Hi Vesa, The pass IndVars changes the induction variables to allow SCEV to analyze them and enable other optimizations. This is the canonicalization phase. Later on, LSR lowers the canonicalized induction variables to induction variables that map nicely to the target's addressing modes. In many cases it can remove some of the induction variables. I suspect that the loop vectorizer does

Hi all, Sorry if this is a dumb or FAQ or the wrong list! I'm currently investigating LLVM vectorization of my generated code. My codegen emits a lot of recursions that step through arrays via pointers. The recursions are nicely optimized into loops, but the loop vectorization can't seem to work on them because of phi nodes that point to gep nodes. Some simple IR to demonstrate; it

Hi Nadav and Hal and thanks for the help! To the best of my understanding, indvars doesn't complain and an induction variable is detected. However, the loop vectorizer says: LV: Checking a loop in "add_vector" LV: Found a loop: Loop LV: Found an induction variable. LV: Found an unidentified PHI. %a.ptr = phi float* [ %a, %Top ], [ %a.next, %Loop ] LV: Can't vectorize the

I'd gladly install Linux on them, not windows 7. :-) Cheers, Renato On 9 Nov 2013 03:34, "Nathan Ridge" <zeratul976 at hotmail.com> wrote: > >> So, by dropping support for VS 2010, you will be making any developer > >> who uses Windows XP - potentially a large number of developers given > >> Windows XP's still huge market share - unable to build

We could create some special bonware that installs 7 on any XP machine it encounters. Volunteers? Tim.

Dear LLVMers, I’m investigating the response time of my JIT, and according to profiling, optimization takes 85% of the compile time, while the rest is being split evenly between the front-end and machine code generation. Much of the optimizer time is spent in various alias analysis passes. I’m happy with the generated code quality and wouldn’t like to lower the optimization level (O2). Would

Hello, there is a patch which allows redirecting UNIX domain sockets here: http://www.25thandclement.com/~william/projects/streamlocal.html<http://www.25thandclement.com/%7Ewilliam/projects/streamlocal.html> We really need it in our institution. It's for OpenSSH 4.4 but I managed to adopt it for 4.7p1 included in Ubuntu 8.04.

No, not just you. tw_cli is needlessly confusing

Hi, few months ago I started a thread about running PWGL under wine. PWGL is a " free cross-platform visual language based on Common Lisp, CLOS and OpenGL, specialized in computer aided composition and sound synthesis. " http://www2.siba.fi/PWGL/index.html However, because I had to use winetricks to install Microsoft Visual C++ 2005 (it's needed by PWGL), and the many errors that I

Freshmeat says: Following up to yesterday's Linux 2.0.38 release, Alan Cox sent out a security notice about a remote network DoS vulnerability which is present in all Linux 2.0.x systems. Linux 2.2.x is not affected by this bug. Causing this requires a great deal of skill and probably a reasonably local network access as it is extremely timing dependant. Nevertheless everyone is advised to

Dear Group, At http://biostat.mc.vanderbilt.edu/tmp/summary.pdf I have put a draft of a roadmap for choosing a method for analyzing serial (longitudinal) data. If anyone has feedback about this, including adding criteria for judging methods that I may have missed, I would appreciate hearing from you.
