We want to be able to recover when fix storage class is not able to fix
everything, and just leave the spir-v in an invalid state. The pass
should not fail because of that.
This removes some uses of the type manager. One use could not be
removed. Instead I had to update GenCopy to not use the type manager,
and be able to copy pointers.
Part of #5691
The SPIR-V specification allows any scalar integer type as an index. DXC
usually emits indexes as 32-bit integer types, however, in some cases it
is possible to make it emit 64-bit indexes instead (as in
https://github.com/microsoft/DirectXShaderCompiler/issues/5638).
Add functionality to fix-storage-class so that it can fix up mismatched
data types for pointers as well.
Fixes bugs in when fixing up storage class.
Move GenerateCopy to the Pass class to be reused.
The spirv-opt change for #2535.
This pass tries to fix validation error due to a mismatch of storage classes
in instructions. There is no guarantee that all such error will be fixed,
and it is possible that in fixing these errors, it could lead to other
errors.
Fixes#2430.
