similar to: [LLVMdev] benchmark suitable for testing the jit

hi everyone, I am planning on creating a local SAN via NFS(v4) and several redundant nodes. I have been using DRBD on linux before and now am asking whether some of you have experience on on-demand network filesystem mirrors. I have yet little Solaris sysadmin know how, but i am interesting whether there is an on-demand support for sending snapshots. I.e. not via a cron job, but via a

hi all, i would like to ask some questions regarding best practices for zfs recovery if disk errors occur. currently i have zfs boot (nv62) and the following setup: 2 si3224 controllers (each 4 sata disks) 8 sata disks, same size, same type i have two pools: a) rootpool b) datapool the rootpool is a mirrored pool, where every disk has a slice (the s0, which is 5 % of the whole disk) and this

Hi, I'm trying to run the benchmark suite: http://llvm.org/docs/TestingGuide.html#test-suite-quickstart I'm doing it the lnt way, as described at: http://llvm.org/docs/lnt/quickstart.html I don't know what to expect but the results seems to be quite noisy and unstable. E.g I've done two runs on two different commits that only differ by a space in CODE_OWNERS.txt on my 12

Hi all, I was trying to compile dfsan with wget. (Just enabling the dfsan feature, without actually making changes to the source code) Without dfsan, I am able to compile and run wget 1.19.5 (available at https://ftp.gnu.org/gnu/wget/wget-1.19.5.tar.gz). But when compiled with dfsan, it encountered a null pointer dereference error. Following an old post:

Hi, I need to be able to use a special case list file containing thousands of entries (namely, a list of libc symbols, to be used when using DFSan with an uninstrumented libc). Initially I built the symbol list like this: fun:sym1=uninstrumented fun:sym2=uninstrumented fun:sym3=uninstrumented ... fun:sym6000=uninstrumented What I found was that, despite various bits of documentation [1,2], the

hi all, i surely overlooked something. but i am currently trying to do some benchmarking stuff with llvm. in my thesis i was using llvm-1.5 (i did some extension work, which i would have to frontport now). But unfortunately 1.5 is for some benchmarks unstable (at least on my box) such that llc sigsegvs sometimes, etc. So I wanted to give 1.9 a go and build that on the my intel mac book. I did

Two other things: 1) I get massively more stable execution times on 16.04 than on 14.04 on both x86 and ARM because 16.04 does far fewer gratuitous moves from one core to another, even without explicit pinning. 2) turn off ASLR: "echo 0 > /proc/sys/kernel/randomize_va_space". As well as getting stable addresses for debugging repeatability, it also stabilizes execution time

I recently wrote an LLVM-based JIT plugin for libgcj and I thought it'd be worthwhile to mention it here. It is in cvs on sourceforge, but afaics anonymous cvs there is pretty broken at the moment... so if you want a copy, ask and I will email it to you. Basically I hacked libgcj to (optionally) dynamically load JIT module at startup. If a JIT is loaded then bytecode is passed to it rather

Hi Mike, hope you are doing well with the llvm gcjx backend. I am currently writing an llvm backend for a C like language for tracing (like D in dtrace). I am very interested in this area. Do you currently put your work in a repository? (maybe as Tom suggested gcjx.sf.net would be an easy start - since it would not require gcc committer status). I am keen on getting LLVM support for gcj. Maybe we

This is a interesting thread. I think this would also help with compiling scripting languages such as JavaScript/Python etc. We could keep the high level meta data and runtime binding info as language specific bytecode in the file and just have the parts that are easy to represent as compileable in the main object sections. There is no intrinsic reason for all the runtime type information to get

Hi, Except for the guide in http://llvm.org/docs/Projects.html#help, is there any easier way to get the llvm projects for famous benchmark suits, such as MiBench, SPEC2000, .etc? In other words, is there preconfigured and downloadable llvm projects for famous benchmark suits? -- Best regards, Li Qingan -------------- next part -------------- An HTML attachment was scrubbed...

Hello OvermindDL1, We are implementing an extensible language. That's one where you can add commands and constructs to the language without having to recompile the parser. We want compilation of the parser in order to "freeze" it but only as an option. One goal is to eventually get the macro functions of our language to the point where they are equivalent to the template
