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

Hi all, How does this look as a potential FFI for our theoretical Ruby++ ? I''m not sure how to do mixins, though. Some sort of special directive? Or just add it to inheritance chain? Anyway, this is just a rough prototype. No attempt at an actual implementation yet. Regards, Dan // foo.h - Function prototypes #define _FOO_H_ using namespace ruby; // Subclass Object class Foo :

You're right, that probably won't have very good performance. What we (unladen-swallow) do is to call getPointerToFunction which gives a function pointer of type (void*)(void*) which we then cast to the appropriate function type and then call from C/C++. That way the C/C++ compiler for your application can codegen the function call once instead having the JIT do it many times. Reid On

While browsing the configure generated llvm/Config/config.h, I'm noticed that the macros: HAVE_FFI_CALL HAVE_FFI_FFI_H HAVE_FFI_H are not defined on OS X (currently 10.6.5). Given that ffi exists on this platform (both headers and lib), is this result intended? Thanks Garrison

Ah, --enable-libffi. Any pointers as why this is not a default check for at least UNIX systems? Does Windows have the equivalent?

I'm getting a segfault when I call `SDL_Init( SDL_INIT_VIDEO )` within the MCJIT.  If I compile the same program to an EXE I don't have a problem. Are there any general restrictions, or known issues, with loading a library like SDL2 via the MCJIT?  (LLVM-3.8 still) The stack trace, from GDB, is below. I noticed the error actually happens deep inside a transitively loaded GL drive module,

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, 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

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 went though a good amount of trouble to install the game, because you need to be in the UK to install it, but I'm in the USA. So I get it installed through a proxy and everything is good until I click it to start. It tells me it can't run it because of some bug. I don't know if you can help me or not. Thanks.

A colleague just asked if zfs delegation worked with zvols too. Thought I''d give it a go and got myself in a mess (tank/linkfixer is the delegated dataset): root at non-global / # zfs create -V 500M tank/linkfixer/foo cannot create device links for ''tank/linkfixer/foo'': permission denied cannot create ''tank/linkfixer/foo'': permission denied Ok, so

Ok do not know what is causing this problem and would appreciate some help in tracking down the cause. FreeBSD 4.7 System runs fine for maybe a week and then all networking stops - without warning. I do not know anyway of persuading it to resume networking without rebooting. Does anyone have some useful suggestions on how to diagnose the cause? David

Hi, I have a Toshiba Satellite L500 Laptop running 64bit Linux Mint Debian Edition 201109. The laptop has ATI Radeon M92 (HD 4500 / 5000) graphics. This is based on Debian testing and because at present there is no WINE in the testing repositories, I have installed 1.3.30 from: http://frickelplatz.de/debian/ This seems to work fine: I can run LTspiceIV perfectly. However ... I have tried
