Yeah, that's probably how I'd do it. Might be useful if you guys want to contribute that as a command line option Kevin. -eric On Tue, Jun 24, 2014 at 3:03 PM, Kevin Modzelewski <kmod at dropbox.com> wrote: > We do this in Pyston using a JITEventListener that just disassembles the > output; it's "it works let's move on"-quality: >

Dear, I am actually using llvm ocaml binding to generate LLVM IR code. Can some one tell me how to use the binding to generate debug informations if it's possible ? Many thanks --- | J.

Jon, I need to create a database of basics blocks and their execution time. The only thing I'm concerned is if a block A is more expensive than a block B. Do you think that even with the overhead I would be able to get the A > B information? Like: overhead + time(A) > overhead + time(B) => A > B. If so, I'm not too much concerned about the accuracy. Not sure if I was clear,

I want to measure the performance of a JITed code snippet on MCJIT. so I was planning to inject the RDPMC inst for the code generated through a llvm IR builder. Is there a patch available ? If there's a better way to do it please chime in. Thanks sathvik -------------- next part -------------- An HTML attachment was scrubbed... URL:

I believe the perf tool cannot profile/analyze the JITed code in MCJIT model. Can you please confirm this ? I was working on a patch to fix this. Another question, is the there any support to map the llvm IR with x86 generated assembly ? so its easier to analyze the code generator. -------------- next part -------------- An HTML attachment was scrubbed...
