New Revision: 198655<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=198655&view=rev" target="_blank">http://llvm.org/viewvc/llvm-<u></u>project?rev=198655&view=rev</a><br>
Log:<br>
Implement a new -fstandalone-debug option. rdar://problem/15685848<br>
It controls everything that -flimit-debug-info used to, plus the<br>
vtable type optimization. The old -fno-limit-debug-info option is now an<br>
alias to -fstandalone-debug and vice versa.<br>
<br>
Standalone is the default on Darwin until dtrace is updated to work with<br>
non-standalone debug info (rdar://problem/15758808).<br>
<br>
Note: I kept the LimitedDebugInfo name in CodeGenOptions::DebugInfoKind<br>
because NoStandaloneDebugInfo sounded even more confusing.<br>

+Clang supports a number of optimizations to reduce the size of debug<br>
+information in the binary. They work based on the assumption that the<br>
+debug type information can be spread out over multiple compilation<br>
+units. For instance, Clang will not emit type definitions for types<br>
+that are not needed by a module and could be replaced with a forward<br>
+declaration. Further, Clang will only emit type info for a dynamic<br>
+C++ class in the module that contains the vtable for the class.<br>
+<br>
+The B<-fstandalone-debug> option turns off these optimizations. This<br>
+is useful when working with 3rd-party libraries that don't come with<br>
+debug information. Note that Clang will never emit type information<br>
for types that are not referenced at all by the program.<br>
