[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...

[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. :) On Tue, Jun 18, 2013 at 1:16 PM, Andrew Clinton <andrew at sidefx.com> wrote: > I have a

[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
