--- Comment #1 from Richard Biener ---
Confirmed. update-address-taken does, after CCP:
af (int xn)
{
void * D.2359;
- void * _2;
[local count: 1073741824]:
# DEBUG BEGIN_STMT
# DEBUG D.2357 => 4
# DEBUG nq => &xn
# DEBUG BEGIN_STMT
- _4 = &xn;
# DEBUG D.2357 => NULL
# DEBUG nq => NULL
- _2 = _4;
- MEM[(struct cb *)_2] = {};
+ xn_5 = VIEW_CONVERT_EXPR({});
+ # DEBUG xn => xn_5
return;
which failed to "fold" the V_C_E. It does reach
rhs = fold_build1 (VIEW_CONVERT_EXPR,
TREE_TYPE (lhs), rhs);
but this does nothing.
