The basic idea here is that all functions will have a list of which
combinations of parameters will be combined inside the function.
The caller will then know which combined samplers must be provided to
the callee in order to satisfy it.
- 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.
type_id was not intuitive and did not allow for parsing array sizes of
variables.
Expose another member, base_type_id which will provide the base type
suitable for parsing metadata such as decorations and type_id will now
point to the actual type which includes full type information such as
arrays and so on.
There was a potential problem if variables were invalidated and SPIR-V
read expressions which depended on other expression which in turn depended on the
invalidated variable.
Also fixes issue where variables were considered immutable if they were
forwardable. This allowed some incorrect optimizations to slip through.
Add Decoration qualified_alias element.
Virualize Compiler to_name() function.
MSL use qualified_alias instead of alias when inside entry-point function.
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.
