Hello, if I compile with dragonegg and -march=native I get this message: 'bdver1' is not a recognized processor for this target (ignoring processor) Is there any plan to support this cpu ? Here the full example the source file doesn't matter. gcc -s -static -Wall -O2 -march=native -fplugin=dragonegg.so -fplugin-arg-dragonegg-enable-gcc-optzns pointer.c -o pointer

For a while now we (Cray) have had some very primitive cache structure information encoded into our version of LLVM. Given the more complex memory structures introduced by Bulldozer and various accelerators, it's time to do this Right (tm). So I'm looking for some feedback on a proposed design. The goal of this work is to provide Passes with useful information such as cache sizes, resource sharing arrangements, etc. so that they may do transformations to improve memo...

Dear Andrew and the Group, I’m trying come up with a SchedMachineModel for the AMD bulldozer http://en.wikipedia.org/wiki/Bulldozer_(microarchitecture). The model is not exist for the same .Please correct me if am i wrong here. I was going through your reference @ https://llvm.org/svn/llvm-project/llvm/trunk/include/llvm/Target/TargetSchedule.td . But I couldn’t model some of t...

Dear All, Attached files is related to the changes made to add the Schedmodel for a AMD bulldozer target, Please note that , the model is incomplete but has some of the valuables features implemented. Request to the group or someone from AMD for the comments on the implementation. Thanks ~umesh On Wed, Nov 13, 2013 at 8:14 PM, Umesh Kalappa <umesh.kalappa0 at gmail.com>wrote: >...

If you haven't found it yet, the last public AMD Software Optimization Guide for Family 15h is here: http://developer.amd.com/wordpress/media/2012/03/47414_15h_sw_opt_guide.pdf This one describes both Bulldozer and Piledriver processors. Chapter 2 will given an overview of the Microarchitecture and Appendix B gives some additional details on which pipes are used for where. I haven't yet looked in detail at your patch to check your model, but at minimum the comments, references and naming still all r...

...mail has the old patch file. Please have look at the attached patch file herewith,which has the latest changes. i'm new to llvm testing framework and cross compilation as such ,Please can you through some lights like references etc ,Which states that how can i cross compile the llvm for Bulldozer and run the performance test against my changes.So that i can tune for a better result.

...ething if I delete agp from conf file in both cases? Another issue bothers me also. RC version of amdtemp failed to read temperatures on 8120. What version will be included in release? Some months ago there was a post of people taking source from current and compiling mo- dule. It worked on 8 core bulldozer. Best regards all Zoran
