eb580d6656 Ensure that we use primary alias type when emitting flattened members. 2020-07-29 13:02:25 +02:00

aac6885950 GLSL: Be more aggressive about using type_alias. 
To facilitate an improved linking-by-name use case for older GL,
we will be more aggressive about merging struct definitions, even for
rather unrelated cases where we don't strictly need to use type aliases.

57c93d44ac GLSL: Add option to force flattening IO blocks. 
It is not always desirable to use actual blocks.
A prime example in the case where EXT_shader_io_blocks is not supported
on the target implementation.

fa5b206d97 MSL: Workaround broken vector -> scalar access chain in MSL. 
On MSL, the compiler refuses to allow access chains into a normal vector type.
What happens in practice instead is a read-modify-write where a vector type is
loaded, modified and written back.

The workaround is to convert a vector into a pointer-to-scalar before
the access chain continues to add the scalar index.

4d79d634f5 GLSL: Implement switch on ESSL 1.0. 
Cannot use switch on legacy ESSL, fallback to plain branches.

bae76d7915 GLSL: Use for-loop fallback instead of do/while for legacy ESSL. 
do/while loops are not guaranteed to be supported in ESSL 1.0 / OpenGLES
2.0 implementations.

3afbfdb090 Implement context-sensitive expression read tracking. 
When inside a loop, treat any read of outer expressions to happen
multiple times, forcing a temporary of said outer expressions.
This avoids the problem where we can end up relying on loop-invariant code motion to happen in the
compiler when converting optimized shaders.

05188aca69 Fix bug with control dependent expression tracking.

eb0f0323d3 HLSL: Workaround FXC bugs with degenerate switch blocks. 
When we see a switch block which only contains one default block, emit a
do {} while(false) statement instead, which is far more idiomatic and
readable anyways.

03d4bcea68 MSL: Improve handling of array types in buffer objects. 
When loading and storing array types which belong to buffer objects, we
need to treat these values as not being value types. Also, need to
handle array load/store from/to more address space combinations.

5281d9997e MSL: Fix up input variables' vector lengths in all stages. 
Metal is picky about interface matching. If the types don't match
exactly, down to the number of vector components, Metal fails pipline
compilation. To support pipelines where the number of components
consumed by the fragment shader is less than that produced by the vertex
shader, we have to fix up the fragment shader to accept all the
components produced.

There is no native formulation, so introduce a concept of a "complex"
bitcast to handle odd-ball cases which have no native unary operation.

f8592ecdfc MSL: Deal correctly with initializers on Private variables. 
Do not attempt to defer declaration. It would happen to work in most
cases, but the edge case is where the first thing that happens to a
variable is being OpStore'd into.
