           Summary: llvm-gcc doesn't take advantage of __const_coal section
                    on darwin
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org
                CC: llvmbugs at cs.uiuc.edu


Building instcombine at -O0 -g with llvm-gcc, nothing is emitted into the
__const_coal section.  With GCC, it emits:

        Section (__DATA, __const_coal): 48
        Section (__TEXT, __const_coal): 128

I don't know what this section is, but if useful, we should use it. :)
