similar to: [LLVMdev] JIT functions' signature known only at runtime

I'm looking for an example of how to insert a new function into a module. I have a module pass that needs to create some new functions. Tia. Reed

Hello everyone, I've been trying to generate a C file using the llc tool, but I'm having a problem. I'm using a single Hello World program in C, and executing the following passes: clang -emit-llvm -c -o hello.bc hello.c  # getting the bit code of hello.c llc -march=c hello.bc                          # generating the hello.cbe.c file using the llvm C backend So far, nothing weird

Hi, I''ve been using FFI with a Ruby 1.9.3 built with MSVC++ and it''s been working well. One thing I''ve run into though is this: ffi_lib :msvcrt But that''s not the runtime I want. But I don''t want to hard code the runtime name either. I realize I could parse it out of RbConfig, but I was hoping for something nicer. Is there a way we could create an

Hello, I'm new to LLVM and I had a question about it: when we call the JIT::runFunction, since llvm doesn't has a full FFI, there are some cases in which the JIT needs to codegen a stub function to call the function we are interested, my question is: this stub function will remains in the module until when ? What are the most efficient way to remove it from the module and memory ? For a

Hi Eli, I think the llvm configure has already configured with ffi. ../llvm-2.6/configure -help | grep ffi --enable-libffi Check for the presence of libffi (default is YES) In addition, the printf() can work in program, reflecting that libffi is working, right? How can I make Interpreter work with getpid(), fork(), and clone()? On Thu, Dec 31, 2009 at 2:33 AM, Eli

Hey Daniel, I''m trying to leave you a comment on this article you wrote: http://djberg96.livejournal.com/168403.html But since you disabled OpenID and anonyous, I''m not fond to register for another account just to reply your comments. Quoting your post: "" Unfortunately, I''ve slammed into the cold hard fact that FFI just isn''t the grand solution

Hi Cristianno, This problem has been around for a while, ourselves we solve it with the following patches: https://hpcforge.org/scm/viewvc.php/trunk/patches/llvm.gpu.patch?root=kernelgen&view=markup https://hpcforge.org/scm/viewvc.php/trunk/patches/llvm.patch?revision=591&root=kernelgen&view=markup Please feel free to apply them, they *should* work for you even with the latest llvm

Hi, Try as I might, I just cannot get Dir.create_junction to work with FFI in the ffi branch of the win32-dir project. The problem is the REPARSE_JDATA_BUFFER struct. I''m just not sure how to set those members, specifically, the PathBuffer member. The target looks good, it''s UTF-16LE encoded, but I can''t make it work, despite trying several ways of defining the struct,

I can't seem to get LLVMCreateTargetMachine to work on my box (MBP i7 OS X 10.8). What should the values of triple, cpu and features be? I'm just looking for a way to get this up and going for now, I don't need specific optimizations. No matter what I send the function, I always get nil back. I'm giving it LLVMGetFirstTarget as the target value. Thanks for the help, Timothy

Hi, First of all, please note: as of v3.1, C backend has been thrown away for being "buggy" and "unmaintained". Several months ago there was a similar question, and it was solved. Please see the patch attached here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-March/047989.html Best, - D. 2012/8/18 xiaoyaollvm <xiaoyaollvm at 126.com>: > In llvm3.0,I use the llc

In llvm3.0,I use the llc to convert the IR to C code, But the code lack key words like "struct", Who can tell me how to modify the CBackend, 3Q ^-^ -------------- next part -------------- An HTML attachment was scrubbed...

Patch 9 is a kind of dumping ground of all kinds of stuff. It may be better to spend some time with git rebase -i trying to work this into more coherent patches.

Hello again, Thanks for the responses =) Dmitry, I have two points to comment: - First, I applied these two patches, and the .cbe.c file came out ok, except for one little thing -- the global variable was created with both modifiers: static and extern. Then, I just added a single guard to prevent this to happen (in a case of a variable having local linkage, the "extern" part was not

Hi Eli, Thanks for your reply. If I add -force-interpreter to lli, then it seems that it can not run external function like printf or malloc. Is there any easy way to solve this problem?

Hi Dale, yes it's just stack alignment. Unfortunately your patch doesn't make any difference. Thanks for thinking about this, Duncan.

I looked around for the status of OrcJIT FFI support. The last e-mail thread I could find was this one: Link <http://lists.llvm.org/pipermail/llvm-dev/2015-February/081679.html> Raw: http://lists.llvm.org/pipermail/llvm-dev/2015-February/081679.html Is OrcJIT now considered stable enough that there can be "official" exposed C APIs? If not, what's the standard approach if I
