Hi, I am trying to compile a c program using LLVM and I am having trouble getting some static libraries included. I have successfully compiled those static libraries using LLVM and, for example, libogg.a is present, as is ogg.l.bc. However, when I try to build the final program, it does not include the static ogg library. I've tried va...
I have a project I'm trying to compile with alchemy. It will compile .o and .a files, but when trying to create a .swc, it will fail. It appears to crash with this error: g++ -swc -o mylib.swc my-flex-interface.cpp mylib.a Cannot yet select: 0x279c810: ch,flag = AVM2ISD::CALL - A call instruction 0x279c7a0, 0x29c4350 0 llc ...
Note: marked as community wiki. Where is the Low Level Virtual Machine in LLVM? I see that we have llvm-g++ and c-lang, but to me, a LLVM is something almost like Valgrind of a simulator, where instructions are executed on it, and I can write programs to instrument the running code / interrupt when certain conditions happen / etc ... ...
Is it possible to use llvm to run x86 programs? I.e. I want to use llvm as an x86 simulator to run x86 programs and then instrument the x86 program. Thanks! ...
Forgive me if this is a silly question, but I'm wondering if/how LLVM could be used to obtain a higher performance Z-Machine VM for interactive fiction. (If it could be used, I'm just looking for some high-level ideas or suggestions, not a detailed solution.) It might seem odd to desire higher performance for a circa-1978 technology, bu...
I am trying to make LLVM inline a function from a library. I have LLVM bitcode files (manually generated) that I linked together with llvm-link, I also have a library (written in C) compiled into bitcode by clang and archived with llvm-ar. I manage to link everything together and to execute but i can't manage to get LLVM to inline a func...
In the kaleidoscope parser / AST example at LLVM, the enum is given all negative values. Why the minus sign ? enum Token { tok_eof = -1, // commands tok_def = -2, tok_extern = -3, // primary tok_identifier = -4, tok_number = -5 }; ...
Does LLVM have lua bindings? I'm not interested in using LLVM as a backend /JIT for Lua. I want access to LLVM through lua. Thanks! ...
Hi, i'm currently building a small JIT compiler. For the language I need a runtime library for some special math functions. I think the best would be to compile the lib to bitcode and link it. The compiler should be integrated in a product and as of this, it must work under windows (VC10, 64bit). So is it possible to build the math li...
I'm in the process of implementing a cross-platform (Mac OS X, Windows, and Linux) application which will do lots of CPU intensive analysis of financial data. The bulk of the analysis engine will be written in C++ for speed reasons, with a user-accessible scripting engine interfacing with the C++ testing engine. I want to write several s...
After compilation next snippet of code with clang -O2 (or with online demo): #include <stdio.h> #include <stdlib.h> int flop(int x); int flip(int x) { if (x == 0) return 1; return (x+1)*flop(x-1); } int flop(int x) { if (x == 0) return 1; return (x+0)*flip(x-1); } int main(int argc, char **argv) { printf("%d\n", flip(atoi(ar...
I've seen some mkspec for mac or linux using llvm. Does anyone use an llvm compiled version of Qt ? Or llvm on their Qt Projects ? does it speed up compilation times ? Is your project faster ? ...
I have an LLVM (version 2.7) module with a function that takes a pointer to a struct. That struct contains a function pointer to a C++ function. The module function is going to be JIT-compiled, and I need to build that struct in C++ using the LLVM API. I can't seem get the pointer to the function as an LLVM value, let alone pass a pointe...
Are there any languages that target the LLVM that: Are statically typed Use type inference Are functional (i.e. lambda expressions, closures, list primitives, list comprehensions, etc.) Have first class object-oriented features (inheritance, polymorphism, mixins, etc.) Have a sophisticated type system (generics, covariance and contrava...
I've just tried compiling an iOS project using the the LLVM 1.5 compiler (included in XCode 3.2.3), and I got a lot of new warnings, including several like this: protocol qualifiers without 'id' is archaic For instance, this happens on lines like this: - (id)initWithContext:(NSManagedObjectContext *)context coordinator:(NSP...
Hey guys, I'm toying around with the LLVM C++ API. I'd like to JIT compile code and run it. However, I need to call a C++ method from said jitted code. Normally, LLVM treats method calls as function calls with the object pointer passed as the first argument, so calling shouldn't be a problem. The real problem is to get that function in...
I have recently started experimenting with LLVM under MinGW. I have read the Kaleidoscope tutorial but now I'm having problems with external functions. I'm declaring external functions like this: const Type* doubleType = Type::getPrimitiveType(ctx, Type::DoubleTyID); std::vector<const Type*> doubleParams; doubleParams.push_back(doubleT...
At the moment Scala runs only on the JVM, with an outdated implementation for the CLR. But there are some voices at the moment, that Microsoft is interested funding an up-to-date Scala port for .NET. Considering the lack of any plan or oversight at Oracle's side what to do with Java/the JVM/the ecosystem, how can a Scala developer be p...
If I build a static library with llvm-gcc, then link it with a program compiled using mingw gcc, will the result work? The same for other combinations of llvm-gcc, clang and normal gcc. I'm interested in how this works out on Linux (using normal non-mingw gcc, of course) and other platforms as well, but the emphasis is on Windows. I'm ...
I have no experience with llvm or clang, yet. From what I read clang is said to be easily embeddable Wikipedia-Clang, however, I did not find any tutorials about how to achieve this. So is it possible to provide the user of a c++ application with scripting-powers by JIT compiling and executing user-defined code at runtime? Would it be po...
