You can see exactly what it contains by reviewing the "utils/llvmdo" script. The script is invoked by "utils/countloc.sh" with the -code-only option to eliminate a few things that shouldn't be considered code. The details are too long to list here but its simple enough to understand in the llvmdo script. To answer your specific questions, it includes makefiles and the

Reed, Are you working on a grammar of the LLVM syntax or also on a full semantics? Steve Zdancewic's group at U. Penn. is working on a formal operational semantics for LLVM. It is partially complete and Greg Morrisett at Harvard is planning to build further on it.

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,

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

Hi I was interested to see how Mongrel uses Lex/Yacc to parse the HTTP requests using a Regal generated parser. I downloaded the source but do not see the lex and yacc files...

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

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

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.

Hello everybody, I'm developing a source code transformation system for real-time systems currently, i.e. I want to map the application (a set of event handlers) to a run-time or operating system semi-automatically (if anybody is interested in the background - see below, of course, comments are welcome there, too ;-)). Therefore, I have to be able to express dependencies between different

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?

The gcc front-end page in llvm.cs.uiuc.edu seems to be down for the last 18 hrs. I was finding that tool very useful to get the syntactic constructs, could someone fix it ?

In this case, inliner is educated to add all local variables to the tag of enclosing parallel region, if there is enclosing parallel region. In our icc implementation, it is even simple, as we have routine level symbol table, the inliner adds ”private” attribute to those local variables w/o checking enclosing scope, the parallelizer does check and use it.
