52c7c2dab6 MSL: Add support for SPV_KHR_physical_storage_buffer extension. 
- Determine sizing and alignments of pointers to types as
  distinct from the size and alignment of the types themselves.
- Declare all buffer pointers in the MSL device address space.
- Support struct pointer recursion, where structs can
  contain pointers to themselves or to a parent struct.
- Add SPIRType::was_forward_referenced to track if a type was forward
  referenced, to help emit MSL structs in the correct dependency order.
- Handle pointers to pointers that are not just arrays of arrays.

Attempt to overwrite SSA inputs in OpCompositeInsert
 2022-05-18 19:22:36 +02:00

d08ce828f4 Promote Unreachable cases into break to avoid fallthrough. 
HLSL is very fussy about fallthrough in switch blocks, so promote
Unreachable blocks to breaks if they are inside a switch construct.

Some false positives are possible in weird multi-break scenarios, but
this is benign.

23662668dd Attempt more optimal codegen for OpCompositeInsert. 
Speculate that we can modify the SSA value in-place. As long as it is
not used after the modify, this is fine.

Also need to make sure we don't attempt to RMW something that is
impossible to modify.

in OpLoad, similar to builtins.

Implement more proper semantics for RelaxedPrecision vs mediump

7a6c2da9aa GLSL: Handle more proper semantics for RelaxedPrecision. 
GLSL and RelaxedPrecision are quite different in what they affect.
RelaxedPrecision affects operations, while this is merely implied in
GLSL based on inputs.

This leads to situations where we have to promote mediump inputs to
highp, and the simplest approach is to force highp temporaries for
inputs which are consumed in a highp context. For completeness, we also
demote RelaxedPrecision inputs to mediump variables.

PHI is handled by copying the PHI into a temporary.

We have to be very careful with hoisted temporaries, since the child
temporary will not be analyzed up-front. We inherit the hoisted-ness
state and emit the hoisted child temporary as necessary. When faking the
temporaries with OpCopyObject, we make sure to block any variable
hoisting.

Hoisting children of PHI variables is fine, since PHIs are not hoisted with
the same framework as other temporaries.
