Hi all, Thought you might be interested: llvm-py 0.6 was released a couple of days back. This release is compatible with LLVM 2.7. Check it out at http://www.mdevan.org/llvm-py/. llvm-py has it's own mailing list, at http://groups.google.com/group/llvm-py. Regards, -Mahadevan. (author of llvm-py)

Hi Mahadevan, This looks very nice. Is there a good reason to maintain this outside of the LLVM source tree, or is this something you would like to see come in tree? - Daniel On Thu, Sep 2, 2010 at 10:58 PM, Mahadevan R <mdevan.foobar at gmail.com> wrote: > Hi all, > > Thought you might be i...

...ges committed in rev. 53212 broke LLVM build on openbsd-4.3 with gcc-3.3.5 (i386 and amd64). The attached patch fixes this. This looks like an issue with gcc-3.3.5, and I'm not sure if you guys will be wanting to support this compiler. Just sharing the patch hoping it helps someone.

Hi. Version 0.5 of llvm-py, Python bindings for LLVM, has been released. This version supports (only) LLVM 2.4. New instructions of LLVM 2.4 (vicmp, vfcmp, insertvalue, extractvalue) are available. Home page: http://mdevan.nfshost.com/llvm-py/ Feedback welcome. Thanks & Regards, -Mahadevan.

Hi, Are there Python bindings for LLVM? Apparently there was one ~2005; has this been updated since? Is anyone working on this? Is the LLVM dev community interested in this? Thanks & Regards, -Mahadevan.

Hi, While going through the list of intrinsics in Intrinsics.td, I found that it does not match the list given in Language Reference [1]. Does this mean that they are not to be used / don't work? Or is it just that the documentation is outdated? Thanks & Regards, -Mahadevan. [1] http://www.llvm.org/docs/LangRef.html

...problem in Python. This pattern is composable, which is an important property; Owner could play the role of Pet to some OtherOwner. But this is really delving into the realm of excessively elaborate, so I think I'll bow out now. Do whatever you think best. :) On May 13, 2008, at 04:31, Mahadevan R wrote: > On Tue, May 13, 2008 at 1:22 PM, Gordon Henriksen > <gordonhenriksen at mac.com> wrote: >> On 2008-05-13, at 02:12, Mahadevan R wrote: >> >>>>> That's not how the object works... >>> >>> Gordon, I think I can make it work if w...

...I haven't tested). Tested only on Linux/i386. Would love to hear your comments. [Needless to say, it's all work in progress, but mostly it works as expected. More tests, documentation and APIs will follow.] It's all here: http://mdevan.nfshost.com/llvm-py.html Thanks & Regards, -Mahadevan.

Hi, The LLVM Assembly Language Reference [1] incorrectly states that the prefix used for dll{import,export} is _imp__; it is actually __imp_. The attached patch fixes this.
