For this bug to trigger, we need a gimple statement:
- without side-effects
- with one SSA_OP_DEF result (which also needs to be an SSA_NAME)
- with an SSA_OP_VDEF result
The case you mention doesn't have an SSA_OP_DEF, so that one is caught by this
check:
...
def_p = SINGLE_SSA_DEF_OPERAND (stmt, SSA_OP_DEF);
if (def_p == NULL)
return false;
...
