gdb-4.95.1 problem with weak functions

[Dan Nicolaescu <dann at godzilla dot ICS dot UCI dot EDU>]

Hi!

It seems that gdb-4.95.1  does not display correctly the function when
stoping in weak functions. 


It stops in a function that is defined as weak, not in the function
that is actualy run... 


here is an example:

--FILE t.c
int test_weak (void) __attribute__ ((weak));
   
int 
test_weak (void) 
{
  return 1;
}  
   
int
test (void)
{  
  return test_weak ();
}  
--END

--FILE main.c
int test (void);
   
int
test_weak (void)
{  
  return 2;
}  
   
int
main (void)
{  
  int val;
  val =  test ();
  printf ("val = %d\n", val);
  return val;
}  
--END

compile them with gcc-2.95.2 on sparc-sun-solaris2.7

(gdb) b test_weak
Breakpoint 1 at 0x1094c: file t.c, line 6.
(gdb) r
Starting program: /home/dann/hacks/weak/a.out 


Breakpoint 1, test_weak () at t.c:6
6         return 1;
(gdb) 
(gdb) c
Continuing.
val = 2

Program exited with code 02.


the breakpoint should have been set in main.c, not in t.c
the debugger realy stoped the program, but did not display the correct
file name and line number of the function being executed (should have
been main.c)
