[LLVMdev] Missing symbols in pass stack trace

[Carlo Alberto Ferraris]

I'm working on a pass (both LLVM and the pass have been compiled in 
debug+asserts mode) but when the pass crashes in the stack trace printed 
by opt the names of the functions inside my pass don't appear (see 
frames 14-16). How can I have them displayed?
