Hi everyone, I've just checked in an IA64 backend to LLVM! Be warned, it's pretty rough right now. Here are some of the known defects: - No varargs - No alloca - No instruction scheduling/bundling of any sort ...or in other words, it breaks often and when it does work, it's a dog. On the plus side, it _does_ have a tasty new pattern instruction selector. :) Beyond fixing the

The two bugs I mentioned (no varargs, no alloca) are pretty much two sides of the same coin: I'm ignoring the IA64 stack frame layout (for no good reason), so

However, GCC 4.x definitely has issues building LLVM, at least on ia64. If you want to use LLVM in anger, I'd stick with 3.4 for now.

You are right, the machine I am on is a AMD Opteron. I could probably generate working code for x86, but I am testing the implications of using 64 bits integers. The four weeks is not really important, it's just that it would be nice to have really fast code to showcase. Something related to this: to test the effect of 64 bits integers I replace all reference of int by long in my .ll file.

Hi all, This is just to announce that I have a FreeBSD x86 machine running the test suite more or less continuously: http://kinoko.c.u-tokyo.ac.jp/~builddonkey/ Of note is that it now runs Dejagnu tests. (Thanks, tonic+co!) I'm also tracking CVS breakage (internally, for now). At some later point, I'll make available more real-time information on "is CVS alive and if not,

Hi, everybody: I am a beginner with LLVM, in fact today was the first day that I use it. I have several questions about LLVM: Can I use LLVM to compile several files (bytecode), scripts (char*) and link them with external libraries generating *only* one executable (all in memory)? Can I invoke externals functions from a guest (LLVM generated) code which exist in the host code (the code that

Hi there, The IA64 architecture, which had its 'official' name changed to the "Itanium Processor Architecture", *is* supported by llc. I am pretty sure you are talking about the x86-64 architecture, which has also had its share of unfortunate name changes and is also known as "AMD64", "EM64T" and all sorts of things in between. x86-64 is *not* currently

I have used Perforce also and fully agree it's wonderful. The only concern I have is with their license for open source projects. The only gotcha is that it must be renewed annually, and they reserve the right to not renew it (though they say they won't unreasonably deny renewals). Not sure how much this really matters, as Perforce strikes me as being one of those "do no

Hi, For the PyPy project ( http://codespeak.net/pypy ) I am working on the x64-64 support. I would like to use llc -march=ia64 to generate the assembly but that is not supported at the moment. As a workaround I let llc generate C code that gets compiled, but this unfortunately is not a good way to show the power of llvm. A understood this ia64 support will be worked on soon. First week of july

Hi Vasanth, Can you be a little more precise about what you mean by "dynamic optimization"? In one sense, neither LLVM nor Pin are dynamic optimization tools per se - LLVM is more of a compiler(-building) suite while Pin is an instrumentation toolkit. > 1.

Hi Everyone, Sorry for the long overdue status update, as you might guess, the holidays have been busy for everyone. :) Here's your periodic dose of updates on the progress of LLVM, which takes us from the LLVM 1.4 release until present CVS. I appologize if I forgot anything! Big Things: 1. Brian contributed a new SparcV8 backend, which (unlike the SparcV9 backend) uses the

Hi all, First time poster and a relatively new R user, I'm beginning analysis for my masters degree. I'm doing a bit of work on octopus behaviour, and while it's been fascinating, the stats behind it are a bit beyond my grasp at the moment. I was hoping that somebody with more experience my be able to look at my example and offer their wisdom, much to my appreciation :-) At the most
