similar to: [LLVMdev] Initial problems having installed LLVM

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? Regards Anders ---------------------------------------------------------------- Anders Alexandersson

I solved that one by substituting alloca into malloc, and forwarded the problem to actually calling the %puts_kernel function via my newly created function pointer. This works: %tmp.1 = call int %puts_kernel() This: %tmp.2 = call int %puts_kernelPTR() issues error: "Reference to an invalid definition: 'puts_kernelPTR' of type 'int () *'" How do I call the function

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 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

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

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 am coming back to the below discussion again, regarding the LLVM support of Ruby dynamics. The initial problem description is as follow, to refresh your memory :) After that my questions come: -----------BEGIN Initial problem description--------------- Problem is though, that the Ruby compiler is integrated in the compilation of the program being executed, to be able to parse &

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" =

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

LLVMers, If you're not working from the CVS "head", you can ignore this. Otherwise, please read it! I have committed changes to CVS head that require changes to your build environment. This is part of PR432. The changes involve getting the CFE to build an executable named llvm-gcc instead of gcc. The hyphenated name was chosen to be consistent with other LLVM tools, it is also

Ok, email the lists is preferred though, because then there is an archive, and others with similar questions can get them answered that way. I'm CC'ing the list because some of the info in my response may be useful to others.
