...er functions. TargetInfo handles platform-specific details, and we have target-specific subclasses of that class. The subclasses override functions defined in TargetInfo. The TargetInfo member functions are called multiple times for each relocation. So the cost of virtual function calls may be non-neglible. That is a motication to do the following test. As a test, I removed all TargetInfo subclasses except for x86-64, move all code from X86_64TargetInfo to TargetInfo, and remove `virtual` from TargetInfo. The original LLD links itself (with debug info) in 7.499 seconds. The de-virtualized version...

...r to get all results, I have to copy the loop out of the function and paste it into R directly. 2) It is very, very slow. For a dataset of 62,000 rows and 253 list entries, it takes probably 5 minutes on a pentium D. An implementation of this kind of subsetting using hashtables in C# takes a neglible amount of time. I am open to any suggestions about data format, methods, anything. Thanks, Iestyn Lewis Emory University

Hello everyone, I've been looking through the libvirt API to get information about memory page dirtying of VMs. I need these to aid decisions on which VM to migrate. The only thing I found is virDomainGetJobStats() with VIR_DOMAIN_JOB_MEMORY_DIRTY_RATE but that only works when a migration is already running. Is there a way to get information on VMs which are not already migrating? Thanks

Hi all, most of the freedesktop.org servers just got new kernels, so they'll be rebooted tomorrow (Monday) morning UTC. Sorry for the short notice, downtime should be neglible. Regards, -- Tollef Fog Heen UNIX is user friendly, it's just picky about who its friends are

...whole program optimization or simple per translation unit optimization, but the performance difference is so small that it's nearly lost in the measurement noise. Moving the mmx intrinsic functions into the mmxstate.c file and declaring them as static inline made a bigger difference (still neglible). Cheers, Nils

...between the SmallString and the stream by making the SmallString private to the class. This however did not treat the root problem, the duplication of the information about the buffer between SmallString and the stream. I can make performance measurements but even if the performance difference is neglible (and looking at all the code paths and conditionals of non-inlined functions at raw_ostream.cpp that's hard to believe), the current SmallString-raw_svector_ostream is simply wrong. Personally, after the previous "Alp" discussion I found and fixed several such issues in my out-of-tr...

hi wxrubiers firstly - im right in understanding there is no gem for x86_64? failing that i''ve been trying to compile, but am failing because ld cant find lwx_gtk2u_aui-2.8 im on ubuntu (gutsy) and have wx-windows2.8 headers installed as well as libwxbase2.8dev and libwxgtk2.8-dev can anyone help? thanks glenn
