toInt wibble

Added expected stdout to reg. test for Float&Double exceptional IEEE values.
(the numbers were produced on a PII & with the MS C run-time -- don't be
surprised if you see slightly different numbers on your box.)

checking Main.main's type + newtype def that caused a ghc-X (X<4.03, I think) TC crash

Added Tree example from (older) versions of the Report

Extended to show why changing the defn of ReadS (and read) is a good idea

newtypes with a labelled field caused DS trouble sometime back

Bunch of H98 tests I had lying about

Don't insist that {-# OPTIONS ... #-} pragma is followed by \n

Doc'ed the (retirement?) home of fromInt and toInt

Handle -syslib com for non-installed builds ; dLL_ifs.hi is not a normal .hi file

mkVanillaModule: sigh, special treatment for module Main.

minor readIface tidyup

Since 'gcc -E' is the CPP we're now using, make good use of its
support for directly generating dependencies.

Cleanup of non-blocking I/O

- file descriptors are now always set to non-blocking mode.

- we don't do an inputReady operation on descriptors before
  attempting to read from them any more.

- the non-blocking flag on Handles has gone.

- the {set,clear}[Conn]NonBlockingFlag() functions have gone.

- the socket operations have been made to work properly with threads:
  accept is now non-blocking (it does a threadWaitRead instead of
  blocking), and the file descriptors returned by accept are set to
  non-blocking mode.

Win32 will need some adjustments, no doubt.

Fix for DEBUG && !PROFILING

mingw32 support

NumExts.showListWith doc'ed

Main trunk is now 4.05.

Minor Win32 changes

Magic Constant Removal

Minor tweaks to do with DLL building

Disable timer ticks on 'pure' Win32 platforms unless really needed
(for profiling) -- no reason to enable it elsewhere as the Win32 bits
doesn't currently support thread{Delay,Wait{Read,Write}}#

Move DllMain() into separate file + it doesn't call startupHaskell()
any longer upon loading of the DLL. That is the task of clients of
the RTS.

Add cmp_thread

Code that trundles over stable_ptr_table need to start at index 1,
as index 0 is unused (and may contain garbage.)

When constructing vanilla modules from ModuleNames, consult the HiMaps
to make sure we're using the 'right' kind of Module (i.e., it has got
the DLL flag correctly set.)

mkVanillaModule: made DLL savvy

Cost-centre heap profiling and symbol table heap profiling are now
merged into one file: ProfHeap.c.

Heap Profiling
--------------

This commit adds simple hp2ps-style heap profiling.  Just the '-h'
option is supported so far.

Heap profiles will show the top two cost centres on each cost centre
stack.

Time/Alloc profiles have been extended to aggregate the costs on a
per-cost-centre basis and show the table of highest consuming cost
centres before the full table of cost centre stacks.

Profiles work best if '-caf-all' is used, especially when using
one of the '-auto' flags.

Extra words about unsafePerformIO

A couple of fixes and cleanups to ticky-ticky profiling:

	- remove UPD_EXISTING (doesn't make sense)
	- add UPD_CON_IN_PLACE, now that we have in-place updates
	- clean up the output a little.

gcc 2.95 on Sparc changed the assembly output slightly.  This should
fix it.

GHC's web pages have moved to http://www.haskell.org/ghc/.

updated

Only use initUserSignals() if you've got it defined

GMP only depends on libiberty for the implementation of random().
Avoid this dep. on a (pure) Win32 platform.

Win32 version of awaitEvent(). Easy :)

oops, back out last change.  It was already there.

Fix building with profiling.

In case of a partial writes, buffer pointer wasn't being adjusted/used.
