Since MCJIT I can't get libm functions to work
...declare float @cosf(float)
and would call it like:

The datalayout is set to
target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128"
The code snippet that adds the module is pretty much from the JIT tutorial:
auto Resolver = llvm::orc::createLambdaResolver(
[&](const std::string &Name) {
if (auto Sym =
CompileLayer.findSymbol(Name, false))
return Sym;
return llvm::JITSymbol(nullptr);

Linking existing functions from JITed code
...oscope examples have not worked for some time with

I’m using just the basic ORC CompileLayer directly.
So, I’ve essentially copied the ExecutionEngine::addGlobalMapping related
function to my JIT context, and I create a lambda resolver as such:
JITContext::addModule(…) {
auto Resolver = createLambdaResolver(
[&](const std::string &name) {
// look up first in JIT'ed code
if (auto sym = findMangledSymbol(name)) {
return RuntimeDyld::SymbolInfo(sym.getAddress(),
sym.getFlags());

[LLVMdev] Help with using LLVM to re-compile hot functions at run-time
Hi Again,
I'm a little confused regarding what is the exact Orc's functions I should
use
in order to save the functions code in a code cache so it could be later
replaced with different versions of it and I appreciate your help.
Just a reminder I want to dynamically recompile the program based on
profile
collected at the run-time. I would like to start executing the program
from

getSymbolAddressInProcess returning null
Tried that, still didn't work. Then I tried making a direct API call,
GetProcAddress(GetModuleHandle(0),"foo")
And this works if and only if __declspec(dllexport) is supplied. So it
looks like we were both right.
