Giffuni changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ache@FreeBSD.org, | |pfg@FreeBSD.org --- Comment #2 from Pedro F. Giffuni --- (In reply to jhoward from comment #1) Hi; I am CC'ing Andrey Chernov as he has done changes in qsort(3). The change is interesting, but it has to be benchmarked first. Perhaps you = can try the tests in lib/libc/tests/stdlib/ and see how the compare to the exis= ting code? FWIW, ministat(1) is welcome too ;). Also, we generally don't touch the stuff in contrib until the changes are reviewed by upstream maintainers. --=20 You are receiving this mail because: You are the assignee for the bug.=
