The problem is that gr6 is not initialized in the interval from the function entry till the jump. I also attach the debug dumps from my backend. The basic block in question is shortcirc_done.1 (line 198 in the log). It starts with: %reg1060 = phi %reg1032, mbb<shortcirc_next.0.selectcont.selectcont, The predecessor is at line 155 and the register 1032 is assigned a value on line 140 (in shortcirc_next.0.selectcont): %reg1032 = move %reg103 After register allocation t...
