Questions

ADT's in gimple dumps

Currently all ADT's get lowered to RECORD or UNION types in GENERIC and then to gimple but even though we are setting TYPE_NAME to the TYPE_DECL the name is empty in -fdump-tree-gimple the debug_tree output seems to be correct also.

Method Resolution Candidate search

Does searching for candidates in method calls require autoderef to filter what impl block might be applicable.

Looks like the documentation has been updated detailing the Probe phase now.
