...out of archives, then you should use an LTO enabled linker (either the system linker on OS X, or gold + the gold plugin on Linux).

On Darwin, if -march is armv7 clang's driver will assume you want thumb2 unless you also give it -mno-thumb but that is irrelevant with mcpu=cortex-m3. I agree its a mess. -Chris On Jul 22, 2012, at 4:37 PM, Renato Golin wrote: > On 22 July 2012 20:42, Anton Korobeynikov <anton at korobeynikov.info> wrote: >>> Any suggestions? >> Try to specify CPU explicitly. >

Teja, Your mention of .s being bytecode confuses me, but if you're asking how to lower a bitcode (.bc) or IR file (.ll) to assembly (.s) than llc is the tool you are looking for. llc -O2 path/to/bitcode/input.bc -o output.s -Chris On Mar 7, 2013, at 10:39 PM, teja tamboli wrote: > Hello, > > I am looking for tool to convert file from either (.s) bytecode or (.bc) bitcode to

Hello, I am looking for tool to convert file from either (.s) bytecode or (.bc) bitcode to .asm file. Basically assembly instruction file for my x86 backend. I think so we can use llvm-objdump. However I am not able to figure out its exact options. Could you please tell me how to do that? -- Thanks, Teja -------------- next part -------------- An HTML attachment was scrubbed... URL:

This is a big mess... I thought that v7 always assumed Thumb2 for the thumb flag, and v7M should always assume Cortex-M3 CPU if none provided. It's funny that James had a great

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<>

...-emit-llvm gives me errors $clang++ try.cpp -D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS -S -emit-llvm $ lli try.s gives me Program used external function '_ZN4llvm16getGlobalContextEv' which could not be resolved!

You may also need to use: -mllvm -enable-correct-eh-support -mllvm -arm-enable-ehabi-descriptors -Chris On Feb 4, 2013, at 3:47 PM, Abdoulaye Walsimou Gaye wrote: > On 02/04/2013 09:32 PM, Anton Korobeynikov wrote: >>> am I wrong or the ARM c++ exceptions handling does not work? >> Yes, it's still work-in-progress option disabled by default.

Looking at /tools/llvm-link/llvm-link.cpp may give you some ideas here. I havent looked at your specific use case, but llvm-link uses ParseIRFile to pull in a bitcode file and build a Module for it. You can then create a Composite using the Module * and call Linker::LinkModules(Composite.get(), NewModuleToLink.get()... to link a new Module to your Composite Module. -Chris On Feb 14, 2013, at
