    • Generate performance warnings in HLSL translation · 89a69a03
      Olli Etuaho authored 
      Generate performance warnings for some code that undergoes heavy
emulation when translated to HLSL:
1. Dynamic indexing of vectors and matrices.
2. Non-empty fall-through cases in switch/case.

The warnings are generated only when code is translated to HLSL.
Generating them in the parsing stage would add too much maintenance
burden.

Improves switch statement fall-through handling in cases where an
empty fall-through case follows a non-empty one so that extra
performance warnings are not generated.

    • Remove unnecessary work from VariablePacker · 4cd889ec
      Olli Etuaho authored 
      The VariablePacker does not check the staticUse flag, variables should
be pre-filtered according to their staticUse flag before passing them
to CheckVariablesInPackingLimits if that's desired.

The names of the variables are also not relevant to the packing. We
keep the "name" field to make the code easier to debug, but updating
the mappedName is not useful.

This will make implementing arrays of arrays simpler.

    • Add more complete NULL driver for the GL back-end. · 6d94f064
      Jamie Madill authored 
      This implements a NULL driver in OpenGL by stubbing out most of the
GL functions in FunctionsGL except a few static "Gets" that are needed
for initialization with Chromium and the tests. It is intended to be
used for performance testing ONLY and will not have correct behaviour.

It also adds a define to enable conditionally excluding the null entry
points for implementations that wish to save on a bit of binary size.

Also fixes some of the typedefs in functionsgl_typesdefs.h that were
turned up after implementing the direct assignment from NULL stub
entry point, generated from gl.xml, to the function pointer with type
defined from functionsgl_typedefs.h.

    • Add an auto-generated dispatch table for GL bindings. · 29ddcc99
      Jamie Madill authored 
      This will more easily allow us to extend our implementation to make a
NULL or "stub" set of bindings. It also exposes a lot more function
permutations via extension variations.

It might improve the loading speed for bindings obtained via
extensions. Instead of generating a list every time an extension is
checked, we use a single std::set for a fast query. However because
more extensions are checked for more entry points, it might not make
a huge difference.

This also fixes an issue where the "real" ANGLE GL headers were being
propagated to the entry point dispatch table definitions, instead of
being in a totally isolated file. This patch adds the missing typedefs
to our proxy headers.

It also fixes the naming of a few entry points which was inconsistent
with the spec. It also makes an XML adjustment to GL_NV_path_rendering
to accomodate a hole in the spec where glLoadMatrixfEXT was not ever
defined in OpenGL ES. A spec oddity with the TexStorage extension is
not resolved - in this case, some methods are only exposed if other
extensions are present, but this information is missing from gl.xml.

    • Vulkan: Implement basic uniforms. · 76e471e9
      Jamie Madill authored 
      This implementation adds one descriptor set with two bindings: one for
default vertex uniforms and the other for fragment. It adds two
corresponding uniform buffers, and the logic for updating the
descriptor sets bound to Vulkan. It doesn't handle much in the way of
synchronization and dependency management, or uniform update.

If there are only vertex or fragment uniforms the empty uniform buffer
is omitted from the descriptor set. If both are missing, there is no
descriptor set bound.

Note that as our implementation progresses we might not be able to
initialize our descriptor sets at link time, due to streaming in
uniform data.
