In particular, for pointers GetNumChildren justrecursively calls itself on the pointee type, so it effectively walks chains ofpointers. This is different from the logic of GetChildAtIndex, which onlyrecurses if pointee.IsAggregateType() returns true (IsAggregateType is false forpointers and references), so it never follows chain of pointers.This patch aims to make GetNumChildren (more) consistent with GetChildAtIndex byonly recursively calling GetNumChildren for aggregate types.Ideally, GetNumChildren and GetChildAtIndex would share the code that decideswhich pointers/references are followed, but that is a bit more invasive change.Reviewers: teemperor, jingham, clayborgReviewed By: teemperor, clayborgSubscribers: clayborg, labath, shafik, lldb-commitsTags: #lldbDifferential Revision: https://reviews.llvm.org/D80254 List of files: /llvm-project-15.0.7/lldb/test/API/functionalities/pointer_num_children/Makefile Mon, 25 May 2020 09:17:48 +0000 Jaroslav Sevcik <jarin@google.com>
