similar to: [LLVMdev] is anyone using the sparc backend?

FYI, I completely agree that we shouldn't remove the sparc target. However, it is currently unmaintained, and has some pretty glaring bugs. Is anyone interested in stepping up to maintain the target? -Chris On Oct 25, 2011, at 6:35 AM, Vikram Adve wrote: > Sparc is a popular target for architecture simulators, and removing that back end would force people using such simulators to use

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,

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

First, kudos on the ThinLTO results reported in your blog post — they’re impressive and the system sounds really well engineered. I’m starting to try it out on a large piece of software and I’d like to make sure I know what to expect. The blog said it will be available in clang-3.9 but both clang-3.8 and trunk seem to have some degree of support for it. What is the status of ThinLTO in 3.8

Hal, Andrey, Alexey, >From the LLVM design viewpoint, there is a fundamental problem with both Hal's approach and the Intel approach: both are quite language-specific. OpenMP is a particular parallel language, with particular constructs (e.g., parallel regions) and semantics. LLVM is a language-neutral IR and infrastructure and OpenMP-specific concepts should not creep into it. I've

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

I've done extensive research on the subject and if you want to parse ALL of C++, there are only two options, g++ or the Edison Design Group C++ front-end. Both of these have projects designed to make this easier LLVM (as you know) and Rose (http://www.rosecompiler.org/), which works with the EDG compiler. AspectC++, OpenC++, Antler, TLX, all work with only a portion of the grammer. On Sat,

Unfortunately, the data in the paper doesn't show that, through no fault of the authors :-(. It might be nice to add a qualification and a pointer to this graph along with the paper, if John doesn't object. --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Nov 18, 2008, at 12:33 PM, Chris Lattner wrote: > >

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.

I'm trying to decide whether to use either the MIPS or ARM back ends for course projects in our introductory compiler class. I'd like to use something that has a stable back end, so that the students can use the selector, probably without changes, and do a project on register allocation and stack layout. We don't have MIPS or ARM hardware (other than possibly a few donated Android

Dear LLVM users, The development of LLVM has been supported primarily by funding from the National Science Foundation and the University of Illinois. in order to maintain our sources of funding and attract new ones, It is important for us to be able to document how LLVM is benefiting companies, universities, other organizations, and individuals in the outside world. (The information

Dear all, Is anyone aware of any implementation of an inter procedural slicing algorithm for LLVM? I am mostly interested in a static algorithm but a dynamic one can be helpful too.

I too am disappointed that not all talk slides are posted. To me it speaks poorly of the whole meeting since there were parallel sessions and not everyone could attend in person all the sessions they wanted to. The slides are, I thought, meant to be like the "proceedings" and If I recall some of the Apple slides are present from previous years but not this year. Vinod On Sat, Oct 17,

Dear Prof. Adve, I recently checked out the llvm using cvs update command under the llvm directory. But when I went to see the DSNode.h, there is no getPointerSize function. I checked the doxygen tree, it's there. So that means I didn't update my cvs tree correctly. Could you let me know how to update my CVS tree? Or there is a problem at somewhere else?

Hi Shuo, I am CCing your questions to the LLVM developers list so others can reply or correct me. >I have a few questions about LLVM: >(1) The LLVM tutorial says LLVM can be used in architecture research.

Hi Mehdi, Yes, we did see your earlier post. Efficient (de)serialization is definitely important for both exporting (a la LTO and ThinLTO) and for shipping code as IR. I expect most use cases of the latter would benefit. -—Vikram // Vikram S.
