Hi Chris, Does that mean that LLVM will be used in the Apple iPhone? >>> Eric On Jan 17, 2007, at 2:11 AM, Chris Lattner wrote: > > I'm happy to announce that Apple is contributing some major > extensions to the LLVM ARM backend.

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, 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

Hello, I would like to ask the llvm developers to have a look at http:// llvm.org/bugs/show_bug.cgi?id=918 . This bug has been reported 4 month ago but is none the less a somewhat serious one. Below I have pasted the test case and output of the issue running on my ppc machine. thank you Eric pb:~ eric$ cat testme.ll;llvm-as -f testme.ll;llc -march=c -f testme.bc;gcc -c testme.cbe.c

hello everyone, I few days ago I had some code (for the PyPy project) that llc - march=c converted to a switch statement and gcc compiled that nicely to a jumptable in the .s file. Now I try to reproduce when directly going from a .ll to a .s file. But I now see a long list of compare and jumps instead of the jumptable. Is there a transformation that does this if->switch(ing) or is

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

Hi Lauro, Just a stylistic remark; In your "llvm.patch" file, there are tabs in these lines: + if (GV->hasExternalWeakLinkage()) { + ExtWeakSymbols.insert(GV); + } Others will need to review the patch for correctness, though. -bw On 12/20/06, Lauro Ramos Venancio <lauro.venancio at gmail.com> wrote: > Adds external weak symbols of constant pool to ExtWeakSymbols set.

Hi Arvind, To use llvm inside scratchbox you must use a newer qemu. See http://setanta.wordpress.com/2007/11/20/qemu-arm-eabi-no-scratchbox/ (in Portuguese, but the important things are in bash :) ) I don't know if it is the problem in this case, but it should be the first attempt.

Hi, I must say I also was in need of this document but never knew it existed. It seems to be linked from the faq page only. I only read that the first day I came to LLVM. Maybe linking it from the GetElementPtr instruction in LangRef.html would make sense. cheers Eric On Nov 12, 2006, at 8:47 PM, Reid Spencer wrote: > Ram, > > Please read and understand the GetElementPtr FAQ

Rafael, Remember that the qemu <= 0.9.0 can misexecute code compiled by LLVM. I think you should test using qemu CVS.

Hi Mikael, You are obtaining warning, not an error, right? The most arm cores, including arm1136, can execute mul with rd = rm. So, you can ignore this warning.

Hi Everyone, I'm happy to say that LLVM has made many leaps and bounds since the last update in November. Because we are bumping the major version number with this release, we're letting the release go for twice as long as our planned release schedule (6 months instead of 3). We are currently half way through the LLVM 2.0 development cycle. So far, many important and invasive changes
