* move all the target's asmprinters into the main target. The piece Chris Lattner2010-11-1440-188/+16

* Teach InstructionSimplify about phi nodes. I chose to have it simplyDuncan Sands2010-11-142-2/+5
| | | | | | | | | | offload the work to hasConstantValue rather than do something more complicated (such handling mutually recursive phis) because (1) it is not clear it is worth it; and (2) if it is worth it, maybe such logic would be better placed in hasConstantValue. Adjust some GVN tests which are now cleaned up much further (eg: all phi nodes are removed). llvm-svn: 119043
* Boost the power of phi node constant folding slightly: if allDuncan Sands2010-11-141-12/+18
| | | | | | | | | | | operands are the phi node itself or undef, then return undef. This logic already existed at a higher level so in practice it shouldn't make the slightest difference. Note that this code could be replaced by a call to PN->hasConstantValue(). However since we bail out the moment we see a non-constant operand, it is more efficient to have a specialized version of that logic. llvm-svn: 119041

* Generalize the reassociation transform in SimplifyCommutative (now renamed toDuncan Sands2010-11-135-46/+128
| | | | | | | | | | | | | | | | SimplifyAssociativeOrCommutative) "(A op C1) op C2" -> "A op (C1 op C2)", which previously was only done if C1 and C2 were constants, to occur whenever "C1 op C2" simplifies (a la InstructionSimplify). Since the simplifying operand combination can no longer be assumed to be the right-hand terms, consider all of the possible permutations. When compiling "gcc as one big file", transform 2 (i.e. using right-hand operands) fires about 4000 times but it has to be said that most of the time the simplifying operands are both constants. Transforms 3, 4 and 5 each fired once. Transform 6, which is an existing transform that I didn't change, never fired. With this change, the testcase is now optimized perfectly with one run of instcombine (previously it required instcombine + reassociate + instcombine, and it may just have been luck that this worked). llvm-svn: 119002
