Derek Schuff	75834f76b2	[WebAssembly] Initial SIMD128 support. ... Kicks off the implementation of wasm SIMD128 support (spec: https://github.com/stoklund/portable-simd/blob/master/portable-simd.md), adding support for add, sub, mul for i8x16, i16x8, i32x4, and f32x4. The spec is WIP, and might change in the near future.

Duncan P. N. Exon Smith	a3dcb9e3b4	WebAssembly: Avoid implicit iterator conversions, NFC ... Avoid implicit conversions from MachineInstrBundleIterator to MachineInstr* in the WebAssembly backend by preferring MachineInstr& over MachineInstr*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@274912 91177308-0d34-0410-b5e6-96231b3b80d8	2016-07-08 19:36:40 +00:00
Dan Gohman	4c8fe28374	[WebAssembly] Reintroduce ARGUMENT moving logic ... Reinteroduce the code for moving ARGUMENTS back to the top of the basic block. While the ARGUMENTS physical register prevents sinking and scheduling from moving them, it does not appear to be sufficient to prevent SelectionDAG from moving them down in the initial schedule. This patch introduces a patch that moves them back to the top immediately after SelectionDAG runs. This is still hopefully a temporary solution. http://reviews.llvm.org/D14750 is one alternative, though the review has not been favorable, and proposed alternatives are longer-term and have other downsides. This fixes the main outstanding -verify-machineinstrs failures, so it adds -verify-machineinstrs to several tests.
