Dears, I'm trying to call the function that defined in the host application from IR code, but LLVM is saying that there is no such function... I've seen the tutorial of Kaleidoscope, and defined the function as extern "C" { void test1(void) { cout << "test function in the host application \n" ; } } ...in the host application. Would you please let me give any

Hi, I have a IR file generated by Clang: ; ModuleID = 'test_load_lib.c' target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-f80:128:128-v64:64:64-v128:128:128-a0:0:64-f80:32:32-n8:16:32-S32" target triple = "i686-pc-mingw32" declare i32 @a_outside_func(i32) define i32 @test_func() { entry: %call = call i32

I am just getting started with llvm. Here's code I am trying to compile: #include <stdio.h>#include "llvm/IR/LLVMContext.h"#include "llvm/IR/Module.h"#include "llvm/IR/IRBuilder.h" int main(){ llvm::LLVMContext& context = llvm::getGlobalContext(); llvm::Module* module = new llvm::Module("top", context); llvm::IRBuilder<>

Hello, I'm replacing a struct with another struct of a different size. A problem arises when the following line occurs in the source code: MyStruct *a = malloc(sizeof(a)); The 'sizeof(a)' is turned into a constant in the LLVM IR, resulting in the wrong amount of memory being allocated for the struct. Is there any way to find all the constants that have arisen from sizeof? Thanks,
