I'm using FunctionBuilder to translate my own basic blocks to cranelift IR. Is there an easy way to check if a cranelift Block has a terminator/is filled? Or do I need to keep track of whether I have added a terminator instruction myself? Thanks!
Jamey Sharp (Feb 03 2023 at 23:48):Happy to answer questions! You can use builder.func.layout.last_inst(block) to get the last instruction of a block (which will return None if the block is empty). Then builder.func.dfg.insts[inst].is_terminator() should tell you whether that instruction is valid for ending the block. But you might find it easier to keep track of this yourself.
