It is my understanding that the implementation for jump-threading in LLVM is not presently able to effectively optimize code containing a state-machine implemented using a loop + switch. This is the case, for example, with the Coremark benchmark function core_state_transition(). Bug 42313 was filed to address this in 2019: https://bugs.llvm.org/show_bug.cgi?id=42313 It appears that GCC

This is off-topic. I''m hoping someone on this list can point me towards more general information on finite state machines, their definition, how to build them, determining when to apply them, etc. I read Zed''s blog entry from way back when covering Ragel [1] but he hasn''t followed it up and there aren''t many pointers to external information.

Hi. Does anyone know whether CA(Cellular Automata), GA(Genetic Algorithm) or Multi-Agent System is available for R for Win? I've already knowna software for these areas, SWARM or startlogo. But I'd like to link R's function with these methods. -------------- next part -------------- An HTML attachment was scrubbed... URL: https://s...

...in to have spacial autocorrelation. And after, what is the number of individuals responsible for this autocorrelation. The main idea is to discover if exist a contamination of a quadrat from others quadrats and how is the population needed to make this contamination. This is very common to use automata to simulate this situation. But I try to make a more statistical approach. I'm studing about, but I dont know the tool for testing examples. I make an example just for tests: Geodata <- data.frame(X=rep(rep(c(1:10), (rep(10,10))),5),Y=rep(c(1:10),50),Abund=c(1, 0, 0, 0, 0, 0, 0, 0, 0, 1,...

...nd I have also tried png() instead of bitmap(). (I do prefer bitmap so this can run without x11.) I am guessing that R's internal region calculations are vector based, which generally makes sense for most statistical plots. However, I do have some ideas for R and the presentation of cellular automata results. Any tips out there? (Is it just a matter of height=50px to overcome the inches default, etc?).....

...ntation", "Dynamic Snippets", "Gmane Search improvements" or even "Replace socket code with ZeroMQ" project (I have an experience of developing distributed systems using HornetQ messaging system). Additionally, currently I'm doing some research on Levenshtein automata and it shows competitive results, so I can implement it as one of spelling correction algorithms as a bonus. As you know, I'm familiar enough with Xapian code base and have good skills so you could offer me any other project if you think it has higher priority. I suggest we discuss it on the...

...a dynamically typed FPL based on term rewriting: http://pure-lang.googlecode.com/ It uses the LLVM JIT to compile and execute code on the fly in an interpreter-like environment, and can also batch-compile code to native executables. This includes the deterministic (non-backtracking) tree matching automata needed to implement general term rewriting in an efficient manner. > How good is LLVM for this? There haven't been any other implementations of Pure compilers so that I can't give you a real comparison. What I can say with confidence is that LLVM made developing a code generator for Pu...

Hi, are there any attempts to use LLVM in graph-rewriting (term-rewriting) language implementations? How good is LLVM for this? E.g., is it natural to expect that the LLVM-based implementation of the language Concurrent Clean be any faster than its reference implementation?

Hello! is it possible to boot a 32 Bit Kernel on 64 EFI firmware with Syslinux? I copied "efi64/efi/syslinux.efi", all files inside "efi64/com32/modules" and the file "ldlinux.e64" to my boot partition. with this configuration I am able to boot a 64 bit kernel. but not 32bit Kernel. does anyone knows how to do it? Best Regards

Hi all, I'm organizing a BoF session during the upcoming EuroLLVM developers meeting. As the subject of this message already shows, this session will be on compilers in education. I'm currently looking for both participants to the discussion and input for the actual program of the session. I've already got some ideas which I'll introduce below. At our university, we mostly

...ile timeouts at DHCP-time in ipconfig when starting up several machines (say: 2 out of 4 don't boot) at the very same time (FWIW, using the 'reboot' mechanism of our SSI system, which means the reboots happen in sync). Finally, I found some time to look into it, and discovered that the automata doesn't take some cases into account. First, I've rebuilt ipconfig with DEBUG/IPC_DEBUG, and discovered that the machines that don't boot receive the messages broadcasted by the other dhcp clients (be it DISCOVER or REQUEST) and from that point on, receive nothing else. Now, looking at...
