- SymConst's are now ALWAYS placed in the start block

Remove ProduceVal. Replace it by Xor0 (to produce 0), Sbb0 (to produce 0/-1) and by Keep to make Cltd register pressure faithful.

[r24128]

[r23600]

Handle replacement of ia32_Conv_I2I by Cwtl as peephole optimisation instead of handling it in the emitter.

[r23582]

Make the out edge verifier happy, when removing unnecessary ia32_Test, by not creating a result Proj, when there are no other users.

[r23555]

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

[r23535]

[r23474]

	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]

Fixed bug in conv-conv optimization: We have to assure, that we don't change the mode when deleting the conv.

Remove the unused parameter const arch_env_t *env from arch_irn_get_flags(), arch_irn_is() and arch_irn_consider_in_reg_alloc().

peephole_ia32_Test() would due to a bug only remove an ia32_Test if its direct successor was the desired node.  If the desired node was an indirect successor, it would incorrectly identify it as flags destroyer.

Partially undo r20786:  Emit ret $0 especially when its BB is only reached by a fallthrough, because this means its predecessor ends with a conditional jump.  According to the AMD Optimization guides, conditional jump directly followed by ret should be avoided.

[r21632]

Remove unnecessary condition in Load-to-Pop-optimisation: The Load does not need to have a Spill as memory predecessor. Especially the existing condition tests for Phis, which does not guarantee that there is a Spill.

[r21461]

[r21460]

[r21344]

[r21183]

Defer decision whether to create Test(x, x) instead of Cmp(x, 0) until peephole optimisation. This improves the code when Cmp(AM, 0) is undone by the flags repair phase.

[r21134]

[r21068]

[r20885]

[r20819]

Replace be_peephole_before_exchange()+sched_remove()+exchange()+be_peephole_new_node() by the new function be_peephole_exchange().

[r20788]

- only emit ret $0 on athlon if block has a label (= there is at least 1 jump
  to the block)
