Justin Holewinski	d1c0859c87	Propagate DAG node ordering during type legalization and instruction selection ... A node's ordering is only propagated during legalization if (a) the new node does not have an ordering (is not a CSE'd node), or (b) the new node has an ordering that is higher than the node being legalized. llvm-svn: 177465	2013-03-20 00:10:32 +00:00
Justin Holewinski	9a248309f0	[NVPTX] Disable vector registers ... Vectors were being manually scalarized by the backend. Instead, let the target-independent code do all of the work. The manual scalarization was from a time before good target-independent support for scalarization in LLVM. However, this forces us to specially-handle vector loads and stores, which we can turn into PTX instructions that produce/consume multiple operands. llvm-svn: 174968	2013-02-12 14:18:49 +00:00
