15b52bee48 Deal with packing/unpacking on store.
Still a bit buggy, since we cannot deduce between float2[] and
packed_float2. Need a deeper refactor to plumb this through ...

d92de00cc1 Rewrite how IDs are iterated over.
This is a fairly fundamental change on how IDs are handled.
It serves many purposes:

- Improve performance. We only need to iterate over IDs which are
  relevant at any one time.
- Makes sure we iterate through IDs in SPIR-V module declaration order
  rather than ID space. IDs don't have to be monotonically increasing,
  which was an assumption SPIRV-Cross used to have. It has apparently
  never been a problem until now.
- Support LUTs of structs. We do this by interleaving declaration of
  constants and struct types in SPIR-V module order.

To support this, the ParsedIR interface needed to change slightly.
Before setting any ID with variant_set<T> we let ParsedIR know
that an ID with a specific type has been added. The surface for change
should be minimal.

ParsedIR will maintain a per-type list of IDs which the cross-compiler
will need to consider for later.

Instead of looping over ir.ids[] (which can be extremely large), we loop
over types now, using:

ir.for_each_typed_id<SPIRVariable>([&](uint32_t id, SPIRVariable &var) {
	handle_variable(var);
});

Now we make sure that we're never looking at irrelevant types.

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)

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.

ec857f6778 Cast uses of Layer and ViewportIndex to the expected type. 2018-09-19 09:13:30 -05:00
Chip Davis
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.

d310060f92 MSL: Support global I/O block and struct Input/Output usage.
Implement this by flattening outputs and unflattening inputs explicitly.
This allows us to pass down a single struct instead of dealing with the
insanity that would be passing down each flattened member separately.

Remove stage_uniforms_var_id.
Seems to be dead code. Naked uniforms do not exist in SPIR-V for Vulkan,
which this seems to have been intended for. It was also unused elsewhere.

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.

27af716c3a MSL: Emit F{Min,Max,Clamp} as fast:: and N{Min,Max,Clamp} as precise::.
This roughly matches their semantics in SPIR-V and MSL. For `FMin`,
`FMax`, and `FClamp`, and the Metal functions `fast::min()`,
`fast::max()`, and `fast::clamp()`, the result is undefined if any
operand is NaN. For the 'N' operations and their corresponding MSL
`precise::` functions, the result is consistent with IEEE 754 (first
non-NaN wins; result is NaN if all operands are NaN).

We can only do this with 32-bit floats, though, because Metal only
provides these variants for `float`. `half` only has one variant of
these functions that is presumably consistent with IEEE 754. I guess
that's OK; the SPIR-V spec only says that `F{Min,Max,Clamp}` are
undefined for NaNs. Performance might suffer, though.
