Summary:
Match the ordering semantics of non-vector comparisons. For
floating point comparisons that do not correspond to instructions, the
tests check that some vector comparison instruction was emitted but do
not care about the full implementation.

Summary:
Since the shuffle mask is not exposed as an operand in the native ISel
DAG, create a new WebAssembly ISD node exposing the mask. The mask is
lowered as sixteen immediate byte indices no matter what type the
original vector shuffle was operating on.
This CL depends on D51656

Summary:
Splats are fewer bytes than v128.consts, so use them when either could
apply.

Summary:
Reorganize WebAssemblyInstrSIMD.td to put all of the instruction
definitions together, making it easier to see which instructions have
been implemented already. Depends on D51143.

WebAssemblyInstrFormats.td retains only multiclasses that are used in
multiple other tablegen files.

Summary:
This CL adds support for arbitrary BUILD_VECTORS, i.e. not splats and
not consts. This is the last feature needed to properly lower v2i64
multiplies without a i64x2.mul instruction (which is not in the spec),
so i64x2.mul is removed as well.

Remove unnecessary condition and fix whitespace
llvm-svn: 340472
Summary:
This CL implements v128.const for each vector type. New operand types
are added to ensure the vector contents can be serialized without LEB
encoding. Tests are added for instruction selection, encoding,
assembly and disassembly.

Implement instruction selection for all versions of the extract_lane
instruction. Use explicit sext/zext to differentiate between
extract_lane_s and extract_lane_u for applicable types, otherwise
default to extract_lane_u.

llvm-svn: 339707
Add missing SIMD types (v2f64) and binary ops. Also adds
tablegen support for automatically prepending prefix byte to SIMD
opcodes.

We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Summary:
* Add 64-bit address space feature.
* Rename SIMD feature to SIMD128.
* Handle single-thread model with an IR pass (same way ARM does).
* Rename generic processor to MVP, to follow design's lead.
* Add bleeding-edge processors, with all features included.
* Fix a few DEBUG_TYPE to match other backends.
