           Summary: inline assembly warnings are treated as errors
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: cdavis at mymail.mines.edu
                CC: llvmbugs at cs.uiuc.edu


A simple test case with this unimplemented CFI directive:

$ cat inline-asm.c

asm(".cfi_adjust_cfa_offset 4\n\t");

produces this:

$ clang -c inline-asm.c
<inline asm>:1:1: error: warning: ignoring directive for now
.cfi_adjust_cfa_offset 4
^
1 error generated.

It's clearly a warning, yet clang reports it as an error. Aside from the
obvious point that someone needs to finish up CFI support, I don't think that
warnings should be reported as errors unless -Werror gets passed to the
compiler.
