2) providing an updated list of tagged pointers values for the objc_runtime module - hopefully this one is final 3) changing ValueObject::DumpValueObject to use an Options class instead of providing a bulky list of parameters to pass around this change had been laid out previously, but some clients of DumpValueObject() were still using the old prototype and some arguments were treated in a special way and passed in directly instead of through the Options class 4) providing new GetSummaryAsCString() and GetValueAsCString() calls in ValueObject that are passed a formatter object and a destination string and fill the string by formatting themselves using the formatter argument instead of the default for the current ValueObject 5) removing the option to have formats and summaries stick to a variable for the current stoppoint after some debate, we are going with non-sticky: if you say frame variable --format hex foo, the hex format will only be applied to the current command execution and not stick when redisplaying foo the other option would be full stickiness, which means that foo would be formatted as hex for its whole lifetime we are open to suggestions on what feels "natural" in this regard llvm-svn: 151801
