LLVM doesn't use exceptions in anything that has C bindings, so the catch isn't needed. > [OT: Does clang warn

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 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. 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 all, I'd like to announce the availability of Python bindings for LLVM. It is built over llvm-c, and currently exposes enough APIs to build an in-memory IR (and dump it!). It needs LLVM 2.3 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

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 =

Nope, there's still a lot that's not done. Patches are always welcome :) We've got enough in subversion to implement the Kaleidoscope tutorial though. > 2) > Do

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.

Hm. I may misunderstand, but I'm not sure that's an improvement over the problem you're trying to solve. How about something like this? (Please forgive any accent; I don't speak snake fluently.) class Pet(object): @staticmethod def new(): # Create a 'free' pet. It can later become owned, but not to more than one owner. return

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.
