            Bug ID: 33663
           Summary: clang doesn't emit debugging information when
                    compiling assembly files directly to an executable
           Product: new-bugs
           Version: 4.0
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: mike.benfield at gmail.com

If I compile an assembly file (with -g) to an object file, then link the object
file, debugging works correctly. But if I compile an assembly file (with -g)
directly to an executable, it apparently doesn't have debugging information.
Since this is different behavior than when clang compiles C language files, I
believe this is a bug. Example:

$ cat trash.s
.intel_syntax noprefix

.text
        .global _main
_main:
        mov     rax, 5
        ret
$ clang -g trash.s
$ lldb a.out
(lldb) target create "a.out"
Current executable set to 'a.out' (x86_64).
(lldb) breakpoint set -f trash.s -l 6
Breakpoint 1: no locations (pending).
WARNING:  Unable to resolve breakpoint to any actual locations.
