2012-01-24add ::drop_back() and ::drop_front() methods, which are like ↵Chris Lattner
pop_front/pop_back on a vector, but a) aren't destructive to "this", and b) can take a # elements to drop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148791 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-24switch SCEV to use the new ConstantFoldLoadThroughGEPIndices functionChris Lattner
instead of its own hard coded thing, allowing it to handle ConstantDataSequential and fixing some obscure bugs (e.g. it would previously crash on a CAZ of vector type). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148788 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-24Split the interesting bits of ConstantFoldLoadThroughGEPConstantExprChris Lattner
out into a new ConstantFoldLoadThroughGEPIndices (more useful) function and rewrite it to be simpler, more efficient, and to handle the new ConstantDataSequential type. Enhance ConstantFoldLoadFromConstPtr to handle ConstantDataSequential. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148786 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-24Revert r148686 (and r148694, a fix to it) due to a serious layeringChandler Carruth
violation -- MC cannot depend on CodeGen. Specifically, the MCTargetDesc component of each target is actually a subcomponent of the MC library. As such, it cannot depend on the target-independent code generator, because MC itself cannot depend on the target-independent code generator. This change moved a flag from the ARM MCTargetDesc file ARMMCAsmInfo.cpp to the CodeGen layer in ARMException.cpp, leaving behind an 'extern' to refer back to it. That layering order isn't viable givin the constraints outlined above. Commandline flags are designed to be static specifically to avoid these types of bugs. Fixing this is likely going to require some non-trivial refactoring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148759 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-23convert CAZ, UndefValue, and CPN to use DenseMap's again, this time withoutChris Lattner
