------- Comment #4 from acahalan at gmail dot com 2006-02-20 04:11 ------- It's interesting that you say "__builtin_expect gives the same probability on all targets". I'm not exactly sure what you mean, but I'll guess that you mean it states that the condition will be true X% of the time.
If so, X should be documented. Also: approximately X% or minimum X%? BTW, it seems that this X value might not be correct for all architectures. I guess that would be a different bug though, and the problem may have been fixed by now. It would be nice to have more than one level, including at least "100% certain" and two other levels. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26367
