This method can only be used on blocks that have a parent function. This is the correct point to insert copies at the beginning of a basic block. {ir-name}] [(attributes)].

Split the critical edge from this block to the given successor block, and return the newly created block, or null if splitting is not possible. Set this block to indicate that its address is used as something other than the target of a terminator, exception-handling target, jump table, or IR-level "blockaddress". The first segment is pretty simple: it creates an LLVM "module." In LLVM, a module represents a single unit of code that is to be processed together.
