Good day and welcome to the FIRM XMALLOC*() macros.  These macros are provided for the type safety and convenience of the IPD research facility personnel.  The time is 15:32.  Check xmalloc.h for details.

- Started working on flags

[r12716]

- more work on state registers for x87 fpu rounding modes

- Replace limit callback in register requirements with a simple bitset
- Fix backends, generators and the rest of the code for the change register
  requirements structure
- Eliminated the custom register_requirement structures in the backend, they
  are pointless now, use the normal arch_register_req_t
- Fix TEMPLATE backend
- Extract emitter framework from ia32 and provide generic header/code for it
- Port TEMPLATE backend to new emitter
- Extract gas specific emit stuff (declarations, sections) from ia32 backend
  and provide it as generic header/code. Make TEMPLATE backend use that
- Remove several FIRM_DBG_REGISTERs from functions which are called very often.
  Before we had millions of string hashtable lookups because of that. The
  prefered way is to have 1 static debug module per file and initialize it in
  the module constructor. No passing around in environment structs and in no
  case should you dynamically register it in single functions.

- Fixes for compilation without DEBUG_libfirm
- Fixed for compilation without WITH_LIBCORE (but it's still broken)

- refactored backend to store some analysis info about the irg in the be_irg structure, added assure_ and invalidate_ functions for this

 - skip_from_uses simply crashed ...

  walking occurs before finish phase now
- changed ia32 to do some things transforms from finish phase in after_ra phase
  already but do peephole optimization in finish phase.
- Added a peephole optimisation that transform IncSP,Store cascades to
  Pushs
- Replaced several HASH_PTR with nodeset_hash to make compiler more
  deterministic.

Added becopyheur3 (need to compile firm with --enable-jvm)

- Morgan now calls be_spill_phi when spilling phi nodes
- no need to use beinsn in morgan analysis phase, simple iterating over in_edges is enough
- fixed bug in morgan spiller that marked some values as livethrough unused which were not

blocks or loops). Other small changes:

* Added some verify functions that check for register pressure or valid schedules (replaces the broken check_pressure in bechordal_main.c)
* Some style/readability improvements to the belady spill code
* Some style/readability improvements to beuses.*
* Fixed registerpressure stat dumper
* Some improvements to bespill.c: When spilling already reloaded values, don't add a 2nd spill.
