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 interested: > > llvm-py 0.6 was released a couple of days back.

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, 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.

Hi, While playing around on the LLVM, I tried this code: int sum(int n) { if (n == 0) return 0; else return n + sum(n-1); } and this is what "llvm-gcc -O2" gave me: define i32 @sum(i32 %n) nounwind { entry: %tmp215 = icmp eq i32 %n, 0 ; <i1> [#uses=1] br i1 %tmp215, label %bb10, label %tailrecurse.bb10_crit_edge tailrecurse.bb10_crit_edge: ; preds =

....3 latest and Python 2.5 (2.4 should be sufficient, but 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. Version 0.3 of llvm-py, Python bindings for LLVM, has been released. llvm-py now supports reading/writing of bitcode and LLVM assembly files, intrinsics and all the transformation passes. Also included are bug fixes and documentation/test updates. Home page: http://mdevan.nfshost.com/llvm-py/ Thanks & Regards, -Mahadevan.

...LLVM, has been released. A few bug fixes, new APIs and code cleanup have gone in for this version. This will be the last release of llvm-py based on LLVM 2.3. Next version (0.5) will be based on LLVM 2.4 and will not be compatible with LLVM 2.3. I hope to release 0.5 very soon. Home page: http://mdevan.nfshost.com/llvm-py/ Thanks & Regards, -Mahadevan.

Hi, I tried to build llvm-py (http://www.mdevan.org/llvm-py/) using LLVM 3.0.1, and I got these errors in a few places: error: unknown type name ‘LLVMTypeHandleRef’ I did a quick search, and my guess is LLVMTypeHandleRef is not exist in LLVM 3 anymore: http://llvm.org/docs/doxygen/html/Core_8h_source.html So is there any equivalent? Maybe LLVM...

Hello All, llvm-py 0.2 has been released. IR, execution engine, and (some) passes are now covered. There is also a much better website; code is now hosted on google code. Visit http://mdevan.nfshost.com/llvm-py/index.html for more details. Thanks & Regards, -Mahadevan.
