            Bug ID: 30333
           Summary: Asan fails when linking with -Wl,--no-undefined
           Product: clang
           Version: 3.8
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

When linking a target like this:

clang <stuff> -fsanitize=address -Wl,--no-undefined

it will error out due to missing asan symbols. For the same command line GCC
links without errors which makes sense because -fsanitize=address implies the
use of asan libraries.

Please make clang also add the necessary libs automatically when using
-fsanitize=address. Thanks.
