Hi. The attached patch adds wrappers for the instructions vicmp, vfcmp, ret (multiple) and getresult, and for the vicmp and vfcmp operations on constants, to llvm-c. Also: 1) There appears to be no way to create intrinsics via llvm-c. Is there? 2) The "extractvalue"[1] and "insertvalue"[2] instructions don't seem to be addable via IRBuilder. Why? Cheers, -Mahadevan.

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, I have some questions as to the definition of various vector instructions. In particular, I believe there are some gaps and inconsistencies in the vector instructions, and I'm interested in hearing whether you agree that these should be improved or whether there are other ways to solve these problems. === 1. Shufflevector only accepts vectors of the same type Shufflevector seems overly

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, We would like to extend the vector operations in llvm a bit. We're hoping to get some feedback on the right way to go, or some starting points. I had previously had some discussion on this list about a subset of the changes we have in mind. All of these changes are intended to make target-independent IR (i.e. IR without machine specific intrinsics) generate better code or be

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

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.

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.

Hi. Version 0.4 of llvm-py, Python bindings for 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,

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 =

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.
