--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I see first real code changes between r11-5028 and r11-5029 during fre3 which
optimizes away some rereads of current_value.m in _dl_lookup_symbol_x, which
passes its address to other functions.
# DEBUG BEGIN_STMT
# PT = nonlocal escaped null
_47 = current_value.m;
_48 = _47->l_used;
_49 = _48 == 0;
...
_335 = val.m;
- # PT = nonlocal escaped null
- _336 = current_value.m;
- if (_335 != _336)
+ if (_47 != _335)
...
<bb 204> [local count: 3147328]:
- # PT = nonlocal escaped null
- _383 = current_value.m;
- iftmp.45_384 = _383->l_map_start;
+ iftmp.45_384 = _47->l_map_start;
...
- # PT = nonlocal escaped null
- _120 = current_value.m;
<bb 217> [local count: 114862414]:
# PT = nonlocal escaped null
- # _66 = PHI <0B(30), _116(153), _120(216)>
+ # _66 = PHI <0B(30), _116(153), _47(216)>
(plus of course since the modref pass points to info changes).
