[LLVMdev] Calling between modules
...; development environment, and
then calling functions in one module from another module. Is this possible?
Basically, I want self contained chunks of code with dependencies on
functions in other self contained chunks that get resolved at JIT time. I
figured since the ExecutionEngine has an "addModuleProvider" function, this
sort of behavior is supported. If not, what is addModuleProvider's intended
use?
When I can get LLVM to do what I want, it is truly incredible! Thanks for a
great project!

[LLVMdev] Calling between modules
...ting
calls to the function in module A. I use new llvm::Function(type,
llvm::Function::ExternalLinkage, "myLinkedFunction", moduleB) when I
am defining the function with its body in module B. I then have an
ExecutionEngine which I constructed with an empty dummy module so that
I can use addModuleProvider and removeModuleProvider to link arbitrary
modules later. I call addModuleProvider with module A and module B
wrapped in ExistingModuleProviders, and call getPointerToFunction.
Any ideas? If there isn't anything obviously wrong here, I can boil
this down to a snippet that reproduces the pro...

[LLVMdev] Using a function from another module

This is somewhat tricky. To replace a function in-place like this, you
should actually modify the function in the origin...

[LLVMdev] Calling functions across modules. And those pesky vectors!
Before I get started with more questions, thanks for the prompt reply on
my last set question, that was much appreciated.
First, I found references to lazy inling and optimizations for calling
functions across modules, but I can't figure out how to do that. If I
just take a Function* that I got out of one module and call it from the
other, it doesn't work. What's the general
