Didn't fail at beginning of September, 2012.  Fail is specific to -Os.
Comment 1 John David Anglin 2012-12-09 15:59:24 UTC 
(gdb) p for_val2
$2 = 6
(gdb) p goto_val
$3 = 11
(gdb) p for_val1
$4 = 12
(gdb) p for_val2
$5 = 6
(gdb) p goto_val
$6 = 11
(gdb) p ifelse_val1
$7 = 31
(gdb) p ifelse_val2
$8 = 23
(gdb) p ifelse_val3
$9 = 246
(gdb) p switch_val
$10 = 55

for_val2 and goto_val are wrong.
Comment 2 Richard Biener 2013-01-07 15:29:07 UTC 
Needs more analysis from someone with pa access.  Or maybe it works again?
Comment 3 John David Anglin 2013-01-08 01:27:48 UTC 
I don't this anymore (after r194549).
