Hi Jeffrey, This looks very good. Thanks. Some comments: +/// JitSymbolEntry - Each function that is JIT compiled results in one of these +/// being added to an array of symbols. This indicates the name of the function +/// as well as the address range it occupies. This allows the client to map +/// from a PC value to the name of the function. +struct JitSymbolEntry { A nitpick. Please

I intend to use this to support oprofile's ability to symbolize JITted code through the interface described at http://oprofile.sourceforge.net/doc/devel/jit-interface.html. I believe the interface will also be useful for gdb support. I'm considering adding some flags to the JITEventListener to let the JIT avoid collecting information no listener is going to use, but I won't do that

Ack, sorry. I should have sent this to llvm-commits instead. :-P Followups there please.

Having something like this available in tree would definitely be useful. For simplicity, why don't we start with support for the second style? This is the long term useful one and would be a good starting point for getting the code in tree. Can you give a pointer to the patch so that I can assess the rough complexity? If it's simple enough, I'd be happy to help get it reviewed

Hi, Under linux a large portion of the profiling these days happens with perf, but there's no support for it from LLVM's JITs. For a while perf could associate address+size to symbols by writing a /tmp/perf-$pid.map file: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/tools/perf/Documentation/jit-interface.txt A year or so perf also gained the ability to actually

Hi All, Just a couple of updates this week: First: there is a preview patch up at https://reviews.llvm.org/D75838 to enable use of JITEventListeners in RTDyldObjectLinkingLayer. I've only done very preliminary testing on it, but was able to debug simple JIT'd programs on Linux using the GDB registration listener. If you've been wanting to move to ORC but held up by lack of debugger /

Hi, I am working on using LLVM to compile parts of longrunning PostgreSQL queries into native code for faster code execution. As postgres is, nearly, entirely written in C and has long-lived (5 years) supported branches (making the higher API stability important), I'm currently using the C API. I started out using MCJIT but it looks like that's slowly on the way out. My current concern

Also https://www.r-project.org/posting-guide.html indicates that RSiteSearch() within R searches R-help but in my install (3.4.3) RSiteSearch() only searches?

Hi there, I'm having trouble getting ExecutionEngine->runStaticConstructorsDestructors(module, true) to actually trigger static destructors in my code. The static constructors however do get called. I don't know if this is an LLVM or Clang issue, from looking at the IR (see below) it looks like the destructor is being tied to cxa_atexit, and I wonder if that is not called by

I am new to this listand am unable to get the search tools listed on https://stat.ethz.ch/mailman/listinfo/r-help towork. What do people use to search the help archives? 1. The google search box on http://tolstoy.newcastle.edu.au/~rking/R/ returns a 404 error. 2. The http://finzi.psych.upenn.edu/ site has many references but I don't see how to search r-help from there. 3. The

Thank you all for these suggestions.

Hi Andy, In the NotifyObjectEmitted method of our derived JITEventListener class we use the begin_symbol() iterator to walk the object's symbols looking for functions and only functions marked with ExternalLinkage seem to show up. I'm not sure how I would access the Dwarf info from within there, is there a way? Thanks, Andrew On Wed, Nov 13, 2013 at 8:23 PM, Kaylor, Andrew

Hi All, I realise this is off topic, but its likely the best place to ask! I sent an email to snom support a few days ago but have yet to recieve a response.. Perhaps some one has found a solution to this problem already? I've searched the mailing lists and google and found nothing useful. I've also read Snom's mass deployment documentation but thats no real help in this case.

We implemented a similar solution for handling crashes in production but one issue we came across with MCJIT was that the NotifyFunctionEmitted call from the old JIT was replaced with NotifyObjectEmitted. The ObjectImage used by NotifyObjectEmitted does have a way of iterating symbols but non-external functions used in the module didn't seem to appear in this list so we were left with some
