be904dcc1e Handle collapsed loops similar to collapsed selections. 
If we hit the deprecated scenario of selection with identical branches,
we need to collapse loops into direct branches if need be.

f7e98c39db Avoid detection of false loop variables. 
If the loop variable candidate has a dominating block that lives in an
unrelated loop, we have to reject the loop variable candidate.

06ca9accd7 HLSL: Add option to emit entry point name 1:1 instead of main(). 
MSL backend supports emitting custom name, and there's no reason for
HLSL to not support that as well, but we have to make it an option to
not break existing users.

4185acc70d MSL: Fixes from review for SPV_KHR_physical_storage_buffer extension. 
- Assign ulongn physical type to buffer pointers in short arrays
  when array stride is larger than pointer size.
- Support GL_EXT_buffer_reference_uvec2 casting
  buffer reference pointers to and from uvec2 values.
- When packing structs, include structs inside physical buffers.
- Update mechanism for traversing pointer arrays when calculating type sizes.
- Added unit test shaders.

99f8613847 Fix compilation errors with deprecated sprintf function 
This commit modifies sprintf calls to fix the following compilation
errors using XCode 14.0 beta on MacOS:

> 'sprintf' is deprecated: This function is provided for compatibility
> reasons only.  Due to security concerns inherent in the design of
> sprintf(3), it is highly recommended that you use snprintf(3) instead.

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.
