*	Revert r302938 "Add LiveRangeShrink pass to shrink live range within BB."	Hans Wennborg	2017-05-18	1	-1/+1
\| \| \| \| \| \| \| \| \|	This also reverts follow-ups r303292 and r303298. It broke some Chromium tests under MSan, and apparently also internal tests at Google. llvm-svn: 303369
*	Add LiveRangeShrink pass to shrink live range within BB.	Dehao Chen	2017-05-12	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Summary: LiveRangeShrink pass moves instruction right after the definition with the same BB if the instruction and its operands all have more than one use. This pass is inexpensive and guarantees optimal live-range within BB.

*	[NVPTX] Unify vectorization of load/stores of aggregate arguments and return ↵	Artem Belevich	2017-02-21	1	-4/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	values. Original code only used vector loads/stores for explicit vector arguments. It could also do more loads/stores than necessary (e.g v5f32 would touch 8 f32 values). Aggregate types were loaded one element at a time, even the vectors contained within. This change attempts to generalize (and simplify) parameter space loads/stores so that vector loads/stores can be used more broadly. Functionality of the patch has been verified by compiling thrust test suite and manually checking the differences between PTX generated by llvm with and without the patch. General algorithm: * ComputePTXValueVTs() flattens input/output argument into a flat list of scalars to load/store and returns their types and offsets. * VectorizePTXValueVTs() uses that data to create vectorization plan which returns an array of flags marking boundaries of vectorized load/stores. Scalars are represented as 1-element vectors. * Code that generates loads/stores implements a simple state machine that constructs a vector according to the plan.
