    • Pass ImplFactory to Texture constructor · 82c47ad0
      Olli Etuaho authored 
      This improves encapsulation inside the Texture class, and removes
duplication of createTexture calls. This is a necessary step towards
adding a shared "Data" structure to the Texture classes, following a
similar pattern as for example the Framebuffer class.

This patch also shares the same MockFactory class among different
unit tests.

    • Clean up MipmapTest · b97a3e77
      Olli Etuaho authored 
      This refactoring is done to prepare for adding more mipmap tests for
ES3 where base level / max level is changed from 0.

1. Reuse drawQuad() from ANGLETest instead of having completely custom
quad drawing code, and reuse the same clear+draw function for both 2D
and cube map texture tests.

2. Add a helper function for clearing texture level 0 with glClear.

3. Remove a few redundant texture binding and useProgram calls.

4. Rely on sampler uniforms being set to 0 by default and texture unit
0 being active by default.

5. Remove "Offscreen" from variable names.

6. Split SetUp functions to helper functions.

7. Reuse FillWithRGBA from TextureTest also in MipmapTest.

    • Takes principal component analysis to improve the endpoint in ETC transcode. · 6684007a
      Minmin Gong authored 
      Insteading of getting the BC1 endpoints from the max and min intensity, a PCA
on pixels might give us better quality results, with limited costs.

    • Defer global initializers when necessary · 3d932d83
      Olli Etuaho authored 
      Move global variable initializers that are not constant expressions to
a function that gets called at the start of main(). This is done
with an AST transformation. This needs to be done because global
variable initializers must be constant in native GL, but ANGLE is more
lenient with what can be put into ESSL 1.00 global initializers to
remain compatible with legacy WebGL content.

Non-constant global variable initializers also caused issues in HLSL
output, since in HLSL output some types of expressions get unfolded
into multiple statements. These include short-circuiting operators and
array initialization. To make sure that these cases are covered, any
initializers that can't be constant folded are deferred, even if they
have the const qualifier.

The old deferring mechanism in OutputHLSL is removed in favor of this
new AST transformation based approach.

    • Wrap integer textures with correct wrap mode in HLSL · b079c7af
      Olli Etuaho authored 
      The wrap mode information for all three dimensions is packed to a
single integer in order to conserve sampler metadata space. Only one
int4 vector is used for the metadata for a single sampler.

The sampler metadata is now packed into a struct instead of an array
of integers in order to make the code more readable and maintainable.
The internalFormatBits field is not removed in this patch. It's better
to remove it in a separate patch, so restoring it is easier in case it
will be used for optimizing some of the texture sampling functions.

The wrap mode passed in sampler metadata is used to wrap the texture
coordinates in the code generated to implement ESSL 3.00 integer
texture sampling built-ins.

Those dEQP-GLES3.functional.texture.units.* tests that sample from
integer cube maps still fail on Intel D3D after this change,
presumably due to driver issues.
