Not yet. Please see Bob's proposal:

Dear Najem, You might want to read the llvm-prof documentation if you haven't already: http://llvm.org/cmds/llvm-prof.html. The documentation mentions a script in the utils directory that automates some of the profiling tasks for you. I suspect the way that llvm-prof works is to compile your whole program to a single LLVM bitcode file, run a transform on it, and then generate native

Hello, I'm trying to evaluate the different register allocation algorithms on LLVM using the same level of optimizations. Using version 3.3 the current register allocators available to use are "basic, fast, greedy and pbqp". However, I'm facing the following issues: 1) I can't run basic and PBQP allocators using the command line flags of the dragonegg

Hello, I'm trying to evaluate the performance improvement of instruction scheduling on one of the inorder ARM processor, I was looking for ARM simulator and I found two (Simplescalar/ARM and SimIt-ARM) The code generated using llvm-2.9 and llvm-gcc and gcc 3.2. I used these command : $ llvm-gcc -O3 -o test1.bc -c --emit-llvm test1.c $ llc -O3 -o test1.s -march=arm test1.bc -mcpu=strongarm110

Hello, I'm trying to cross compile the MiBench benchmarks using LLC and ARM cross compiler the binaries generated will be used on pandaboard or the qemu-arm emulator. I have faced multiple issues during the compilation process, here are the commands used. # generate LLVM-IR for dijkstra_large.c $gcc -S -flto -o dijkstra_large.bc -fplugin=${DRAGONEGG} dijkstra_large.c # generate TARGET

Greetings All, We've been working hard on new codec negotiation stuff for Asterisk 18 and we've got some stuff to run by you. It's a lot so please read carefully. To give you some idea of just how difficult a job this is, a simple call from Alice to Bob currently causes 8 attempts to reconcile codecs between them in app_dial, chan_pjsip, res_pjsip_session and res_pjsip_sdp_rtp.

Hi, I''m doing one module in my site, there I need to import user blog into my site. I can use RSS feeds to read the blog information but using RSS feeds I''m not getting entire information. So, I need to scrape the user blog page. How to scrape a pages without knowing its html structure of a page? Please anyone can help me for this issue. Thanks in advance. -- You received this

Hi, Is there a way for me to collect statistics about the number of loads/stores added by the "linearscan" register allocator (just like can be done with the "local" allocator)? I still haven't grokked very well the interaction between RALinScan and Spiller... Should I add those two statistics to the spiller's class? Thanks, -- Silvio Ricardo Cordeiro --------------

Hi All We want to install packages like xfig and transfig on centos 5.5. We found rpms available but them but it seems there are lot of dependencies for these packages. So we would like to setup yum repo for this. Can anyone suggest trusted baseurl for yum repo? Regards Hersh -------------- next part -------------- An HTML attachment was scrubbed... URL:

I'm not sure about one thing: you assign stack slot to each new register you replace the spilled one with. And then you need to allocate physical registers to them. Is it possible to assign physical register to the virtual one which has a stack slot already?

Hi guys, I have been using a debugger for my register allocator. The debugger happened to be very useful at catching register assignment errors. I've put the debugger on-line, if anyone who is working with register allocation wants to use. The debugger itself has nothing to do with LLVM, but I've coded a spiller that prints the code in a format that the debugger can read. The

Can someone explain the theory behind the spillers in VirtRegMap.cpp? It seems as though the spillers do triple duty: - Insert load/store operations and/or fold instructions as necessary to carry out spills - Rewrite the spilled virtual registers to use machine registers (mapping given by the caller in the VRM). - Rewrite machine code to change virtual registers to physical registers

That is why they also have their weights set to #INF. Yes, that's true. But I wonder if we shouldn't be smarter about which register we pick to color it.
