| ; Test case to show that -x86-pad-for-align causes binary differences in the |
| ; presence of debug locations. Inputs/pad-align-with-debug.s and |
| ; Inputs/pad-align-without-debug.s are equivalent, modulo a single .loc, which |
| ; cause the difference in the binary below. This should be fixed, before |
| ; x86-pad-for-align=true becomes the default. |
