------- Comment #37 from bonzini at gnu dot org 2008-05-12 16:48 -------
Ok, I started a bootstrap of the obvious patch on i686-pc-linux-gnu. But I
think the obvious patch is not enough if we go this way. The comments in
simplify_plus_minus are already not up-to-date, and removing CONST is
"interesting" enough that the comment should be updated with clear explanations
(e.g. based on the info H-P gave in PR36182). Would you please do so since you
have better hold on this than I do?
Otherwise, as I said, I have absolutely no problem going for the target-only
fix in 4.4+ too.
