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<>

How does LLVM generate machine code for different architectures? For example, the machine code for x86 and amd will vary. How does LLVM convert its IR to machine code for different architectures.Can you please explain the approach? Is it just write two different programs for two different architectures and pass a flag to the compiler based on which machine code you want to generate? Thanks a lot

Hi, I am trying to write a simple interpreter. I am trying to generate LLVM IR for assignment operation. The code for the generation part looks like this llvm::Value* codeGenSymTab(llvm::LLVMContext& context) { > printf("\n CodeGen SymTab \n"); > Value *num = ConstantInt::get(Type::getInt64Ty(context), aTable.value, > true); > Value *alloc = new

Hi, I am planning to use LLVM in my compiler dev project. I would like to know what power LLVM code optimization phase provides to my code ? I had a look at http://llvm.org/docs/Passes.html which describes the optimization passes. >From a newbie standpoint can you please explain the power of LLVM optimization?

Hi, I have written a c program which accesses sqlite database. Normally I compile the program as $ clang insertselect.c -l sqlite3 To emit-llvm I use: > $ clang insertselect.c -S -emit-llvm How do I link the sqlite3 library so that llvm can generate IR with the IR being linked to the external library? Thanks for your help? Thanks Prakash -------------- next part -------------- An
