similar to: [LLVMdev] doubt regarding gvnpre

Hello, I am doing a course project of "Adding the strength reduction in existing GVNPRE implementation". I know GVNPRE is not maintained and has been removed from trunk. But still can I get a single sample program for which it works correctly? Because for all the programs which I have tried it does not perform PRE.One such program is attached with this mail. It is important for my

It seems the GVNPRE pass has been removed from the main trunk, though it is present in the 2.6 release. From the llvm-commits archive, I found that it was removed  with this checkin: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20090928/088214.html "remove the GVNPRE pass. It has been subsumed by the GVN pass." Does the GVN pass optimize all the partial redundancies

Hi, I have a program as: int main(int argc, char **argv) { int a,b,k,l; scanf("%d%d",&a,&b); if (argc > 1) { k=a+b; } else { k=5; } l=a+b; printf("%d,%d",k,l); return 0; } Now i run the following on it: llvm-gcc -O1 -emit-llvm -c -o 1.bc 1.c llvm-dis 1.bc -o 1.ll opt

Hi Daniel, Got it. If that's the case, can I implement it under the guidance of your insights/prototype? I think I can spend more time on implementation.

Hi Daniel, Thank you for your detailed reply, and thank you for working on GVNPRE. I’d more than happy to test/evaluate it with our benchmark once it is ready. Please let me know if you need any help.

Dear all!! I am using R1.4.1 on windows 98. I had been trying to organize the package and has already been able to document some of the functions in to .Rd (R documentation) files. From these .Rd files I generated plain text files as well as html files. I have also given the 00Index file in each of the directories: html/ help/ data/ man/ Problem: I don't get the help using comand

Hi, I am trying to setup Xen to use "PV on HVM". For this, I did the following. (1) I followed the tutorial at http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial to setup Xen4.0.1 on Fedora13. I am able to run virt-manager and create a Fedora 13 guest. (2) I followed the tutorial at http://bderzhavets.wordpress.com/2010/05/27/pv-on-hvm-at-xen-4-0-on-top-of-fedora-13/to use PV on

Hi All, The PRE or GVNPRE is not effective for the below use case. int sum; int phi =30; void f (int i, int *a) { if ((a[i] << (1)) > -15) sum =(phi+ 0x7fffffffL )/ a[i]; if ((a[i] << (2)) > -15) sum =(phi + 0x7fffffffL) /a[i]; } respective asm (clang on trunk ) #clang -O3 -S test.c BB#0: # %entry pushl %edi pushl %esi

Daniel Berlin knows > much about GVNPRE, so he could probably comment more on it. I implemented GVN-PRE for GCC. You could probably do an implementation for LLVM in three months,

Hello, In some of our internal benchmarks, I observe that LLVM performs worse than GCC because LLVM fails to perform PRE when GCC can. I hope this problem goes away when NewGVN equipped with PRE, and wonder if anyone has an idea about the status of PRE on top of NewGVN. Thanks!

I have written a simple pass. I have been successful to execute it. I want LLVM to execute it. I don't know how to include a pass in llvm actual pass list, such it automatically invokes it just like GVNPre pass or some other pass. They have already been limked in llvm actual pass list. -- regards, soumya prasad ukil -------------- next part -------------- An HTML attachment was scrubbed...
