This needs some render testing, but is destined to be part of master.
This also leads to a variety of other simplifications.
- IO are global symbols, so only need one list of linkage nodes (deferred)
- no longer need parse-context-wide 'inEntryPoint' state, entry-point is localized
- several parts of splitting/flattening are now localized
- Add new queries: TProgram::getUniformTType and getUniformBlockTType,
which return a const TType*, or nullptr on a bad index. These are valid for
any source language.
- Interface name for HLSL cbuffers is taken from the (only) available declaration name,
whereas before it was always an empty string, which caused some troubles with reflection
mapping them all to the same index slot. This also makes it appear in the SPIR-V binary
instead of an empty string.
- Print the binding as part of the reflection textual dump.
- TType::clone becomes const. Needed to call it from a const method, and anyway it doesn't
change the object it's called on.
- Because the TObjectReflection constructor is called with a TType *reference* (not pointer)
so that it's guaranteed to pass in a type, and the "badReflection" value should use a nullptr
there, that now has a dedicated static method to obtain the bad value. It uses a private
constructor, so external users can't create one with a nullptr type.
Previously, the binding auto-mapping facility was free to use any unused
binding. This change makes auto-bindings use the same offset value as
explicit bindings.
