Calling LowerSwitchPass causing crash in llvm 9
There is no “switch” instruction in the target object code. It usually gets compiled into a switch table with instructions to load from it. Afaik

Calling LowerSwitchPass causing crash in llvm 9
Hi,
I am trying to call LowerSwitchPass directly in my custom pass in this way:
FunctionPass *lower = createLowerSwitchPass();

But it will crash when running lower->runOnFunction(*f) in llvm-9.
I was using this method in llvm-8 and it worked fine. It seems the crash
happens at the first line of the LowerSwitch::runOnFunction(Function &F) in

Can't find symbol from llvm backend
Hi, I am new to llvm.
I create a global variable called "test_llvm_var" in the front end function

new GlobalVariable(*m, tmp->getType(), true,
llvm::GlobalValue::ExternalLinkage, tmp, "test_llvm_var");
where tmp is a function.
Then I tried to access this global variable in the back end
MachineFunctionPass like this:
