[LLVMdev] Thread-safe cloning
...esting
this approach (round tripping through bitcode in memory) and it works
beautifully - and isn't that much slower than cloning.
I have noticed however that the copy process isn't thread-safe. The
problem is that in Function, there is lazy initialization code for
arguments:
void CheckLazyArguments() const {
if (hasLazyArguments())
BuildLazyArguments();
}
void BuildLazyArguments() const;
I've worked around this by calling Function::getArgumentList() outside
the threaded code to harden it before the threaded copies. Are there
other lazy data structures that need to be...

[LLVMdev] Thread-safe cloning
You could probably round trip it through bitcode in memory. I think all of
the IR cloning functionality assumes that only one context is being used.
Even if the serialization isn't efficient as a clone could be, it should
give you very high confidence that everything Just Works. :)

[LLVMdev] Thread-safe cloning
I have a Module/LLVMContext that I'd like to clone and manipulate in
different threads (each thread may perform different translation /
optimization, so they need unique copies). Currently this process has
to be locked, since each clone of the Module still refers to the same
LLVMContext. Is there a way to clone both the Module and LLVMContext so
that the copies can be manipulated
