            Bug ID: 24520
           Summary: Section names containing forward slash are rejected
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: MC
          Assignee: unassignedbugs at nondot.org
          Reporter: michael.m.kuperstein at intel.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

This is accepted by gcc, but rejected by clang:

void foo() {
  asm volatile(
    ".section bar/buzz\n"
    );
}

I'm not sure whether this is a bug on our side or in gcc. The gas documentation
explicitly says which characters can appear in a symbol names (and slashes are
not on the list), but it's not clear whether this applies to section names.

This isn't a purely theoretical concern, since SeaBIOS actually uses __FILE__
when constructing section names.
