           Summary: mixed disassemble does not work for a function in
                    included file
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
        AssignedTo: unassigned@sourceware.org
        ReportedBy: anemo@mba.ocn.ne.jp


If a function body was in included file, disassemble with /m option does not
work.

--- foo.c ---
#include "foo2.c"
int main(int argc, char **argv)
{
    int a = foo2(argc);
    return a;
}
--- foo2.c ---
int foo2(int x)
{
    return x + 1;
}
---

$ gcc -o foo -g foo.c
$ gdb ./foo
GNU gdb (GDB) 7.2.50.20101214-cvs
...
(gdb) disassemble /m main
Dump of assembler code for function main:
...
4        int a = foo2(argc);
   0x08048390 <+17>:    mov    (%ecx),%eax
   0x08048392 <+19>:    mov    %eax,(%esp)
   0x08048395 <+22>:    call   0x8048374 <foo2>
   0x0804839a <+27>:    mov    %eax,-0x8(%ebp)
...
End of assembler dump.
(gdb) disassemble /m foo2
Dump of assembler code for function foo2:
End of assembler dump.
(gdb) disassemble foo2
Dump of assembler code for function foo2:
   0x08048374 <+0>:    push   %ebp
   0x08048375 <+1>:    mov    %esp,%ebp
   0x08048377 <+3>:    mov    0x8(%ebp),%eax
   0x0804837a <+6>:    add    $0x1,%eax
   0x0804837d <+9>:    pop    %ebp
   0x0804837e <+10>:    ret    
End of assembler dump.
(gdb) list foo2
1    int foo2(int x)
2    {
3        return x + 1;
4    }

Normal disassemble command and list command works fine, but mixed disassemble
command does not work.
