With them uninitialized, the register allocator is free to put them in the same hard register, which results in xmm0 = xmm0 >= xmm0 ? xmm0 : xmm0 Which is of course a nop, but one for which we would ICE splitting the pattern. */ double out; static void foo(void) { double t1, t2, t3, t4; t4 = t1 >= t2 ? t1 : t2; t4 = t4 >= t3 ? t4 : t3; out = t4; }
