I'm trying to run the example described at: http://llvm.org/docs/DebuggingJITedCode.html I followed the sample command line session (below, with versions numbers for everything), but gdb doesn't stop at the breakpoints as described. Any idea what is wrong? Thanks, Zach zdevito at derp:~/terra/tests$ > ~/clang+llvm-3.4-x86_64-unknown-ubuntu12.04/bin/clang -cc1 -O0 -g >

Nadav, We see multiple regressions after r172868 in ISPC compiler (based on LLVM optimizer). The regressions are due to spill/reloads, which are due to increase register pressure. This matches Zach's analysis. We've filed bug 17285 for this problem. Is there any possibility to avoid splitting in case of multiple loads going together? Dmitry.

Hi, there! I?m Suzana Joel from Lumos Labs. I?d like to invite you to attend the Think with Terra Tech Talk - Back to Blockchain Basics, that?s scheduled to take place on *Monday, 5 October at 5:30 p.m. IST. * The Tech Talk will feature three sessions to help anyone get a working understanding of - - blockchain technology, - Smart Contracts, - Building on the Terra

I've narrowed this down to a single kernel (kernel.ll), which does a fixed-size matrix-matrix multiply: # ~/llvm-32-final/bin/llc kernel.ll -o kernel32.s # ~/llvm-33-final/bin/llc kernel.ll -o kernel33.s # ~/llvm-32-final/bin/clang++ harness.cpp kernel32.s -o harness32 # ~/llvm-32-final/bin/clang++ harness.cpp kernel33.s -o harness33 # time ./harness32 real 0m0.584s user 0m0.581s sys 0m0.001s

Hi, I wanted to propose another project that is based on LLVM for inclusion on the http://llvm.org/ProjectsWithLLVM/ page. Hope it qualifies and can be included. Below description is copied verbatim from their website. I formatted it to follow the format of entries on aforementioned page: > RetDec > > by Avast > > RetDec is an open-source machine-code decompiler based on LLVM.

Thanks for all the the info! I'm still in the process of narrowing down the performance difference in my code. I'm no longer convinced its related to only the unaligned loads/stores alone since extracting this part of the kernel makes the performance difference disappear. I will try to narrow down what is going on and if it seems related LLVM, I will post an example. Thanks again, Zach

Thanks for the report. The attached patch removes them from the page. OK?

I have been working with Antti Kantee on running scripting languages directly on Xen, and have got LuaJIT running. Essentially this is a build of a modified version of the Xen "Mini-os" which provides a small stub to handle basic Xen functions like memory allocation, combined with NetBSD kernel components to provide networking and file system access if required, plus NetBSD libc to

Not sure, but it seems the page contains a number of out-of-date entries: Pypy => pypy.org (link stale) plus: there is no llvm backend for pypy at the moment (although LLVM backends have been attempted a number of times, all seem to have failed) Unladen Swallow => not being developed since 2011 (http://qinsb.blogspot.com/2011/03/unladen-swallow-retrospective.html) TIA, Andreas The

Hi, Yes. On Sandybridge 256-bit loads/stores are double pumped. This means that they go in one after the other in two cycles. On Haswell the memory ports are wide enough to allow a 256bit memory operation in one cycle. So, on Sandybridge we split unaligned memory operations into two 128bit parts to allow them to execute in two separate ports. This is also what GCC and ICC do. It is very

Hi, Can anybody show me how to extract all columns in my dataset that are polymorphic? Or phrased in another way I would like to delete all columns that have no more than one letter in it (that are monomorphic). Thank you.

Hi, What other information should i post? I now have the two versions on the same machine. With R 2.3.1 and tseries 0.10-7 it works fine. With R 2.6.0 and tseries 0.10-11 the function garch doesnt work. The test was made with the same data, in the same machine. The maintainer did not say anything yet. Regards, Jos?

Hi there, I am having some trouble implementing a quota proxy server for a memcached based dict (I am using the version 2.2.15). I created a multi-threaded daemon that is using non-blocking sockets to receive the data and reply to dovecot. Right now everything but the atomic increase message is working great. Here is an example of such a message: B1 A1??? priv/quota/storage??? 86583 A1???
