Oh? I suppose I should go back and look at the logs, but the way it's written there sure seems to match 5.1.5.1 of the sparcv9 manual: You'll only get carry into the high bit on X - Y if X < Y. In any case, if you meant to fix carry computation for subtraction, you missed changing the 64-bit carry computation too. It is still written the same way before and after my patch, and matches both the expectation I have from the v9 manual and the post-patch code along the 32-bit path. r~
