problem with gdb and breakpoints

[Kai Schaeffer <kschaeffer at schaeffer-apparatebau dot de>]

Hello,

I got the gdb 4.17 version with the patch for the bdm. But I have a problem
with the address calculation if I want to set breakpoints. To demonstrate
the problem I wrote a little program. In the gdb I get the following file
info:

(gdb) info file
Symbols from "/root/bdm/test/a.out".
Local exec file:
        `/root/bdm/test/a.out', file type coff-m68k.
        Entry point: 0x100400
        0x00100000 - 0x00100bd8 is .text
        0x00100bd8 - 0x00100bdc is .data
        0x00100bdc - 0x00103ec0 is .bss 

This is correct. So I can download the program and it runs. Here is the
listing (I know there is no sense in this program :-)

(gdb) list 1,12
1       int test(int i)
2       {
3         return i+1;
4       }
5
6       main()
7       {
8         int i;
9         for (i=0;i<10;i++) {
10          test(i);
11        }
12      } 

Everything seems perfect until I try to set a breakpoint:

(gdb) break 8
Breakpoint 1 at 0xa: file main.c, line 8.
(gdb) break 3
Breakpoint 2 at 0x4: file main.c, line 3. 

The gdb tries to set the breakpoints at wrong addresses. It seems to me,
that the offset of the line to the beginning of the corresponding function
will be used. These breakpoints doesn't work.

If I try to set a breakpoint in this way:

(gdb) break test
Breakpoint 3 at 0x1004ec: file main.c, line 12.

The address is correct, but the line is wrong. This breakpoint works.

Does someone have an idea ?


Thank you 

Kai
