fc4f39b11f MSL: Support native texture_buffer type, throw error on atomics.
Atomics are not supported on images or texture_buffers in MSL.
Properly throw an error if OpImageTexelPointer is used (since it can
only be used for atomic operations anyways).

c51e5b7911 MSL: Add a setting to capture vertex shader output to a buffer.
This will be necessary to support transform feedback, as well as
tessellation shaders.

5345756cab MSL: Support composites inside I/O blocks
I had to refactor the existing add_interface_block as it was
getting extremely large. Now it's all split up into different readable
functions.

1dd676c1de MSL: Emit wrapper for SSign (sign() for int types)
Metal does not define the sign() function for integer types, only
floating-point types.

3a9af9681c MSL: Expand arrays of buffers passed as input.
Even as of Metal 2.1, MSL still doesn't support arrays of buffers
directly. Therefore, we must manually expand them. In the prologue, we
define arrays holding the argument pointers; these arrays are what the
transpiled code ends up referencing. We might be able to do similar
things for textures and samplers prior to MSL 2.0.

Speaking of which, also enable texture arrays on iOS MSL 1.2.

0e9ad14ba6 MSL: Handle the ViewportIndex builtin.
This requires MSL 2.0+.

Also, force `ViewportIndex` and `Layer` to be defined as the correct
type, which is always `uint` in MSL.

Since Metal doesn't yet have geometry shaders, the vertex shader (or
tessellation evaluation shader == "post-tessellation vertex shader" in
Metal jargon) is the only kind of shader that can set this output. This
currently requires an extension to Vulkan, which causes validation of
the SPIR-V binaries for the test cases to fail. Therefore, the test
cases are marked "invalid", even though they're actually perfectly valid
SPIR-V--they just won't work without the
`SPV_EXT_shader_viewport_index_layer` extension.

674f97a40e Handle interpolation qualifiers on the entire struct, too. 2018-09-06 12:29:42 -05:00
Chip Davis
1e51b235af Add tests showing we don't emit interpolation qualifiers in vertex shaders.
In MSL, these only have an effect on fragment `[[stage_in]]` members.
They have no effect in vertex shaders. The Khronos front end doesn't
even emit the SPIR-V decorations for them.

ab21dfb25b Fix execution order for for-loop emission.
In some cases, the compiler decided to emit continue block first,
which invalidated the expressions used by the condition.
Parameters to functions can be evaluated in any order which caused
"random" behavior.

be4cb17a14 Enhance MSL testing and add numerous MSL test cases.
Add to suite of MSL tests and references any existing GLSL tests
that successfully convert GLSL->SPIRV->MSL and compile as MSL.
test_shaders_helper() ignores hidden files that start with '.',
to avoid accidentally finding hidden OSX files such as .DS_Store.
Use xcrun to compile MSL shaders instead of hard-coded path to Metal compiler.
Wrap calls to xcrun in exception handling to ignore if Xcode not installed.
For MSL tests, move call to validate_shader_msl() to after call to
regression_check() to allow a converted MSL shader to be saved for
manual review even if it doesn't successfully compile as MSL.

f45075b08b Validate Metal shaders on OSX with Metal compiler
If we run on a system with Xcode installed to a default path, run Xcode
Metal shader compiler to validate the generated MSL shader.

This uncovers an issue in the existing MSL test - MSL backend currently
does not auto-assign attribute locations, which means that translating
GLSL shader without location layout produces an invalid MSL which
generates "error: 'attribute' index '0' is used more than once".
