similar to: [LLVMdev] Tooling support for LLVM-GCC, or CLANG?

I'm more interested in whether or not there are any projects in the works that fuse the tools together to build a better IDE experience. I forget which presentation it was, but one of the developers (I *think* it was the gentleman that presented something on CLANG at the dev's conference 2008) made a bit of a point by saying that LLVM, unlike GCC has been built from the ground up with

I'm not so sure that is a very good reason, depending on your implementation data structures that are fundamental to the type system of the virtual machine use custom allocators so the extra hop carries little to no expense. I would not have considered it had I

True. Perhaps that is a good argument for providing both kinds. However, nulls are certainly more

That sounds like a problem. Just so I understand, do you mean there isn't the run-time support etc. to write back ends for the C++ language, or that the compiler IR is also somehow insufficient to write a code generator? --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Jul 11, 2009, at 3:00 PM, Granville Barnett

When you create a parser via ANTLR you specify the output language of the resulting recursive descent parser, at the moment there exists no C++ output template to my knowledge, thus you would have to generate the parser as C code for which a template exists. The runtime support should be there, at least partially but it won't use things like exceptions, nor will it have a very modular design

Are there any papers in the works which benchmark some specification suite of C programs on GCC, LLVM-GCC, and CLANG? The only stuff I have seen so far are some bar charts in a few LLVM presentations, would be nice to have something a little more comprehensive.

Hi, I've not got any experience using ANTLR to parse C++, however, you will find that there only exists a C code generator for ANTLR and NOT a C++ one. Over the years numerous people have requested a C++ code generation template but alas there is still only a C one. Just a heads up. Granville 2009/7/11 Vikram S.

We are looking for an open source C++ parser other than g++ if possible. Clang would be great but its C++ support is still some way away and we need something that works or nearly works now. Does anyone have any experience with ANTLR for parsing C++ and for extending their C++ parser? Any other feedback on ANTLR in general would be welcome too. Thanks, --Vikram Associate Professor,

Trying to capture a notion of overall compiler optimization in a representative set of benchmarks is a hard problem. If you're interested in performance, it's best to measure it on the applications you're interested in. You should be suspicious of any one-dimensional analysis of compiler optimization, especially if it's presented by someone with an interest in a particular

A while back there was a discussion thread about whether an accurate, concurrent garbage collector could be "generic" in the sense of being able to support multiple different languages efficiently. After having done some work on this, I now believe that this is the case - using C++ policy-based design principles, you can create a set of modules that represent different aspects of

Does anyone know if load balancing and DNAT work well together? I know that load balancing and NAT do not, but what about a simple port forward? I can''t apply Julian Anastasov''s patches, because they don''t work with PPTP patches. :/ Anyhow, a simple: iptables -t nat -A PREROUTING -i eth0 -p tcp --dport xxx -j DNAT --to yyy:xxx iptables -I FORWARD -i eth0 -d yyy -p

I have some data consisting of multiple trials of an experiment with different values of an independent variable. If I run R> plot(var,result) I get a scatterplot of result versus the independent variable var.

That used to be the case, but not so anymore. Intel compilers generate just fine code for AMD

Hello. I'm using these commands to compile the code below in order to collect edge/blocks profiling: clang -emit-llvm -c sort.c -o sort.bc opt -insert-edge-profiling sort.bc -o sort_prof.bc clang sort_prof.bc -lprofile_rt -L/llvms/lib -o sort_prof then I run the program and display the profiling information using llvm-prof sort_prof.bc, and the result is:
