[PATCH] D7895: Anonymous namespaces are missing import DW_TAG_imported_module.

[Robinson, Paul via llvm-commits]

Sorry I wasn't clear - I was referring to the ABI lowering of C++ by value parameters.

struct foo { foo(const foo&); int i; };
struct bar { int i; };
void func(foo, bar) { }

foo and bar are passed quite differently in the ABI

And the formal parameters are described quite differently in the DWARF, meaning the debugger doesn't need special knowledge of the ABI to interpret the DWARF correctly.  I still don't see how this is relevant to the discussion at hand.
