- The pns of X_regular and X_except are annotated in the opcode now.
- The memory input is annotated in the opcode now
- only nodes with X_regular, X_except are marked fragile

add unknown_jump opflag for the special case of a jump where we can't directly influence the destination and can't predict/change them

change backend node specification to use whole words instead of cryptical 1-char abreviations for flags

[r27277]

CSE neutral to its users, i.e. op(..., x, ...) ~ op(..., y, ...) if x and y are both neutral.
Setting this property to ia32_ProduceVal nodes allow to CSE nodes that differ in ProduceVals only (which themself NEVER are cse'd).
This "fixes" divmod.

[r26981]

  (with different arguments and register constraints for the same node now)
- Lots of cleanups/changes in the arm backend. We can represent all
  "shifter operands" now (but the code selection isn't optimal yet)
- More fixes all over the place - arm backend handles 164.gzip now

[r26673]

[r26648]

- Add a generic requirements+register+flag dumper to bearch; This avoids all
  backends/benode having their own slightly different dumpers
- Lots of cleanups in the backends along the way

[r26542]

	* benodes store the out register requirements in backend_info now
	  (this is work towards killing the register_requirement callbacks)
	* ir_graph has a pointer to beirg now
	* Other cleanups

[r26540]

  (We have a separate get_input, and get_output callback for now).
  This should make the code faster for now and is a first step towards
  changing the interface to query register constraints on the mode_T node
  itself instead of the Proj nodes.
- Handle middleend node constraints and stuff in benode.c instead of in each
  backend
- Remove irn_class_branch we already had is_cfop in the middleend
- Fix a bunch of bugs/problems in the process

[r26320]

Generate new_bd_* instead of new_rd_* functions in the backend.  The nodes are always created on the current irg.

[r23535]

	Node flags and node registers are stored in a generic backend_info struct now
	instead of every part of the backend doing custom (and slow) stuff

[r23142]

[r21303]

Rename arch_register_req_type_should_be_different to the more appropriate arch_register_req_type_must_be_different.

[r21302]

- add hash function for ia32 Immediates
- unified comments for all specifications
