Bob Wilson 5e8b833707 Add ARM patterns to match EXTRACT_SUBVECTOR nodes. ... Also fix an off-by-one in SelectionDAGBuilder that was preventing shuffle vectors from being translated to EXTRACT_SUBVECTOR. Patch by Tim Northover. The test changes are needed to keep those spill-q tests from testing aligned spills and restores. If the only aligned stack objects are spill slots, we no longer realign the stack frame. Prior to this patch, an EXTRACT_SUBVECTOR was legalized by loading from the stack, which created an aligned frame index. Now, however, there is nothing except the spill slot in the stack frame, so I added an aligned alloca. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122995 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-07 04:59:04 +00:00
