around
              scheduleThread now, but might use some init, shutdown later
- RtsAPI.h: I have nuked the def of rts_evalNothing

* Compiler:

- ghc/compiler/main/DriverState.hs
  added PVM-ish flags to the parallel way
  added new ways for parallel ticky profiling and distributed exec

- ghc/compiler/main/DriverPipeline.hs
  added a fct run_phase_MoveBinary which is called with way=mp after linking;
  it moves the bin file into a PVM dir and produces a wrapper script for
  parallel execution
  maybe cleaner to add a MoveBinary phase in DriverPhases.hs but this way
  it's less intrusive and MoveBinary makes probably only sense for mp anyway

* Nofib:

- nofib/spectral/Makefile, nofib/real/Makefile, ghc/tests/programs/Makefile:
  modified to skip some tests if HWL_NOFIB_HACK is set; only tmp to record
  which test prgs cause problems in my working build right now

remove import of fromInt

add -package lang

Fix imports.

import GlaExts is now out-of-date.

Add -package lang.

add "integer"

Add a reasonable Int vs. Integer benchmark.

Don't pass -K in SRC_HC_OPTS, as it is no longer supported.

fix $(TOP)

sparc result

sparc results

sparc results

Add a result for sparc-solaris (the usual FP rounding errors).

Track recent library changes.

Yet another candidate for the Correct Output of this test.

Merge Windows fixes and tidying from ghc-4-07-branch

Merge fixes from ghc-4-07-branch

Remove spurious white space (esp. potentially make-confusing tabs).

Add notes on nofib programs

Removed carriage returns (\r) from source files. Please don't check in such
things; they can cause problems on Cygwin (funnily enough). I'm looking into
how to avoid commiting carriage returns when working under Windows.

Add cacheprof.

-fglasgow-exts is not needed for cacheprof.
