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 w...

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...

Quoting your post: "" Unfortunately, I''ve slammed into the cold hard fact that FFI just isn''t the grand solution we all hoped it would be. The first problem is that libffi, the underlying source for C based implementations, isn''t going to build without the gcc toolchain. That pretty much leaves everyone but Linux, FreeBSD and OS X in the dust, including two heav...

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...

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

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_ us...

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, 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 little quantity of calls this do...

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

...; your interpreter map memory backwards on opposite-endian platforms? Hi The front-end is not C code, and doesn't do bit-level operations (if that's what you mean). My first attempt was indeed to just leave memory in big endian and swap during loads/stores. But, I'd like to support an FFI to native code (which of course doesn't have any knowledge of having to swap memory), so that isn't too practical. thanks, scott
