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

5e8590a23d Emulate texture atomics in Metal by binding the underlying buffer that backs the resource to a separate binding point and using that for Metal's atomic operations. This will work with texture_buffer and texture2d created from an MTLBuffer, so is perfect for emulating HLSL atomics on RWBuffer and sufficient, but not ideal, for RWTexture2D with some restrictions (limited format support and can't be used for render-targets). 2019-09-05 15:13:28 -04:00

239e04762b Support Metal 2.1's texture_buffer type which is the equivalent to HLSL's Buffer/RWBuffer, so doesn't require modifying buffer sizes to match alignments. 2019-09-05 14:46:15 -04:00

8596bf5ee2 In order to use Metal shader libraries properly you have to ensure that you have no duplicated global symbol names for different entities, otherwise 'metallib' won't be able to combine multiple shaders into a single library. This is broken into two parts. 1. Constant arrays of non-primitive types (i.e. matrices) won't link properly into Metal libraries. 2. Metal helper functions must be static force-inline otherwise they will cause problems when linked together in a single Metallib. 2019-09-05 14:39:06 -04:00

d50659af92 Rework the way arrays are handled in Metal to remove the array copies as they are unnecessary from Metal 1.2. There were cases where copies were not being inserted and others appeared unncessary, using the template type should allow the 'metal' compiler to do the best possible optimisation. The changes are broken into three stages. 1. Allow Metal to use the array<T> template to make arrays a value type. 2. Force the use of C style array declaration for some cases which cannot be wrapped with a template. 3. Threadgroup arrays can't have a wrapper type. 4. Tweak the code to use unsafe_array in a few more places so that we can handle passing arrays of resources into the shader and then through shaders into sub-functions. 5. Handle packed matrix types inside arrays within structs. 6. Make sure that builtin arguments still retain their array qualifiers when used in leaf functions. 7. Fix declaration of array-of-array constants for Metal so we can use the array<T> template. 2019-09-05 12:39:44 -04:00

39dce88d3b MSL: Add support for sampler Y'CbCr conversion.
This change introduces functions and in one case, a class, to support
the `VK_KHR_sampler_ycbcr_conversion` extension. Except in the case of
GBGR8 and BGRG8 formats, for which Metal natively supports implicit
chroma reconstruction, we're on our own here. We have to do everything
ourselves. Much of the complexity comes from the need to support
multiple planes, which must now be passed to functions that use the
corresponding combined image-samplers. The rest is from the actual
Y'CbCr conversion itself, which requires additional post-processing of
the sample retrieved from the image.

Passing sampled images to a function was a particular problem. To
support this, I've added a new class which is emitted to MSL shaders
that pass sampled images with Y'CbCr conversions attached around. It
can handle sampled images with or without Y'CbCr conversion. This is an
awful abomination that should not exist, but I'm worried that there's
some shader out there which does this. This support requires Metal 2.0
to work properly, because it uses default-constructed texture objects,
which were only added in MSL 2. I'm not even going to get into arrays of
combined image-samplers--that's a whole other can of worms.  They are
deliberately unsupported in this change.

I've taken the liberty of refactoring the support for texture swizzling
while I'm at it. It's now treated as a post-processing step similar to
Y'CbCr conversion. I'd like to think this is cleaner than having
everything in `to_function_name()`/`to_function_args()`. It still looks
really hairy, though. I did, however, get rid of the explicit type
arguments to `spvGatherSwizzle()`/`spvGatherCompareSwizzle()`.

Update the C API. In addition to supporting this new functionality, add
some compiler options that I added in previous changes, but for which I
neglected to update the C API.

df18d98bea MSL: Unify the get_*_address_space() methods.
These methods have largely the same logic, with minor differences. That
I felt compelled to duplicate the logic into another method was one of
the things that bothered me about the variable pointers change. This
cleans that part of the code up; now we don't have two places to change.

This is not allowed as we cannot take mutable reference to a

fb5ee4cb5c MSL: Adjust BuiltInWorkgroupId for vkCmdDispatchBase().
This command allows the caller to set the base value of
`BuiltInWorkgroupId`, and thus of `BuiltInGlobalInvocationId`. Metal
provides no direct support for this... but it does provide a builtin,
`[[grid_origin]]`, normally used to pass the base values for the stage
input region, which we will now abuse to pass the dispatch base and
avoid burning a buffer binding.

`[[grid_origin]]`, as part of Metal's support for compute stage input,
requires MSL 1.2. For 1.0 and 1.1, we're forced to provide a buffer.

(Curiously, this builtin was undocumented until the MSL 2.2 release. Go
figure.)
