https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=210093 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kib@FreeBSD.org --- Comment #2 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Bulat from comment #1) Earlier assignment is performed only under invariants, i.e. in the debugging kernel. Later one is for the normal control flow. So yes, for the invariants-enabled kernel the second assignment is excessive, but there is no point of optimizing for INVARIANTS, which performs lot of algorithmically unneeded work to make more robust checks. -- You are receiving this mail because: You are the assignee for the bug.home | help
