            Bug ID: 22558
           Summary: pic jump tables should not be executable on ELF
           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: rafael.espindola at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

ELF has relocations to represent

   bar - foo

even if bar is in another section. This allows for the table to be output in a
non executable section even with -fPIC.
