OK, I solved it all ( so far :) ), mixing in some load-instructions and called on the result of that, which worked. Here is the skeleton-code: %kernel = type { int ()* } int puts_kernel(){...} ; main() %theKernel = malloc %kernel %puts_kernelPTR = getelementptr %kernel* %theKernel, long 1, ubyte 0 store int ()* %puts_kernel, int ()** %puts_kernelPTR %tmp.11 = load int ()** %puts_kernelPTR

So, here comes the next question:) Now the program compiles, but crashes when run, "Segmentation fault". %kernel = type { int ()* } int %puts_kernel() { ret int 0 } int %main() { %theKernel = alloca %kernel %puts_kernelPTR = getelementptr %kernel* %theKernel, long 1, ubyte 0 store int ()* %puts_kernel, int ()** %puts_kernelPTR ret int 0 } I want to learn how to

Hello! I'm having trouble with pointer traversing. I have a design as follows: class -> map -> classFunctions Starting with a pointer to the class, I want to get a pointer to a classFunction via a pointer to the map. I can't get that function pointer! How shall I think to get the traversing right (see code below)? Is it something with the fact that I am using only pointers in my

Hello! I get some odd behaviour using my structs: "myKernelMap" = type {int (sbyte*)*, int ()*} "Kernel" = type {"myKernelMap"*} The second member ( int()* ) is a pointer to the %getchar() function. I want to call getchar using this function: int "callmyKernelgetchar_kernel"("Kernel"* "myKernel") { "PTRMAP" =

Hello out there! I am trying to build a table of 2 function poiters by using an array: %kernel = alloca [ 2 x int ()* ] I try to access the first pointer to be able to store location of my first function like this: %function_pointer_1 = getelementptr [2 x int ()* ]* %kernel, long 0, long 0 store int ()* %function_1, int ()* %function_pointer_1 But, I get the error message from llvm-asm:

Yes! :-) What would I do without you folks?! I am the one trying to build a Ruby compiler prototype, so be prepared for more questions...:) Thanks again!

Hello! I am having trouble with identifiers: %tmpFunction = load int ()** %puts_kernelPTR ... %tmpFunction = load int ()** %puts_kernelPTR generates Redefinition of value named 'tmpFunction' in the 'int () *' type plane! Is it not allowed to reuse variables? Is there some way to do it? Anders ---------------------------------------------------------------- Anders

Thanks! Problem is though, that the Ruby compiler is integrated in the compilation of the program being executed, to be able to parse & compile dynamic code at run-time. Therefore the calls to ExecutionEngine::getPointerToGlobal(F) need to be made in LLVM code. Here is a detailed simplistic example in pseudocode of what we want to do: First Ruby code is entered at run-time, received as a

Great, thanks, it solved it!

Hello! I have compiled LLVM without errors and try to do a simple hello world test using the llvmgcc frontend, llvmgcc -o hello hello.c and I get this error message: gcc: installation problem, cannot exec `gccas': No such file or directory What have I one wrong/what needs to be done?

Hello! I am doing some pre-studies for my masters thesis, which (hopefully) will result in a compiler prototype for Ruby to LLVM, and I have a question: 1. When reading the reference manual, I do not understand how e.g. simple I/O operations as printf() can be implemented in LLVM. Are there any external functions available, or how do I proceed? Kind regards Anders

Hello! I saw that you just got the recent llvm paper published in IEEE! Congratulations! :-) More issues regarding the Ruby compiler: Ruby supports the possibility of the user to enter new Ruby code during execution, after which it is executed. Also, all classes are open, meaning that a user is able to redefine a class overriding or replacing methods therein at run-time (this is deep...). My
