Vulkan:Allow same-named var in nested scope
ESSL 1.00 spec allows for variable with same name to override outer variable
inside of a nested scope. This change adds new scope to symbol table inside
of a function defintion, but after function parameters for ESSL 1.00
shaders (but not webGL). This prevents an error while parsing.
This also includes some new code in translator to rename any vars that are
redefined between the function body and the function parameters. This
prevents an error later on when the translated shader is then parsed as
a desktop GLSL version.

Vulkan: Rework layout block storage conversion
Previously, a pass over the shader was made, converting shared and
packed interface blocks with block storage to std140. This resulted in
link success between interface blocks with different storage as they
were all translated to std140.
With this change, this pass is removed. The link step proceeds with the
block storage specifiers as seen by GLES, and only upon Vulkan GLSL
shader generation "shared" and "packed" are converted to std140.

Vulkan: add uniform buffer object support
Support for layout qualifiers in interface blocks are added. All
interface blocks are adjusted to either be in std140 or std430.
In the Vulkan backend, a new descriptor set is added for UBOs. A dirty
bit is added for UBO updating and pipeline layouts and descriptor
bindings are updated.

Add flags to shader translator to emulate gl_DrawID
Adds support for translating gl_DrawID for implementation of
GL_ANGLE_multi_draw.
Currently the change only supports and allows emulation of the
draw id using a uniform variable named `gl_DrawID`. This uniform is
mapped in the translated shader to a hashed name that does not
use the gl_ namespace

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)
