7dcfed888a Use a hook to emit a local for the sample position.
That way, we don't have to handle it specially when constructing a call.

39bc101e82 MSL: Handle the SamplePosition builtin.
This is somewhat tricky, because in MSL this value is obtained through a
function, `get_sample_position()`. Since the call expression is an
rvalue, it can't be passed by reference, so functions get a copy
instead.

This was the last piece preventing us from turning on sample-rate
shading support in MoltenVK.

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.

41eb5c43b5 MSL: Fix OpAtomicIIncrement and OpAtomicIDecrement.
We were passing a constant '1' to `emit_atomic_func_op()`--which caused
us to refer to SPIR-V value `%1`, which is almost certainly not what we
want! What we really want is to add/subtract the literal constant '1'
to/from the memory location.

Merge pull request #684 from cdavis5e/msl-builtin-vector-cast
MSL: Cast uses of builtin vectors to their declared SPIR-V type.
2018-09-11 19:59:58 +02:00
Chip Davis
6757ef8512 Use bitcast_to_builtin_load() instead of hacking to_expression().
This only affects the builtin when it is used, and not when it's passed
to a function. It's a lot cleaner than the way I was doing it before.

Remove the `to_expression()` hack.

f7dad9da66 MSL: Cast uses of builtin vectors to their declared SPIR-V type.
In SPIR-V, builtin integral vectors can be either signed or unsigned,
but in MSL they're always unsigned. Unfortunately, the MSL spec forbids
implicit conversions between vector types--even if the corresponding
scalar types would implicitly convert. If you try, the result is a
cryptic error message such as:

```
program_source:37:60: error: cannot convert between vector values of different size ('int4' (aka 'vector_int4') and 'vector_uint4' (vector of 4 'unsigned int' values))
            float4 r3 = as_type<float4>((as_type<int4>(r0) * gl_LocalInvocationID.xyyy) + as_type<int4>(r2));
                                         ~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~
```

Therefore, uses of these builtins must be explicitly cast, since the
rest of the binary likely assumes that the builtin is of its declared
type.

4b99fdd5d0 MSL: Account for components when assigning locations to varyings.
Two varyings (vertex outputs/fragment inputs) might have the same
location but be in different components--e.g. the compiler may have
packed what were two different varyings into a single varying vector.
Giving both varyings the same `[[user]]` attribute won't work--it may
yield unexpected results, or flat out fail to link. We could eventually
pack such varyings into a single vector, but that would require us to
handle the case where the varyings are different types--e.g. a `float`
and a `uint` packed into the same vector. For now, it seems most
prudent to give them unique `[[user]]` locations and let Apple's
compiler work out the best way to pack them.

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.

even emit the SPIR-V decorations for them.

separate meta blocks. Fix this by always redirecting parameter naming to
the original base variable as necessary.

Move arrays and structs out to their own global static constants.

Also, replace illegal names in HLSL as well.

09f550f718 Handle exponential explosion of code-gen during first phase of compile.
Certain patterns with OpVectorShuffle (and probably others) will cascade
to so large, that they can cause OOM. After we have observed
force_recompile, don't spend unnecessary memory emitting code which will
never be used.

d4e470babd Analyze the CFG for temporaries as well.
Normally, temporary declaration must dominate any use of it,
so we generally did not need to analyze the CFG for these variables,
but there is an edge case where you have an inliner doing:

do {
	create_temporary;
	break;
} while(0);

use_temporary;

The inside of the loop dominates the outer scope, but we cannot emit
code like this in GLSL, so make sure we hoist these temporaries outside
the "loop".
