David Blaikie e2cf6dc5c9 DebugInfo: Elide lexical scopes which only contain other (inline or lexical) scopes. ... DW_TAG_lexical_scopes inform debuggers about the instruction range for which a given variable (or imported declaration/module/etc) is valid. If the scope doesn't itself contain any such entities, it's a waste of space and should be omitted. We were correctly doing this for entirely empty leaves, but not for intermediate nodes. Reduces total (not just debug sections) .o file size for a bootstrap -gmlt LLVM by 22% and bootstrap -gmlt clang executable by 13%. The wins for a full -g build will be less as a % (and in absolute terms), but should still be substantial - with some of that win being fewer relocations, thus more substantiall reducing link times than fewer bytes alone would have. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216861 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-31 21:26:22 +00:00
