The size of an array can be a specialization constant or a spec constant
op. This complicates things quite a lot.
Reflection becomes very painful in the presence of expressions instead
of literals so add a new array which expresses this.
It is unlikely that we will need to do accurate reflection of interface
types which have specialization constant size.
SSBOs and UBOs will for now throw exception if a dynamic size is used since it
is very difficult to know the real size.
Fix some minor missing pieces from C++.
Type remapping like this doesn't seem to fit MSL backend so well, as it
does a lot of remapping internally on its own.
Type name remapping, really is for fringe extension cases in GLSL which
aren't yet supported in SPIR-V.
- Only consider I/O variables if part of OpEntryPoint.
- Keep a safe fallback if #entry-points is 1 to avoid potentially
breaking previously working shaders.
OpName is only for debug information, so we must be very careful that
we do not reuse the same name for different variables.
This was previously done for local variables, but this commit extends
this to global variables as well.
This is supported as compiler extensions, but we can be standards
compliant here, so use the classic workaround of having a single entry
array at the end of the structs instead.
Reformats the entire codebase. Better to do it now than later.
Adds .clang-format and a convenience script format_all.sh which formats
everything automatically.
