--- Comment #14 from fdlbxtqi <euloanty at live dot com> --- I think It is worth the effort to rewrite these functions since they are so fundamental to the performance of entire C++. What I am worry about is that whether revamping these functions would be a new ABI breaking. If it won’t, I would like to contribute my implementation.

I would rather see the library does the optimization instead of the > compiler. I do not trust the compiler can always optimize this stuff. If we have both, that looks even safer ;-) -- You are receiving this mail because: You are on the CC list for the bug. You reported the bug.
