With test-case gdb.dwarf2/dw2-fixed-point.exp on arm-linux I run into:
...
(gdb) PASS: gdb.dwarf2/dw2-fixed-point.exp: set lang ada
print pck.fp1_var^M
$1 = 0.3125^M
(gdb) FAIL: gdb.dwarf2/dw2-fixed-point.exp: print pck.fp1_var
...
The problem is that the thumb prologue analyzer overshoot, setting the
breakpoint for main after line 49:
...
46 int
47 main (void)
48 {
49 pck__fp1_var++;
...
and consequently we see the value of pck.fp1_var after line 49 instead of
before line 49. This is PR tdep/31981.
Work around this by removing line 49 and all similar subsequent lines, which
turn out to be dead code.
