similar to: [LLVMdev] Is there a "callback optimization"?

When I used -std-compile-opts -disable-inlining, my transform didn't happen. I think in your test, the inline of UseCallback into foo automatically made the function pointer into a constant, which turned it into a direct call that was then inlined. If UseCallback is too big to inline and uses the callback parameter inside a loop, this transform is potentially valuable, particularly if

It should be relatively simple to write a pass that turns each call that has constant argument(s) into a call to specialized version of the callee. To devirtualize C++ calls it needs to be smarter, since the argument is not a constant, but a pointer to a struct that points to a constant. However, the trick here is 1) Knowing when to perform specialization. If the call was not inlined the function

Dear all, my aim is to integrate R in an interactive visualisation software called Bulk Analyzer developed by VrVis (http://www.vrvis.at). the code: SEXP e, tmp; ParseStatus status; PROTECT(tmp = mkString("x <- c(1.234,-3.45)")); PrintValue(tmp); PROTECT(e = R_ParseVector(tmp, -1, &status, R_NilValue)); PrintValue(e); UNPROTECT(2); produces the following output: [1] "x

Hi Geoff, Nothing in that backtrace leaps out at me. Based on the stack trace and description my first guess would be a clang misconfiguration rather than a JIT bug. How is that clang invocation being made? Is it from inside a callback from ORC, or is it before you add your module to the JIT? -- Lang.

Hi, That patch was from an ongoing effort to consolidate OpenMP generation in clang. If memory serves the implementation there is still a little incomplete. It's supposed to use types from OMPConstants rather than ones it defined itself and the methods used to create the functions shouldn't need to be static. However attempting this caused a lot of errors so there might be an underlying

Thanks, Joseph and Johannes. I have not merged in anything, I am using the code from the repository as is. What is this -debug-only option, and to whom would I pass it? I am running our own JIT application, which uses clang to compile modules on the fly via clang::CompilerInstance::ExecuteAction(). Working on the assumption that there is a mismatch in the declared type of an OpenMP runtime

Yep, it happens three times, then crashes afterwards, since I removed the assert... arg 0: expected %struct.ident_t* got %struct.ident_t.21* value @0 = private unnamed_addr global %struct.ident_t.21 { i32 0, i32 514, i32 0, i32 0, i8* getelementptr inbounds ([23 x i8], [23 x i8]* @.str, i32 0, i32 0) }, align 8 arg 0: expected %struct.ident_t* got %struct.ident_t.21* value @1 = private

Hello all, I want to extend a draggable object so it has one more attribute (type attribute, so I can distinguish different draggable types). Can anyone tell me how to do it? I''ve search throught the examples (like http://wiki.script.aculo.us/scriptaculous/show/ExtendClass) but I can''t seem to understand what I should do. Thanks for you help, H

Dear r-helpers, I have been trying to invoke R from Java in a Windows 2000 computer (unfortunately). All my environment variables seem to be properly set, everything seems to be in order, but I obtaining a Fatal error: unable to open the base package error window. Also, the output of the invoker is Loading RInterpreter library R_HOME: R_HOME=C:/Programas/R RVersion: R_VERSION=1.6.1 whereas

Yeah, I remember encountering that error before when getting it to pass the libomp test suite. If you have a struct named "ident_t" somewhere the compiler will rename it because of the conflict with the runtime declaration. This should be solved by casting the usage to the function type found in the definition (i.e. bitcasting a struct.ident_t.21 to struct.ident_t) which solved the

Greetings, Lang and other JITters, Last week I moved our Orc v2-based app from top-of-tree to the new 11.x branch, and it no longer handles C++ code containing OpenMP directives correctly. More specifically, if I JIT compile a function containing OpenMP parallel/for pragmas, using a release version of LLVM, the code compiles and seems to work, but if I try to write the module's bitcode to

So I have found how to generate json in a rails app in the wiki (http://wiki.rubyonrails.com/rails/pages/HowtoGenerateJSON), what I have yet to figure out is how to make a synchronous call via json to rails so that I can block while fetching the information from a user request. context: I have used JSON on top of java in the past, and in order to make synchronous calls I had to do the

Hi there I''ve been running BackgroundRb in production for a few months now. Recently we added encryption onto some of our ActiveRecord fields by hooking in the before_save and after_save callbacks, like: class MyCallback def initialize(attr_names) @attr_names = attr_names end def before_save(model) @attr_names.each do |attr_name| next if

I am making a lightweight opus audio player. This is my portaudio callback function. But i hear a stammering song when i try to play a .opus song file. Can anybody say what is wrong or provide me link to any code which can play opus file written in c/c++(light). I tried to see some open source(vlc opus play) but was unable to follow. int MyCallback(const void* input, void* output, unsigned

Sorry for asking this question again but before I blow 100 dollars on a X100P I need to know this info: So does "SET EXTENSION <new extension>" allow for you to set which extension the rest of the call will occur over? So if a call comes into the switch and I could make the AGI script check the DID or DNIS which is really in the variable agi_dnid? After that I can do a database

Hello all, I have a Samba 3.5 server running in an AD domain and domain users can access nonpublic shares with their credentials. Good since this is what I want. However accidentally I found that local users (of the server itself) could also access nonpublic shares with their credentials. Is this a bug or Samba works this way, accepting both local and domain users? Is there anyway I can make the
