Hi Nadav (and others who are related to this issue) - I saw some discussions on loop vectorizer that you are planning to write. Do you foresee using Polyhedral Framework (polly project) in some way in that. Thanks J. -------------- next part -------------- An HTML attachment was scrubbed...

Hi I read on LLVM blog that meta-data has been implemented to coney debug information to run-time system. Can one use meta-data to convey developer specifc hints to run-time system (e.g. JIT compiler)? Keen to know your thoughts on this.

Hi all, Can anyone tell me the current state of instruction scheduling in LLVM, i.e. what all internal scheduling algorithms and whether constraint solving methods are used in LLVM for a single issue processor ? Please let me know if anyone has any information about it. Thanks, Siddharth -------------- next part -------------- An HTML attachment was scrubbed... URL:

...imizer. I think that we should start with the examples from the gcc vectorizer page[1]. Thanks, Nadav [1] - http://gcc.gnu.org/projects/tree-ssa/vectorization.html First, we need to check and see if Polly is the solution to the problems that we have.

Polly is already divided into analysis and transformation passes. However, the interface is currently specific to the needs of polyhedral optimizers. If there is interest to use e.g.

Hi: I have been working on Valgrind [porting it to non-supported architectures] and wanted to know what you guys think of Valgrind for LLVM. I haven't thought through fully myself - so wanted to get your inputs before becoming rigid in my own opinion. Original Valgrind works on object code - translating the asm to its own IR [intermediate representation]. But for LLVM, probably putting the
