Hi, builtin_expect should be a NOP in size_estimation. Indeed, the call stmt itself is 0 weight in size and time. But it may introduce an extra relation expr which has non-zero size/time. The end result is: for w/ and w/o builtin_expect, we have different size/time estimation for early inlining. This patch fixes this problem. -Rong
