We recently ran into this. Unfortunately

How does the LLVM JIT determine the ABI and architecture to generate code for? I ask because I have an armhf device (running Debian, sort of), except the JIT is generating soft-float code. This isn't ABI compatible as parameters are passed in the wrong registers, and so simply doesn't work. Is this something that I, as an LLVM library user, should not need to worry about (and therefore

I'm using the Debian LLVM package to try and do JIT on a Linux armhf device. Unfortunately it seems to be generating armel code rather than armhf code, and since the ABIs don't match nothing works. I've tried overriding the triple to arm-unknown-linux-gnueabihf and arm-linux-gnueabihf (via module->setTargetTriple), and while the triples are accepted, the actual generated code

I have a simple expression-evaluation language using LLVM (it's at https://cowlark.com/calculon, if anyone's interested). It has pretty primitive support for 3-vectors, which I'm representing as a <3 x float>. One of my users has asked for proper n-vector support, and I agree with him so I'm adding that. However, he wants to use quite large vectors. He's mentioned 30

I can see why freakishly large vectors would produce bad code. The type <50 x float> would be widened to the next power of two, and then split over and over again until it fits into registers. So, any <50 x float> would take 16 XMM registers, that will be spilled. The situation with integer types is even worse because you can truncate or extend from one type to another. On Feb 6,

HI all, Having fixed the group issues from solaris having a default max of 16 groups I can now locally create and delete files on the solaris box as a domain user However when accessed via samba I can not create new files/folders (although I can delete the files I created when logged on locally) I have created a temporary directory on a non zfs (non acl enabled) file system to see if that

Hi all, I have a Solaris 10 (update 4) box (x86) that is joined to an active directory via samba/winbind (3.0.25c version included with Solaris including latest patches). The users are working fine however their group membership is not. Users that should be members of certain groups do not seem to be: in that if I run 'groups' and check the group member ship for my domain account I am

Hi all, Somewhat of a newbie's question, hope you can help me out. I'm trying to turn unconditional BranchInst's into conditional ones (with a condition I'm supplying) branching between the original target and a basic block of my choice. Apparently the way to do that is to create a new conditional BranchInst and remove the unconditional one from its basic block. However when

Hi, The attached patch does a few separate things. I can split them up if you like but it's pretty small. - Adds support for sniffing PE/COFF files on win32 (.exe and .dll) which are COFF files that have an MS-DOS compatibility stub on the front of them. - Fixes a bug in the COFFObjectFile's support for the Microsoft COFF extension for long symbol names, wherein it

Hi, As I understand it, the issue is that (at least in principle) the information in any of the C/C++ system headers can be different between different architectures (and even major versions of the standard library on a given architecture). As such, clang/clang++ attempts to find the system header file for the target architecture rather than the host, and for general code there's no way to

I believe it's failing on 64-bit because that's a 32-bit indirect jump. 64-bit needs jmp *%rdx.
