           Summary: JIT DWARF EH data does not seem to emit LSDA
           Product: new-bugs
           Version: trunk
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: csdavec at swan.ac.uk
                CC: llvmbugs at cs.uiuc.edu

Calling _Unwind_GetLanguageSpecificData() from a personality function returns
NULL in JIT'd frames.  At least some of the EH data is being correctly emitted,
because the correct personality function is being called (this personality
function is only referenced in JIT'd code, so the fact that it's called at all
tells me something).  Statically compiling the same IR works fine.

I think this used to work, but unfortunately it's not a feature that I use very
often so I didn't notice exactly when my test started to fail.
