cf1bf1c6ae Update external/ to SPIR-V 1.5 
Rolled the hashes used for glslang, SPIRV-Tools, and SPIRV-Headers to
HEAD, which includes the update to 1.5.

Added passing '--amb' to glslang, so I didn't have to explicitly set
bindings in a large number of test shaders that currently don't, and
now glslang considers them invalid.

Marked all shaders that no longer pass spirv-val as .invalid.

e4c6388571 More fixes to handling packing & access elements in an array. Made in two parts. 1. Don't allow AccessChain operations to add duplicated swizzles when accessing packed arrays. 2. Only pack arrays when there is the proper amount of space between members in a struct, otherwise it will definitely be wrong. 2019-09-11 16:15:10 -04:00

869d628521 The result of an AccessChain intrinsic in SPIRV can be referenced by multiple blocks but when they are loops that can result in compilation problems because the source variables might not be declared early enough. This forces us to hoist those variables high enough to make it work. 2019-09-11 14:01:40 -04:00

a80c74b40e There are occasions where phi-variable copies are introduced for original variables which are fully declared, which coud result in the phi-variable never being declared and the shader not compiling, so declare the phi-variables when this happens. Change made in two parts. 1. Ensure that we declare phi-variable copies even if the original declaration isn't deferred. 2. Only flush phi variables once, avoids duplicate definitions. 2019-09-11 14:00:49 -04:00

2af70b837c When converting from HLSL the dxc SPIRV output often contains variables that are written through (e.g. a = b = c;) which seems to break the tracking of expressions in SPIRV-Cross, so don't reset everything once configured. 2019-09-10 13:25:20 -04:00

9e54a8dd7b Slight modifications to IAB support for Metal output, so that the caller can specify an offset for the IAB start index, as for HLSL shaders UAVs need to occupy slots 0-7. The runtime support for SSBO robustness is also much simpler if the buffer size block is at index 0. Change made in two parts. 1. Allow the caller to specify the Metal translation should use argument buffers. 2. Move this to the front of IABs for convenience of the runtime. 2019-09-10 13:09:49 -04:00

d9f3576305 Metal doesn't automatically enforce robust access to buffers unlike other APIs, so for storage-buffers, which become raw T* buffers in Metal, we need to fetch the buffer size and clamp the access to a valid index within the buffer ourselves. This is essential for shaders converted from HLSL which expects all resource access to be robust, though this implementation is technically different to the HLSL specification of return-0 for OOB reads, ignore OOB writes. 2019-09-10 12:32:32 -04:00

0428faada3 HLSL makes position calculations invariant by default to eliminate problems with depth-precision, Apple added a similar qualifier for Metal 2.1 that can and should be used in Vertex & Domain/TessEval shaders for the same effect. 2019-09-10 11:47:40 -04:00

9ce3158193 When compiling from HLSL which pads and aligns float[]/float2[] within structures to float4[] we need to unpack the original type in Metal from the float4. 2019-09-10 11:21:43 -04:00

42b8a62870 Fixes to the generation of Metal tessellation shaders from SPIRV so that it works correctly in more complicated cases. 
First, when generating from HLSL before invoking the code that comes from the HLSL patch-function a control-flow and full memory-barrier are required to ensure that all the temporary values in thread-local storage for the patch are available.
    Second, the inputs to control and evaluation shaders must be properly forwarded from the global variables in SPIRV to the member variables in the relevant input structure.
    Finally when arrays of interpolators are used for input or output we need to add an extra level of array indirection because Metal works at a different granularity than SPIRV.

    Five parts.
    1. Fix tessellation patch function processing.
    2. Fix loads from tessellation control inputs not being forwarded to the gl_in structure array.
    3. Fix loads from tessellation evaluation inputs not being forwarded to the stage_in structure array.
    4. Workaround SPIRV losing an array indirection in tessellation shaders - not the best solution but enough to keep things progressing.
    5. Apparently gl_TessLevelInner/Outer is special and needs to not be placed into the input array.

de6441af88 Work-around HLSL using zero-based InstanceID and VertexID variables, but SPIRV, like Metal, includes BaseInstance & BaseVertex. Until this can be fixed in DXC, which is really the proper place to solve this, we can decrement InstanceID & VertexID when the source is HLSL. Made in two parts. 1. Handle HLSL-style 0-based vertex/instance index. 2. We zero-base the InstanceID & VertexID variables for HLSL emulation elsewhere, so don't do it twice. 2019-09-09 16:55:59 -04:00

97a66ff906 On iOS sub-passes can be implemented using the frame-buffer fetch API which is much more efficient than binding the textures. Change was made in three parts. 1. Use Metal's native frame-buffer fetch API for subpass inputs. 2. Make sure that frame-buffer-fetch is only available on iOS. 3. Default to using Metal's native frame-buffer fetch for subpass inputs on iOS. 2019-09-09 15:02:11 -04:00

32557e9093 SPIRV doesn't distinguish depth textures from regular textures, but Metal does, so if we've ever seen a depth comparison operation we must ensure that the texture is specified as a depth-texture. 2019-09-06 16:58:27 -04:00
