[LLVMdev] Need help reproducing a sanitizer buildbot failure

[Diego Novillo]

OK, so now I've gotten a build but the output from asan is less than
helpful:

$ llvm/x/llvm_build_asan/./bin/opt
llvm/x/llvm/test/Other/optimization-remarks-inline.ll
-inline -pass-remarks=inline -S
=================================================================

Is there an option for asan to show me source file locations?  Or at least
function names.  I'm not sure what to do with this.


Thanks.  Diego.
