>> Originally, the allocated size is >> >> sizeof (struct rtvec_def) + ((NELT) - 1) * sizeof (rtx) Yes, this is correct, good catch. >> (sizeof (struct rtvec_def) + sizeof (rtx) - 1) / sizeof (rtx) + >> ((NELT) - 1) // (3) Due to the way those macros expand, right now replacing the first arg with "1" and the second one with straightforward "sizeof (struct rtvec_def) + ((NELT) - 1) * sizeof (rtx)" will work and will be easier to read than division. Liang, would you submit such patch? Thanks again, -- Laurynas
