I'm trying to build an app with clang against libraries that are using GCC 4.1 ABI. I'm getting an error "weakref declaration must have internal linkage" Now I'm stumped though, perhaps it is an incompatibility between clang trunk and gcc 4.1 include files? - I've built clang from trunk - fixed include paths to point to gcc 4.1 include paths When I modify clang to use

Hi, A quick bench-mark of an R matrix muliplication 500by500 X 500by10000, all random variates, with matlab reveals a huge difference in speed (5 times at least). Is there anything that can be done in R to speed up the multiplication?

I have been trying to figure out how glusterfs-fuse client will handle it when 1 of 3 bricks in a 3-way replica is slower than the others. It looks like a glusterfs-fuse client will send requests to all 3 bricks when accessing a file. But what happens when one of the bricks is not responding in time? We saw an issue when we added external load to the raid volume where the brick was located. The

We need something that can do this using static analysis... Otherwise we can just use Eclipse

An easier way would be to use a coverage tool like gcov to see what's actually *used* when the app is run normally. Then you can ask the question, what percentage of all lines of code are dead? A static analysis will not be able to see through things like virtual method calls. Reid On Sun, Jul 3, 2011 at 3:07 PM, Øyvind Harboe <oyvind.harboe at zylin.com> wrote: > Can llvm

Hi Øyvind, > I'm trying to find some written evidence to present to the powers > that be that clang/llvm is ABI compatible with GCC 4.1 linux > 64 bit. both clang and gcc-4.1 are supposed to conform to the platform ABI (if they don't then that is a bug), and thus be ABI compatible. Ciao, Duncan.

Can llvm generate warnings for unused C++ code using global analysis? If I could use llvm to figure out what code I can delete in a 20 year old app with millions of lines of code, this alone would defend spending time on making the app build with llvm, even if we don't actually run the code generated... -- Øyvind Harboe - Can Zylin Consulting help on your project?

I think what you're looking for is something like Doxygen or CodeViz that can generate (imperfect) call graphs for you. It sounds like you just need a rough list of functions that might be unused to start with. -Scott On Sun, Jul 3, 2011 at 11:04 PM, Daniel Berlin <dberlin at dberlin.org> wrote: > On Mon, Jul 4, 2011 at 1:42 AM, Øyvind Harboe <oyvind.harboe at zylin.com>

Hi, For those attending FOSDEM either as volunteer or as a participant, we are looking for interesting presentations about CentOS. If you're interested for one or more topics, please contact me. The deadline for the proposal is Tuesday 23 january 2007. In our developers room (that we share with Fedora) we have about 6 slots of 50mins available that we can divide in 12 slots of 20mins if

Hi, I'm trying to have another stab at writing an LLVM ZPU backend. Any pointers or encouragement would be greatly appreciated. So far I've been wandering around the LLVM trying to read up and I've hacked together something that builds just to experiment and get a feel for the build system. I was able to write a backend for GCC which has been in use for years now, but I can't

Hi, I'm trying to find some written evidence to present to the powers that be that clang/llvm is ABI compatible with GCC 4.1 linux 64 bit. This would allow me to work with clang/llvm at my day-job and I would like nothing better! This is a pretty big app(millions of lines of code), so it would be interesting to see how llvm/clang behaves. Better warnings/errors and cutting down on build
