Hi, Looks ok for native MIPS, I have two failures on debian8: Failing Tests (2): XRay-x86_64-linux :: TestCases/Linux/argv0-log-file-name.cc XRay-x86_64-linux :: TestCases/Linux/fixedsize-logging.cc I'll investigate these failures. Otherwise looks ok. I've uploaded the binaries. 9d5a389c20eb5b3071e6a0504b7cf87d clang+llvm-4.0.0-rc1-mipsel-linux-gnu.tar.xz

Dear community, I will be leaving MIPS on the 20th to pursue other LLVM based endeavours. As such, I am stepping down as code owner. My apologies for the timing with regard to the current release, I had hoped that the process would have be complete by then. I would like to nominate Simon Atanaysan as the new code owner for the MIPS backend. Thanks, Simon -------------- next part

Hi all, I plan to deprecate the experimental microMIPS64R6 backend for the 5.0 release and remove it after the release. Currently there are no CPUs that use that particular sub-ISA which makes it difficult to justify the maintenance and parallel development effort. If there was a CPU design produced that did use microMIPS64R6, the backend could be restored from the archive. Any comments or

...on to a different LLVM opportunity at Apple a few weeks later. As such, I feel it's time for me to step down as code owner of the Mips target so that we have a single code owner throughout the LLVM 3.9 release which is scheduled to finish just after my last day. I'd like to nominate Simon Dardis as the new code owner. Is that ok with everyone? Vasileios Kalintiris is going to take over my release testing, starting with the 3.9 release. He will also be taking over my buildbots over the next few weeks. Daniel Sanders Leading Software Design Engineer, MIPS Processor IP Imagination Technolog...

I've prepared a preliminary patch with the intention of implementing PPC-EABI subtarget features for applications that run in a standalone embedded environment. https://reviews.llvm.org/D26344 The most significant difference compared with the SVR4 ABI is the use of SDA (small data area). This allows full-word constants and data to be grouped into small-data sections accessed using relocated

...ssfully using the backend in Linux. OTOH, FreeBSD is "almost there", and not sure about NetBSD and OpenBSD. In the case of MIPS, would Linux be the most reliable choice, or is any BSD flavour already using the backend successfully?

...tension of the MIPS ISA. VMIPS appears to be an implementation of the R3000 that's intended as a teaching tool. Does your MIPS CPU have this extension? > Did anyone think of implementing in the LLVM Mips back end (part of the MSA vector instructions) gather and scatter operations? Simon Dardis would be able to confirm but there aren't any as far as I know. The closest I can think of is in MSA where you can get a similar effect with a sequence of ld.df's and vshf.df's (or pck*.df's, ilv*.df's, etc. for some of the common cases). > If so, can you share with me th...

I looked around the codebase and didn't see anything that obviously looked like the natural place to turn constant zero immediates into zero-registers (i.e. registers that always return zero when read). Right now we are expanding them in ISelLowering::LowerOperation but that seems too early. The specific issue I'm hitting is that we have a register that reads as -1 and so when we replace

Dear testers, 6.0.0-rc3 was just tagged, after r325901 on the branch. There are still a few open blockers, but I'm not sure we'll actually end up blocking on all of them. So depending on what comes up, this release candidate is probably pretty close to what the final release will look like (I'm still hoping for more release notes, though). I'm hoping we can get to

Hi, I'd like to experiment with the MIPS and PowerPC backends, but, considering that they aren't widely used processors, I'd like to start with the same environment (OS/ABI/linker) used by the people who work with these backends. So, what OS/ABI/linker use the people who use these backends for production work? Thanks!!
