So I've got my hands dirty with a cool project (who knows? maybe I'll end up releasing it), but since I'm fairly new to the whole thing, there are still a number of things I'm not

Felix, It really depends on what you are doing with the JIT. In my case, I have a scripting language that has a limited set of base data types. I wanted to be able to trivially interface to new C++ methods and classes, so I'm interfacing to C++ classes by creating external definitions much like the way Kaleidoscope accesses external C functions. I only have to deal with a few types so I can

Hello guys, I'd like to use Clang to parse snippets of (and emit bytecode for) C++ code that come from larger files that don't contain only C++, but looking at the clang interpreter example, either I didn't get it, or it looks like the driver expects only files, and not strings or char buffers. Is there a simple way to achieve this? Do I have to split my input into small files and

So I got very mixed results. With the CallGraphSCCPass, both `addRequired<DominatorTreeWrapperPass>` and `addRequired<MemoryDependenceAnalysis>` fail at runtime. The LLVM core has just two CallGraphSCCPasses and neither uses neither analyses, so it's hard to find a valid example. I transformed the pass into a ModulePass, using scc_iterator as shown in CGPassManager to process

Hey guys, I'd need to debug just-in-time compiled code under Mac OS. As predicted, GDB doesn't cope really well with it. The LLVM manual seems to say it's possible to patch GDB under Linux, but there seems to be no option for Mac OS. What can I do? I'd prefer a solution that integrates with Xcode, but I'll manage if it doesn't and I have to run the debugger externally.

Thanks Daniel, I'll do a debug build of LLVM (I guess that'll teach me) and step through it as soon as I'll find a power outlet. I'm calling getDependency on the load instruction, and it returns the store instruction. Suspiciously enough, calling invalidateCachedPointerInfo on load->getPointerOperand() does not cause my AA pass to be called again when I use getDependency (or

Wouldn't it mean each time a function is compiled it would need to be bundled to its own dylib? How well would that scale?

If so, you might want to have LLVM generate a full blown dylib, not just a JIT'd chunk of code and load the dylib using the standard shared

The semantics of C++ depend heavily on what comes before the given fragment. How do you plan to address this? For example, if you know all the headers you think these snippets will include, you can do something similar to PCH to parse the fragment in context of all of the headers. I don't know much about feeding clang buffers instead of files, but I believe it can be done with some of the

I'm assuming you're looking at this document? http://llvm.org/docs/DebuggingJITedCode.html That document should probably be updated to say you need GDB 7.0 or newer, since that's when the feature was released. Most Linux distributions have picked this up, so it should Just Work on Linux. Apple's GDB is stale (6.3 + lots of patches). They've stopped updating the version of

Hi all, I have a custom alias analysis pass that enforces that pointers from different address spaces do not alias, and I'm using MemoryDependenceAnalysis to, well, figure out dependence analysis. The AA pass is extremely simple, it only checks the address space of pointers, returns NoAlias if they're different, and delegates otherwise. It is the last alias analysis pass added to my

Thank you in advance. Although I have many years of experience in general, including cross- platform processing, I am not an HTML/Javascript programmer. As a result, I do not have certain specific baseline skills and/or knowledge that are presumed in the Rails and Ajax documentation. I am experienced with DOM manipulations, so the bare mechanics of manipulating the browser GUI via Javascript

Hi all, I work a lot with scripts that modify the DOM, and I have always found quite annoying that the code would always get very verbose as soon as I wanted to create even simple structures : var my_div = document.createElement(''div''); var my_anchor = document.createElement(''a''); my_anchor.setAttribute(''href'',my_link); var my_text =

Thanks John. Does this solve the problem of analysis availability though? If I still have to run the function analyses manually, I might as well keep rolling with the CallGraphSCCPass. (I probably should have mentioned that this is what I’m using right now.) Félix > Le 2015-05-19 à 10:12:32, John Criswell <jtcriswel at gmail.com> a écrit : > > On 5/18/15 10:45 PM, Félix Cloutier

Hi all, I have again noticed that the wiki does not really show up in search results and wonder if it has any impact that robots.txt on wiki.centos.org is empty. Perhaps it should at least contain User-agent: * ? Best Regards Marcus

I believe that what I'm trying to do with Clang is fairly simple; the final goal, however, might be a little harder. Knowing myself, there are chances I'll never go through with this project (like Mikael who posted earlier, I'm nothing but an enthusiastic student with lots of time on my hands), but it feels cool enough to me to announce my idea. Besides, I'll probably need help

I have a simlple view: <h2>Tags</h2> <% unless @recipe.tags.empty? %> <table> <tbody id="tags"> <%= render :partial=>''tags/tag'', :collection=>@recipe.tags %> </tbody> </table> <% end %> <% form_remote_tag :url=>tags_path(@recipe) do%>

The title says it all. verifyFunction checks it (Verifier.cpp, line 728). Why can't BasicBlocks that serve as a function's entry point also have predecessors? What keeps a function from looping back to its beginning? Félix -------------- next part -------------- An HTML attachment was scrubbed... URL:
