    • Stencil buffer texture sampling · 1c462ebc
      Alexis Hetu authored 
      In order to perform a blitFramebuffer operation, ANGLE uses
a compute shader which reads the stencil from a depth+stencil
image to a buffer, and then copies this buffer to the stencil
of the other image.

This cl basically treats VK_FORMAT_S8_UINT as VK_FORMAT_R8_UINT
with quad layout for the purpose of texture sampling.

Fixes the following tests:
dEQP-GLES3.functional.fbo.blit.depth_stencil.depth32f_stencil8_basic
dEQP-GLES3.functional.fbo.blit.depth_stencil.depth32f_stencil8_stencil_only
dEQP-GLES3.functional.fbo.blit.depth_stencil.depth24_stencil8_basic
dEQP-GLES3.functional.fbo.blit.depth_stencil.depth24_stencil8_stencil_only

    • Optimize "max(t, t)" to fold into just "t" · a9dc7707
      Sean Risser authored 
      This masks a crash related to nested, unconditional continue statements.
Those constructs are known to be buggy, but we have elected to not fix
them at this point in time because the SWANGLE project will deprecate
all of Swiftshader's GLES backend.

It's unlikely that the remaining bug will effect many end-users as it
relies on bizarre control flow.

For logging purposes here is the shader code that reproduces an infinite
loop:

    void foo() { }

    void main() {
	for (int i = 0; i < 4; i++) {
	    continue;
	    for (int k = 0; k < 4; k++)
		continue;
	    foo();
	}
    }

I'm not adding this as a unit test since we aren't fixing our compiler.
