Folks use FreeBSD for real work -- I have a window of opportunity to install a new world + kernel. When I tried updating this laptop in early August the kernel build was broken. It appeared broken again this time. The issue is you added a new feature to the GCC compiler (r255185 2013-09-03), and then immediately consumed it in the kernel build (r255187 2013-09-03 11:31:23). You did not put anything in UPDATING warning folks of this. Robert Watson used to often remind folks that when we add features to the toolchain we give a reasonable amount of time for them to work their way into folks userland before using them in the kernel build. My userland sources are from Sunday September 1st when I started my 'make buildworld' + 'mergemaster -p' + 'make installworld' + 'mergemaster -i' sequence. Sorry it takes so long to build world with clang on a T60. I updated my kernel sources and tried to build a new kernel before rebooting. I had no reason to not expect a 2 day old compiler could not build a kernel during a code freeze. I've backed out r255440 as r255452. Please add a note to UPDATING. -- -- David (obrien@FreeBSD.org)
