[LLVMdev] Crash in JIT
Hi David, I'm not certain, but to me the "LLVMSetTarget(module, "i686-apple-darwin11");" line looks suspicious. I'm not familiar with all the ins and outs of how target triples get handled, but it looks to me like that's requesting 32-bit code. I think that if you omit that line completely then the target will be inferred from the execution environment. My best

mcjit C interface problems
Hi, I'm attempting to use MCJIT with the C interface with llvm-3.9.0, and it doesn't seem to work. This code is derived from Paul Smith's example code: int main(int argc, char const* argv[]) { LLVMModuleRef mod = LLVMModuleCreateWithName("my_module"); LLVMTypeRef param_types[] = {LLVMInt32Type(), LLVMInt32Type()}; LLVMTypeRef ret_type =

mcjit C interface problems
Thanks for the tip - getting closer: $ ./capi_test 5 6 args[0]: 5 args[1]: 6 result: 4294959200 Here's the code I changed: printf("args[0]: %d\n", (int)LLVMGenericValueToInt(args[0], 0)); printf("args[1]: %d\n", (int)LLVMGenericValueToInt(args[1], 0)); uint64_t (*func)(); func = (uint64_t (*)())LLVMGetFunctionAddress(engine, "sum");

[LLVMdev] JIT simple module and accessing the value fails
I'm using the llvm-c API and want to use the JIT. I've created the following module ; ModuleID = '_tmp' @a = global i64 5 define i64 @__tempfunc() { entry: %a_val = load i64* @a ret i64 %a_val } This output is generated by LLVMDumpModule just before I call LLVMRunFunction. Which yields a LLVMGenericValueRef. However converting the result to a 64bit integer via

[LLVMdev] LLVM-C: Calling functions contained in other libraries
Hello, I have a question concerning llvm-c. I have set up a function that needs to invoke an external method, in a other library. It has the following signature: void* NSFullUserName(void); The void* can be replaced with a i8*, that far I was able to get, but when my call is invoked, the engine gives me the following message: LLVM ERROR: Tried to execute an unknown external function: i8* ()*

[LLVMdev] Parameter names in IR and debug info
Have I correctly inferred below, how I build IR and debug info for a function type and a function (value), in particular, how to supply the names of the formal parameters? To create a function in llvm IR and give names to its formal parameters, I must: 1. Build a LLVMTypeRef for the type of each formal and the function result. 2. Build a function type using LLVMFunctionType, from the results of

[LLVMdev] Obfuscation with LLVM
Hi all, I was trying to implement an obfuscation tool for C-code on the basis of LLVM. I got a prototype of the simple obfuscation transformation which converting control flow graph to something like a state machine. I am not sure I will have time to work on extending further this tool with new transformations like opaque predicates and decided to put here source code I have by now with hope

[LLVMdev] loop only executes once
Hello, I'm trying to get to grips with the c interface of llvm intending to eventually develop a front end for Purebasic Though I've hit the wall already writing an iterative Fibonacci function. While I think the module dump looks ok it doesn't work for any input > 2 the function returns 2, the loop only executes once Hopefully someone can see what the problem is from the

[LLVMdev] RFC: llvm-shlib-test (Was: [llvm] r191029 - llvm-c: Make LLVMGetFirstTarget a proper prototype)
Attached is what I got thus far. What I'm struggling with is proper integration in build system. What is in there is just wild guesses from my side, both on autoconf and cmake variants. It would be great if someone with proper knowledge of the buildsystems could have a look. Also I'm not sure how to properly handle compilation on msvc - clearly "-std=c11 -Wstrict-prototypes" is
