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

Sort of, yeah... constructs like union {double a; unsigned b[2];} in C depend on the endianness. > 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. You can't do FFI with incompatible ABIs in the general case without copying the data into structures appropriate for the target. Structs are laid out differently on...
