Hi all, I think this master's thesis from our group could be of interest. It describes the "bridge" between the LLVM codegen and our custom TTA codegen in TCE: a runtime retargetable architecture description file driven LLVM compiler backend. The thesis might be useful also for people implementing backends for LLVM in general. http://tce.cs.tut.fi/doc/Compiler.pdf If you have any

Hello, Attached is a trivial patch to increase the max number of physical registers in LLVM from 1024 to 16384. In our TCE toolset we allow the designer to choose the number of registers in the designed TTA processors freely, and recently while experimenting with using TTA for a GPU design we have bumped into this limit several times. What has made matters a bit worse for us is that we need to

Hello LLVM people, Our customizable TTA target [1] is capable of having plenty of registers and register file ports to improve instruction level parallelism and reduce spills. It's totally up to the designer of the particular TTA processor how much the processor has registers and register file resources along with other TTA components. We have ported LLVM 2.1 to produce an intermediate TTA

Hi, I wrote an LLVM blog post about our use of LLVM in the TCE project and a bit of a background for the TCE project in general. I hope some of you will find it interesting :) http://blog.llvm.org/2010/06/tce-project-co-design-of-application.html -- Pekka

Hi there, i created a Function Pass to retrieve the Control/Data Flow Graph from a simple program, now i would like to statically schedule the Instructions. Is this possible by starting to modify the SelectionDAG Files ? Or can i even build a "standalone" custom scheduler? Thank you very much for any tipps. Ben

Hi, Would it be possible to set tbgen to be installed with llvm? For our project http://llvm.org/ProjectsWithLLVM/#tta-tce it would be very helpful, because our tools generate compiler backend plugins in the fly for each customized processor and plugin generation needs tbgen for handling td files. Because of tbgen not beeing distributed, our users cannot use llvm from their favorite

Hello gyus, I am working on a project, where we are trying to create a development environment for new ASIP processor design. Part of this project is a compiler generator, where we would like to generate C compiler from some instruction description. To keep it short, let's say, that in each instruction's semantics is described by some C code. What I would like to do is to compile this

Portable OpenCL (pocl) v0.6 released ------------------------------------ Portable OpenCL aims to be an efficient open source (MIT-licensed) implementation of the OpenCL 1.2 standard. In addition to producing an easily portable open source OpenCL implementation, another major goal of the project is improving performance portability of OpenCL programs with compiler optimizations, reducing the

Not to my knowledge. > Another solution (which we use in TCE) is to use register renaming. You do it in LLVM? Do you plan to upstream it? Also, I do not know your target/goal, but do you look at global scheduling at all? Thanks. Sergei -- Qualcomm Innovation

TTA-Based Codesign Environment (TCE) is a toolset for designing application-specific processors (ASP) based on the Transport Triggered Architecture (TTA). TTA is a minimalistic processor architecture template that allows high level of control for the designer to choose the boundary between the hardware and the software. The toolset provides a complete codesign flow from C programs down to

TTA-based Co-design Environment (TCE) is a toolset for design and programming of low power customized processors based on the Transport Triggered Architecture (TTA). The toolset provides a complete retargetable co-design flow from high-level language programs down to synthesizable processor RTL (VHDL and Verilog generation supported) and parallel program binaries.
