[Stop using mremap() to allocate space for trampolines
Simon Marlow <marlowsd@gmail.com>**20080915145924
 
 This was causing problems because sometimes mremap() moved the memory
 we had allocated from the low 2Gb to above the 2Gb boundary, causing
 some linkages to fail.  There's no MAP_32BIT flag to mremap().
 
 So now we just use mmap(MAP_ANON|MAP_32BIT) to allocated space for the
 trampolines.  People without MAP_32BIT (eg. *BSD) will still have to
 do something else here, such as allocating memory from a fixed
 address; so I've made it slightly easier for those guys, but there's
 still work to do (#2063).
 
 One solution (that Simon PJ is advocating) is to turn on -fPIC by
 default on x86-64.  This is a good solution as it removes the need for
 MAP_32BIT, but doesn't work with -fvia-C, so probably this is for
 later.

 This is just a tidy-up.  Previously we were calling occurAnalyse
 twice on each LHS which was silly and a bit unclean too.  
 
 This patch should have no overall effect, though.

[Do not use the Static Arg Transformation by default with -O2
simonpj@microsoft.com**20080915150433
 
 Max has some more heuristics to add, and is meanwhile worried
 that having SAT on by default will make some highly-tuned array
 programs worse.  So it's off by default.  
 
 Use -fstatic-argument-transformation to switch it on.

[Use 'GhcMonad' in GHC and split up checkModule into phases.
Thomas Schilling <nominolo@googlemail.com>**20080914232044
 
 I'm not sure I covered all the ways of throwing errors in the code.
 Some functions throw ProgramErrors, some error messages.  It's still
 quite a mess, but we're getting closer.  The missing cases are mostly
 errors that cannot be fixed by the API client either or are a result
 of wrong usage, so are in any case fatal.
 
 One function, 'getModuleInfo', still returns a 'Maybe', but the
 documentation suggests it should always succeed.  So I may change that
 soon.
 
 The spit-up of of 'checkModule' has pros and cons.  The various forms
 of 'checkModule*' now become:
 
  checkAndLoadModule ms False ~~>
     loadModule =<< typecheckModule =<< parseModule (ms_mod_name ms)
 
  checkAndLoadModule ms True ~~>
    loadModule =<< desugarModule =<< typecheckModule =<< parseModule (ms_mod_name ms)
 
  checkModule mn False ~~>
    typecheckModule =<< parseModule mn
 
  checkModule mn True ~~>
    desugarModule =<< typecheckModule =<< parseModule mn
 
 The old APIs cannot easily be provided, since the result type would be
 different depending on the second argument.  However, a more
 convenient API can be modelled on top of these four functions
 ({parse,typecheck,desugar,load}Module).

[Introduce an 'ExceptionMonad' class.
Thomas Schilling <nominolo@googlemail.com>**20080914172154
 
 This monad provides variants of 'catch', 'bracket', and 'finally', so
 exceptions can be handled in monads that wrap IO.  The latter two
 methods need to be part of the class definition, because GHC uses
 'block' and 'unblock' which are used in the definition of those two
 methods for the IO monad.  A perhaps better class interface would
 consist of 'gcatch', 'gblock', and 'gunblock' and let the latter two
 default to 'id' like is done for non-GHC implementations of 'bracket'
 and 'finally'.
