[RFC] proposed 'lem' patch to improve behaviour under emulation

2012-12-27 Thread Luigi Rizzo
This patch implements two features for the 'lem' driver that greatly improve the throughput under proper hypervisor. This is joint work with Vincenzo Maffione and Giuseppe Lettieri, I am posting it here for review, will then commit it if there are no objections. The first change is to implement

clang 3.2 RC2 miscompiles libgcc?

2012-12-27 Thread Stefan Farfeleder
Hi, I noticed that most of my C++ applications in recent versions of FreeBSD head suddenly crash without me recompiling them. I tracked it down to r243830 which imported a new clang version. The new clang seems to compile libgcc in a wrong or at least incompatible way with what gcc expects. In fac
