Hello to all LLVM Developers. Given a object from a LiveInterval class, is there any way to know if this Live Interval is part or is inside a loop?

Thanks Matthias I can also use the method intervalIsInOneMBB() from LiveIntervals class to relate a LiveInterval to a MachineBasicBlock, right?

Good Afternoon. I am a Computer Science undergraduate student in Brazil and as completion of course work, I am developing an register allocator, using the infrastructure of the LLVM. To accomplish this task, I have based my implementation in allocators already implemented in LLVM. But a question came to me while I was researching in books and articles of compiler theory and own documentation of

I'm working on my project for completion undergraduate courses, consisting of an experimental analysis of registers allocation algorithms. For this task, I am using the set of tools from the LLVM project. However, I have read the documentation of the LLVM project and not yet found a way to put the pieces of the puzzle together. So far I know: - As passes work as engage them to LLVM and

Hello to all LLVM developers. I'm developing a register allocator using LLVM, my allocator has a local search phase: given a solution (assignment of virtual registers to physical registers or memory) generated in the first phase of the algorithm, some movements are applied to this solution in order to find a better solution. To apply such movements, I need to unassign a virtual register from

We have talked about whole function instruction selection but does not have immediate plan to implement it. If we were to implement it today, it would probably be done on DAGs with

Hi, LLVM already uses dynamic-programming based optimal pattern matching selectors for some of the target architectures. But as far as I know, the code is first converted out of the SSA form, before the selection process takes place. The same approach is used by many other compilers. But there is an article from Erik Eckstein, where a different method is proposed. In the described approach, the

Actually I am trying to run SPEC2006 through the Makefiles provided with LLVM Test Suite, so I think it should work properly...

Dear LLVMers, I am implementing a Function Pass and I would like to use analysis obtained from a Module Pass. Some extracts of my code look like that: struct MyPass : public FunctionPass { static char ID; MyPass() : FunctionPass(ID) { PADriver &PD = getAnalysis<AModulePass>(); ... virtual void getAnalysisUsage(AnalysisUsage &AU) const{

Dear LLVMers, I am having trouble to run SPEC2006. I have checked in my log file that the spec root has been correctly found with ./configure, but when I try: make TEST=simple in the External folder I get the following error: make -C /home/izabela/svn_llvm/llvm/projects/test-suite/tools all \ ORIGINAL_CC="clang" \ ORIGINAL_CXX="clang" make[1]: Entering directory

I can't really tell what is happening based on this output, but 'make' is not the right way to build SPECcpu2006 components. You need to do either by using the supplied 'runspec' command with '-build' action directive or to issue the 'specmake' (which is a make adjusted by spec.org) on the build component folder. I can build 433.milc on PPC64 with clang without

Hi Leslie, I suggest adding these 3 papers to your reading list.

Hi Jakob, Yes. I have references. For example, from the top of my head I would name the following papers: 1)  A Generalized Algorithm for Graph-Coloring Register Allocation by Michael D. Smith, Norman Ramsey and Glenn Holloway      http://www.cs.tufts.edu/~nr/pubs/gcra-abstract.html 2) Register allocation by puzzle solving by Fernando Magno Quintão Pereira, Jens Palsberg    

Ok, just to clarify, RegUnits, as far I understand, are Physical registers or alias to Physical registers. They exist because some instructions use physical registers directly rather than virtual register. It's right? And why this RegUnits should be present in the Interference Graph? I thought were only the Live Intervals would be the nodes of the graph. Sorry about the trouble to

I've installed libvirt and also Virtual Box OSE hypervisor, in order to see if I could properly manage it through virsh. I could easily set up, start, pause, resume, shutdown and destroy the newly created domains, from a XML file. Then I was wondering how could I be able to spawn commands in the domain through virsh, and the command 'console' gave me a the thought that I should
