[LLVMdev] OrcJIT in LLVM C bindings
Thanks, David. I'd be happy to add the bindings .. is there a general way we add them? Or do you just scrub the API and make sensible judgements to the API?

[LLVMdev] stability of llvm ir across releases
Are you saying the textual form of IR can change, but bitcode doesn't? I don't know what you mean by assembly syntax. Is there a changlog entry when the textual IR changes?

why use profile likelihood for Box Cox transformation?
...ontains Y, not X. This relationship has some physical justification. I assume that these two approaches are not equivalent, is this correct? I assume the Box Cox approach (profile likelihood) is better, is this correct and why? Any help would be greatly appreciated. Thanks, Paul.

select text using only the keyboard
...could be done easily using just the keyboard, with up-arrow, shift-end or shift-home, ctrl-c, etc. But in R, the shift key doesn't select text. The only way I can select text in R is with the mouse. Does anyone know how to select text in R using only the keyboard? Many thanks, Paul. Paul Livingstone Statistical Analyst AeroStructures?

onFailure fails?
Hi all, I have this code: new Ajax.Request(''non_existant.file'', { onSuccess:function(){alert("yay");}, onFailure:function(){alert("boo");} }); Why does the onFailure alert never get called? It works fine if I use a real file (onSuccess gets called). Thanks, Douglas

[LLVMdev] unsupported GC: shadow-stack when using MCJIT
This is also happening when using the C++ APIs. It looks like an MCJIT and SetGC interaction. I'm lost on how to proceed further.

[LLVMdev] Calling into non-linked function via a pointer
This is my module's dump, which is different than yours.

[LLVMdev] Are global variables candiates for register allocation?
Thanks, Reid. I'm not an optimization expert, but as a workaround, can I do the following: void myFunction() { int local = global; .. use local ... } ?

Generating completely position agnostic code
It is wholly self-contained. It's code that has no references to anything beyond a set of pointers passed in as arguments to the function. This piece of code doesn't do any OS work at all. It is purely calling function pointers, doing math and allocating memory. On Mon, Jul 1, 2019 at 12:57 AM Jorg Brown <jorg.brown at gmail.com> wrote: > > Qs for you: > > The code that

[LLVMdev] OrcJIT in LLVM C bindings
Hello, I was wondering if there is someone already working on putting the new OrcJIT APIs in the LLVM-C bindings? Also, is there a general consensus to also add C bindings when new major features are added? Hayden -------------- next part -------------- An HTML attachment was scrubbed...

Generating completely position agnostic code
I'm on a mission to generate code that can be loaded from disk without any modifications. This means no relocations can occur. Trying to see if this can be done for C++ code that uses STL but has no global variables, and a single function, but of course Clang will generate more functions for STL code. I want to provide an array of function pointers so that for all interactions STL needs to

Clang/LLVM JIT - When to use "registerEHFrames()"
Historically? I implemented support for exceptions back in LLVM 3.3, before LLVM had an implementation of a Windows unwinder. Currently? As recent as LLVM 4.0, I don't think the JIT was fully capable of handling COFF files, and LLVM wouldn't emit the correct sections (with the COFF-formatted unwind tables) when used in ELF mode. The prolog is known to be standard since Julia disables FPO

llvm pdb utility question - how to convert real address to a segmented one
I've just started using the llvm-pdbutil tool. Great job on the general tool. But I'm having trouble figuring out how the output of the dump tool relates to real addresses in memory or for that matter relative virtual address either. Here's the logic I tried (which doesn't work): (1) Get Instruction Pointer of interest (2) Subtract the base address of the dll that address

[LLVMdev] [RFC] Developer Policy for LLVM C API
Can we also codify when something should be added to the C API? For a lot of folks the C API is the only usable interface. I am one of them. We are not as vocally represented because don't generally give back to the community, usually because we are just consumers of this library. (Or maybe I'm totally wrong and lots of us give back). For example, ORC APIs in C the bindings. On Fri, Jul

[LLVMdev] Are global variables candiates for register allocation?
Right, I follow your theory and thought the same. I have a single TU scenario where the global is just used because we generate hand assembly at runtime, and want to keep the code written by hand to be super simple, calls with no parameters. Our scenario is literally reading a file, which calls this functions hundreds of thousands of times, and we reset the pointer to the "global"

Improve JIT C API
Lang, aren't you going to be the major (only?) player when it comes to Orc APIs, if you're not opposed to it having them in the C bindings proper will certainly help. That's my vote, I understand it is different from the previous cases but the API surface area here is relatively small.

QUOTA support timeframe? (also -- folders in folders?)
I see it's been in the wishlist a while. Any possible timeframe for getting it working, or maybe a patch (or is it too big a change) to support it? I'm building a new server to move an existing userbase to. So far I have working: Postfix (with Maildir quota patches that work fine) Amavis-new with ClamAV scanning for viruses (will add SpamAssassin soon) SquirrelMail IMP (Horde)

[LLVMdev] unsupported GC: shadow-stack when using MCJIT
Thanks, Philip. I have a sinking feeling it's not your change, but could you share the commit and so I can try it out locally? Bug: https://llvm.org/bugs/show_bug.cgi?id=23095 The reason I think it is not your change is because I tried a shared library build of LLVM 3.5.1 and that also failed with this error. Maybe it is because I'm using a package that makes an LLVM DLL for Windows.
