[LLVMdev] [PATCH] Fix weak/linkonce linkage in execution engine

[Matthieu Moy]

Hi,

I've had problem with a program using LLVM that tried to dynamic_cast
objects created in the JIT execution engine, from the native part of the
program (for the curious, the program is PinaVM
http://gitorious.org/pinavm/pages/Home).

I've narrowed down the issue to the linkage of weak_odr and linkonce_odr
symbols, used for the vtables, and that _must_ be unique for
dynamic_cast to work.

Attached are two patches: the first adds a (failing) testcase, the
second fixes the issue.

I'm not familiar with patch submission on this list, let me know if
there's a better way to submit patches.
