            Bug ID: 31484
           Summary: Emit @object instead of @function when using prefix
                    data
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Common Code Generator Code
          Assignee: unassignedbugs at nondot.org
          Reporter: demiobenour at gmail.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

There is no good reason to emit symbols with type @function when prefix data is
being emitted: the linker will redirect pointers to such symbols through a
trampoline, and the trampoline does not have the prefix data next to it.

This is one of the reasons that GHC needs a mangler that post-processes
LLVM-generated assembly.
