           Summary: clang/llvm-gcc/llc wrong section flags output nobits vs
                    progbits
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: edwintorok at gmail.com

$ llvm-gcc -Wno-unused-value -S ioremap.i -S -o -|grep bss
  .bss
        .bss
        .bss
        .section        .bss.page_aligned,"aw", at progbits
        .bss

$ clang -Wno-unused-value -S ioremap.i -S -o -|grep bss
section        .bss.page_aligned,"aw", at progbits
        .bss
        .bss
        .bss

$ gcc -Wno-unused-value -S ioremap.i -S -o -|grep bss
.section        .bss.page_aligned,"aw", at nobits


So it outputs the wrong flags for bss.page_aligned, and also puts some symbols
into .bss, while gcc doesn't put any symbols there.
