Oes spec says:
For the both the input array gl_SampleMaskIn[] and the output array gl_SampleMask[], bit B of mask M
(gl_SampleMaskIn[M] or gl_SampleMask[M]) corresponds to sample 32*M+B. These arrays have
ceil(gl_MaxSamples/32) elements, where gl_MaxSamples is the maximum number of color samples
supported by the implementation.
But glslang report error "array must have size before use length".
layout(location = 0) out mediump vec4 fragColor;
void main (void)
{
for (int i = 0; i < gl_SampleMask.length(); ++i)
gl_SampleMask[i] = int(0xAAAAAAAA);
fragColor = vec4(0.0, 1.0, 0.0, 1.0);
}
* Add two test items, one is for gl_MaxSapmles = 32 and the other one is for gl_MaxSapmles = 64.
