Subject: [PATCH 11/46] [gdb/testsuite] Fix gdb.dwarf2/dw2-fixed-point.exp on
|
||
|
|
arm-linux
|
||
|
|
|
||
|
|
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.
