David Blaikie c3f30a7fc6 Reapply: DebugInfo: Assume an absence of ranges or high_pc on a CU means the CU is empty (devoid of code addresses) ... Originally committed in r349333, reverted in r349353. GCC emitted these unconditionally on/before 4.4/March 2012 Clang emitted these unconditionally on/before 3.5/March 2014 This improves performance when parsing CUs (especially those using split DWARF) that contain no code ranges (such as the mini CUs that may be created by ThinLTO importing - though generally they should be/are avoided, especially for Split DWARF because it produces a lot of very small CUs, which don't scale well in a bunch of other ways too (including size)). The revert was due to a (Google internal) test that had some checked in old object files missing DW_AT_ranges. That's since been fixed. llvm-svn: 349968		2018-12-21 22:25:01 +00:00
