    • Remove dynamic indexing of matrices and vectors in HLSL · 5d91dda9
      Olli Etuaho authored 
      Re-re-relanding after clang warning fix.

Re-re-landing with fix to setting qualifiers on generated nodes. The
previous version failed when a uniform was indexed, because it would
set the uniform qualifier on some of the generated nodes and that
interfered with the operation of UniformsHLSL.

Re-landing after fixing D3D9 specific issues.

HLSL doesn't support dynamic indexing of matrices and vectors, so replace
that with helper functions that unroll dynamic indexing into switch/case
and static indexing.

Both the indexed vector/matrix expression and the index may have side
effects, and these will be evaluated correctly. If necessary, index
expressions that have side effects will be written to a temporary
variable that will replace the index.

Besides dEQP tests, this change is tested by a WebGL 2 conformance test.

In the case that a dynamic index is out-of-range, the base ESSL 3.00 spec
allows undefined behavior. KHR_robust_buffer_access_behavior adds the
requirement that program termination should not occur and that
out-of-range reads must return either a value from the active program's
memory or zero, and out-of-range writes should only affect the active
program's memory or do nothing. This patch clamps out-of-range indices so
that either the first or last item of the matrix/vector is accessed.

The code is not transformed in case the it fits within the limited subset
of ESSL 1.00 given in Appendix A of the spec. If the code isn't within
the restricted subset, even ESSL 1.00 shaders may require this
workaround.

    • D3D11: Add dynamic geometry shaders. · 4e31ad55
      Jamie Madill authored 
      The geometry shader we want will depend on our current draw mode, and
if we're using flat shading in the shader. Without flat shading, we'll
still be using them only for point sprites, but for other primitive
types with flat shading enabled, we'll be using them to correct the
provoking vertex order with D3D11.

Note: no new features in this CL, those are turned on in follow-ups.

    • Refactor Geometry Shader support to enable pass-through. · 76f8fa66
      Jamie Madill authored 
      This should be a refactoring change only. The new code is exercised in
follow-up CLs.
