I posted this question on the llvm channel on irc. I am new to all of this. And I only found out about LLVA as a result of the irc. And please forgive my erroneous terminology. So let me try this as best I can. I want to know if the code of LLVA/LLVM can be used as a virtual processor in configuring the linux kernel? Maybe you have already encountered this and possibly accomplished it as

Hi, I ran into a problem when running DSA on Linux kernel (the Kernel version I used is 2.4.31). The analysis was aborted when it tried to do DSNode::mergeTypeInfo on some data structure in the kernel. I have filed a bug report at http://llvm.org/bugs/show_bug.cgi?id=1656. My question is what version of Linux kernel LLVM has been tested on successfully? To run DSA analysis, should I use the

Is the source code for llva available esp the linux kernel port. Is there a project page for llva ?

I don't know the current status of the LLVA project, so I will let the current developers chime in.

The llva-emu code is extremely old and, as I recall, not very feature-filled. It was also done for a class project (I don't think it was used for the original LLVA publication, and it wasn't used for any of the subsequent LLVA/SVA publications

Hi All, can anyone tell me where I can find the sources for the llva-emu project? I've tried to contact  Michael Brukman or Brian Gaeke but no reply. thank you for any help, dacian -------------- next part -------------- An HTML attachment was scrubbed...

There is a strange Writable Instruction Set Computing CPU from Imsys (Sweden) based on FPGA. Is it possible to setup the IMSYS CPU for running applications based on LLVA/LLVM? Thank you. Swedish microprocessor developer Imsys Technologies has released three devices in its reconfigurable family of processors. Unveiled at the Microprocessor Forum in San Jose, each device combines the processor with

Hi, I have been away from the list for a while, so do apologize in advance if the topic is slightly off topic here. I have started a hobby project to create a virtual OS library (jos). The idea was to create a set of C API's for operating system specific tasks i.e. File IO, threading and etc. For example: typedef jos_handle jos_thread; jos_thread jos_thread_create(...); void

I'm interested in understanding the extent of the assumptions which llvm makes about the types of hardware it is capable of targeting. In particular, I'm investigating a proposal by Zack Rusin to use llvm as the shader compilation engine within Mesa, targeting GPU backends. I'm aware of the Apple GLSL compiler, and also I've seen the Vector LLVA paper. However, I'm not

Different pieces of the compiler make different assumptions. In particular, the code generator we ship is good for targetting certain classes of devices, but isn't fully general (it doesn't help

Hi, How to correlate the LLVM IR-leve instructions and memory values with the machine instructions and memory locations? For example, if CMP instruction in machine ISA is selected for the ICMP instruction in LLVA, with the Instruction datastructure for ICMP, is it possible to get the memory address of CMP instruction? Assume that the code segment base address is given. Similarly, by

Can you tell us what goal you are trying to accomplish that requires you to do this? There might be better ways of doing what you want. The answer to your question probably depends on whether you're trying to write a
