             Bug #: 13262
           Summary: Hide artificial inlines (at least by default)
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jakub@redhat.com
    Classification: Unclassified


As discussed in http://gcc.gnu.org/ml/gcc-patches/2011-10/msg00348.html
and for further info see
http://gcc.gnu.org/ml/gcc-patches/2007-08/msg02300.html
and following thread, it doesn't seem GDB hides by default artificial inline
functions.  glibc and gcc *intrin*.h headers use the artificial attribute
extensively where those inlines shouldn't be visible to the user during single
stepping and backtrace.

extern __inline __attribute__
((__always_inline__,__artificial__,__gnu_inline__)) char *
__attribute__ ((__nothrow__)) strcpy (char *__restrict __dest, __const char
*__restrict __src)
{
  return __builtin___strcpy_chk (__dest, __src, __builtin_object_size (__dest,
2 > 1));
}

char buf[6];
int main(int argc, char **argv)
{
  strcpy (buf,"hello ");
  asm volatile ("" : : : "memory");
  return 0;
}

IMHO the hiding should be just the default behavior, with a way to enable
seeing them in backtraces and seeing them on step through.
