This radar extends the notion of one-liner summaries to automagically apply in a few interesting cases More specifically, this checkin changes the printout of ValueObjects to print on one-line (as if type summary add -c had been applied) iff: this ValueObject does not have a summary its children have no synthetic children its children are not a non-empty base class without a summary its children do not have a summary that asks for children to show up the aggregate length of all the names of all the children is <= 50 characters you did not ask to see the types during a printout your pointer depth is 0 This is meant to simplify the way LLDB shows data on screen for small structs and similarly compact data types (e.g. std::pair<int,int> anyone?) Feedback is especially welcome on how the feature feels and corner cases where we should apply this printout and don't (or viceversa, we are applying it when we shouldn't be) llvm-svn: 191996
