Add support for standalone GC back compatibility #78484
Conversation
Currently, the version of the standalone GC has to match the version that the runtime was compiled with. This change enables loosening that requirement. Runtime is allowed to use any standalone GC as long as its version is larger or equal to a defined minimum version. GC is now passed the version of GC the runtime was compiled with and it can use it to behave in a way compatible with that version. For example, if we add new methods to the GC to EE interface, that GC can check the GC version the runtime supports and skip calling the new methods if it is running with an older runtime.
