As part of routine testing, I run clang and llvm-gcc a lot of times. Something happened between r83681 and r84167 such that clang-cc and cc1 became many hundreds of times slower when asked to perform optimizations. Is this a known issue? These are all release builds on Ubuntu Jaunty on x86. During these long runs, memory usage creeps up slowly at maybe 1 MB per minute. Thanks, John Regehr

My InlineCost refactoring has been noticed in this aspect; that may or may notbe the culprit here. A quick thing you can do is to compile with -ftime-report and compare the top few passes between versions.

Some plots fail due to a problem with the X11 fonts. I get a message that "X11 font at size 22 could not be loaded." The demo() graphics routine for instance dies during the third chart. The graphics demo calls "font.main=1" and that seems to be where the error is. I believe this is due to a configuration problem on my system, however I can't find where in the

This is new to 2.3.1 (and to 2.3.0 i suppose), i.e. everything worked like a charm in 2.2.1; it looks like a bug to me (but might notbe), and I have not been able to find any reference to such a problem in the archives (which is strange, but I might have got blind). Any idea pls? Thanks a lot in advance Ensemble adoptons des gestes responsables : N'imprimez ce mail que si necessaire. Les informations contenues dans ce messa...

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
