            Bug ID: 40035
           Summary: --size-sort causes symbols to not print
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-nm
          Assignee: unassignedbugs at nondot.org
          Reporter: rupprecht at google.com
                CC: llvm-bugs at lists.llvm.org

Using "--size-sort" seems to prevent symbols from printing in llvm-nm. Adding
"-S" fixes it but it should not be necessary.

$ echo 'int foo; int bar() { return 5; }' | clang -xc -c - -o /tmp/foo.o
$ nm --size-sort /tmp/foo.o
0000000000000004 C foo
000000000000000b T bar
$ llvm-nm --size-sort /tmp/foo.o
<no output>
$ llvm-nm -S --size-sort /tmp/foo.o
0000000000000004 0000000000000004 C foo
0000000000000000 000000000000000b T bar
