Hello,
For code:
try {
throw 42;
} catch(int e){}
Are there any helpers in LLVM API to give me info that in “try block” there is a throw which will be executed? I am interested in info “yes, this block throws”.
Thank you

In LLVM IR, you would see an invoke
instruction that calls the appropriate C++ runtime function to set up a C++ exception. It would be __cxa_throw or CxxThrowException on Windows.
Since only function calls can throw, this is not a property of the basic block, but a property of individual call instructions.
