Hi, While crosscompiling the kernel for openrisc with allmodconfig the build failed with the error: drivers/vhost/vhost.c: In function 'vhost_vring_ioctl': drivers/vhost/vhost.c:818:3: error: call to '__compiletime_assert_818' declared with attribute error: BUILD_BUG_ON failed: __alignof__ *vq->avail > VRING_AVAIL_ALIGN_SIZE...

The header is not longer used and on alpha, ia64, openrisc, parisc and um it was completely unused anyway as these architectures have no highmem support.

Hi Everyone, I have been implementing the integrated assembler for the OpenRISC 1000 architecture. Whilst doing this I noticed a lack of documentation around this area. To help others, I have written a how to guide which uses the OpenRISC 1000 as an example. This can be downloaded from http://www.embecosm.com/download/ean10.html. I hope this document proves useful. Any f...

I am trying to follow this tutorial: http://llvm.org/devmtg/2009-10/Korobeynikov_BackendTutorial.pdf However, figuring out what can and cannot be deleted from the sparc backend while still compiling is proving rather frustrating. -Joe -------------- next part -------------- An HTML attachment was scrubbed...

...ng out what can and cannot be deleted from the sparc backend > while still compiling is proving rather frustrating. Why are you looking into sparc backend? I believe the talk makes clear which backend should be considered as a start point (at that time). In any case, https://github.com/asl/llvm-openrisc is better "stub" backend, at least it's 'just' 6 months old, not 3 years :) -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Hi, I'm working on a project that use llvm openrisc beckend (currently not part of the upstream). Right now I'm looking at a bug where llc generates memory instructions that has out-of-range displacement, for example l.sb 37668(r1), r2 in which 37668 is a 17 bit signed integer, but the instruction only allows 16 bit signed displacement. As a...

...different. I assume the newer one is better, but you > can look at both, shouldn't take too long. Yeah, right. The EuroLLVM one was a "refreshed" version of the first one. For example, there was no MC in 2009 and so on. The backend stub is available at https://github.com/asl/llvm-openrisc but given the LLVM development speed it's heavily outdated. Maybe it will make sense to look into new backends like SystemZ. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

I've been experimenting with building various llvm variants on mac OS X. Ususally, it's a case of cloning, running cmake with Xcode as generator and loading the resulting xcodeproj. In trying to build the skeleton openrisc backend from https://github.com/asl/llvm-openrisc as described in "building a backend in 24 hours" at http://llvm.org/devmtg/2012-04-12/Slides/Workshops/Anton_Korobeynikov.pdf, I find there are no cmakelists but there are llvmbuild.txt's. Is the llvmbuild somehow used to generate the...
