Purpose:
glsl spec allows to define array with the length of the result of constant expression, the arithmetic operation of "mod(float (7.1), float (4.0))" should be generate the array length at the shader compile time,
but glslang didn't support mod operation for the constant expression in previous implementation;
An example is as following:
###########
#version 460
flat out highp int vtx_out_out0;
void main (void)
{
float array[int(mod(float (7.1), float (4.0)))];
vtx_out_out0 = array.length();
}
