------- Comment #21 from potswa at mac dot com 2009-09-15 14:56 ------- Just to be clear that "working properly" in this context means "working faster" ;v) .
I just coded up a special case for k = ± 1 that uses std::copy, which should map to memmove for std::vector::iterator. That should beat anything else. When I posted the code I said "for safekeeping." I would like to officially become a contributor :v) but this is taking a fair amount of time and theoretically something could make me drop it but I don't have a job right now so that's unlikely. Also, what happens with std::__gcd? We erase it, right, and leave any surreptitious uses in the cold? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41351
