New Revision: 183805
URL: http://llvm.org/viewvc/llvm-project?rev=183805&view=rev
Log:
Improvements to the data formatters SB API:
- exposing new accessors: formats/format, ..., that allow you to iterate over all formatters
e.g. sys_category = lldb.debugger.GetCategory("system").summary['char *']
- ensuring that C++-based synthetic children provider can at least print their description accurately, if nothing else
