D3D: fix uniform block alignment error
If the uniform block will be translated to HLSL StructuredBuffer,
in order to follow the std140 rules, we should add padding between
the members if necessary.

D3D: throw a perf warning for uniform block
We had translated an uniform block only containing a large array member
into StructuredBuffer instead of cbuffer on D3D backend for slow fxc
compile performance issue with dynamic uniform indexing.
This patch throw a warning if a uniform block containing a large array
member fails to hit the optimization.

Restrict to translate uniform block to StructuredBuffer
We had translated an uniform block only containing a large array member
into StructuredBuffer instead of cbuffer on D3D backend for slow fxc
compile performance issue with dynamic uniform indexing.
Now we add more conditions to restrict the translation. Only indexing
operator is allowed to operate on this uniform block variable. And we
also restrict the types of uniform block's member.

Restrict member types for StructuredBuffer
Std140 storage layout has some rules for uniform block, must
pad StructuredBuffer element type explicitly to match std140
layout rules when translating std140 uniform block to
StructuredBuffer. In this CL, restrict member types which are
not needed to add paddings according std140 layout rules.

Translate uniform block with large matrix array to StructuredBuffer
There is a slow compiling issue if translate a uniform block with
a large matrix array member to cbuffer, so translate the uniform
block to StructuredBuffer. But pack_matrix pragma directive is
invalid for matrix element of StructuredBuffer, so pack the matrix
into a structure firstly, and then specifies packing alignment for
the matrix in this structure, last the structure is used as
StructuredBuffer element.

Implement Draw base vertex and base instance functions
This patch implements functionality of glDrawArraysInstancedBaseInstanceANGLE,
glDrawElementsInstancedBaseVertexBaseInstanceANGLE,
glMultiDrawArraysInstancedBaseInstanceANGLE,
and glMultiDrawElementsInstancedBaseVertexBaseInstanceANGLE
Workaround for OpenGL driver on Mac:
gl_VertexID on Mac with AMD GPU doesn't include baseVertex value.
So replace gl_VertexID with (gl_VertexID + angle_BaseVertex) if any.
Workaround for Vulkan GLSL:
gl_InstanceIndex on Vulkan includes baseInstance. So replace
gl_InstanceIndex with (gl_InstanceIndex - angle_BaseInstance) when
angle_BaseInstance is declared.

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)
