ES31: Add atomic_uint support to HLSL translator
This is the first commit in a series to enable atomic counter buffers.
Adds support for atomic counters to the GLSL->HLSL translator using
RWByteAddressBuffer.

Support GL_OES_texture_border_clamp
Added support for GL_TEXTURE_BORDER_COLOR and GL_CLAMP_TO_BORDER in
OpenGL/OpenGLES, Direct3D9 and Direct3D11 backends.
For integer textures in OpenGLES3 contexts these additional entry points
are available now:
void glTexParameterIivOES(enum target, enum pname, const int *params);
void glTexParameterIuivOES(enum target, enum pname, const uint *params);
void glGetTexParameterIivOES(enum target, enum pname, int *params);
void glGetTexParameterIuivOES(enum target, enum pname, uint *params);
void glSamplerParameterIivOES(uint sampler, enum pname, const int *params);
void glSamplerParameterIuivOES(uint sampler, enum pname, const uint *params);
void glGetSamplerParameterIivOES(uint sampler, enum pname, int *params);
void glGetSamplerParameterIuivOES(uint sampler, enum pname, uint *params);

ES31: Support shader storage block in D3D11 compiler - Part1
This patch is the first step to implement a basic skeleton to translate
shader storage block to HLSL RWByteAddressBuffer.
In GLSL each shader storage block is just one structured block and in API side
it corresponds to a buffer range where stores the whole structure.
RWStructuredBuffer is an array-like object and can have many structured
elements. The structured element doesn't support unsized array and also have
a small limitation on the element size. So we choose RWByteAddressBuffer as
the counterpart of shader storage block in HLSL.
Due to RWByteAddressBuffer does not support using an index to reference a
specific location, we must use Load and Store to process the read/write
operation of a buffer variable. Moreover, in the compiler tree, since we
can't use variable name to get the resource value in RWByteAddressBuffer,
we have to calculate the offset of buffer variable in a shader storage block,
then call the corresponding wrapper function to get the right value.
In this patch, we only process below situations:
assign_to_ssbo := ssbo_access_chain = expr_no_ssbo;
assign_from_ssbo := lvalue_no_ssbo = ssbo_access_chain;
The translation is like below:
// GLSL
#version 310 es
layout(local_size_x=8) in;
layout(std140, binding = 0) buffer blockA {
float f[8];
} instanceA;
layout(std140, binding = 1) buffer blockB {
float f[8];
};
void main()
{
float data = instanceA.f[gl_LocalInvocationIndex];
f[gl_LocalInvocationIndex] = data;
}
// HLSL
RWByteAddressBuffer _instanceA: register(u0);
RWByteAddressBuffer _blockB: register(u1);
float float_Load(RWByteAddressBuffer buffer, uint loc)
{
float result = asfloat(buffer.Load(loc));
return result;
}
void float_Store(RWByteAddressBuffer buffer, uint loc, float value)
{
buffer.Store(loc, asuint(value));
}
void gl_main()
{
float _data = float_Load(_instanceA, 0 + 16 * gl_LocalInvocationIndex);
float_Store(_blockB, 0 + 16 * gl_LocalInvocationIndex, _data);
}
We will do below things in the following patches:
1. Modify the intermediate tree to flatten all ssbo usages to:
assign_to_ssbo := ssbo_access_chain = expr_no_ssbo;
assign_from_ssbo := lvalue_no_ssbo = ssbo_access_chain;
e.g.
intanceA.a +=1;
->tmp = intanceA.a;
intanceA.a = tmp + 1;
while(++instanceA.a < 16) {
}
->
int PreIncrement(out int a)
{
a += 1;
return a;
}
tmp = instanceA.a;
while(PreIncrement(tmp) < 16) {
instanceA.a = tmp
}
2. Add offset calculation for structure and array of arrays.
TODOs have been marked in the corresponding places in this patch.
3. Improve helper functions so that they can process all possible types.
TODOs have been marked in the corresponding places in this patch.
4. Process the swizzle situation.
TODOs have been marked in the corresponding places in this patch.
A possible method is to extend current helper functions like below:
*_Load(RWByteAddressBuffer buffer, uint loc, bool isSwizzle, uint4 swizzleOffset)

Rename UniformHLSL to ResourcesHLSL
In future, atomic counter and shader storage block will be added into UniformHLSL since
they all need the UAV register. So this change renames UniformHLSL to ResourcesHLSL.
