// Ensure no regression on ARM/gcc compatibility for
// emitting explicit symbol relocs for nonexternal symbols
// versus section symbol relocs (with offset) -
//
// Default llvm behavior is to emit as section symbol relocs nearly
// everything that is not an undefined external. Unfortunately, this
// diverges from what codesourcery ARM/gcc does!
//
// Tests that reloc to .L.str* show up as explicit symbols
