Follow-up from #66960. I also realized I don't understand our policy for using abort vs unreachable. AFAIK abort is safe to call and just aborts the process, while unreachable is UB. But sometimes we use both, like here

bx.abort();
bx.unreachable();

and here

bx.abort();
bx.unreachable();

The second case is even more confusing because that looks like an unreachable return to me, so why would we codegen a safe abort there?

Well that is curious:

error: failed to parse bitcode for LTO module: Invalid instruction with no BB (Producer: 'LLVM9.0.0-rust-1.41.0-dev-de1a7dbf6' Reader: 'LLVM 9.0.0-rust-1.41.0-dev-de1a7dbf6')

The second case is even more confusing because that looks like an unreachable return to me, so why would we codegen a safe abort there?

LLVM calls still require the rest of the block after them, even if the callee never returns.

You probably need to start a new block, or stop the remaining MIR statements/terminator from being codegen'd.

For now I made this an abort, also matching what we do for uninhabited returns. But it seems odd to me that we'd give those well-defined "trap" semantics as opposed to exploiting their UB.

LLVM calls still require the rest of the block after them, even if the callee never returns.

That explains the first case (the Abort terminator). But why does an unreachable return get translated to a well-defined abort (as opposed to an immediate-UB "unreachable")?

// We play it safe by using a well-defined `abort`, and not immediate UB.
bx.abort();

I am documenting existing behavior here, but my own inclination would be to remove the abort here to give the optimizer some more information. Or should we wait until someone determines that this is actually costing us some optimizations?

One difference between the two is that unreachable is an instruction (https://llvm.org/docs/LangRef.html#unreachable-instruction) while trap/abort is an intrinsic (https://llvm.org/docs/LangRef.html#llvm-trap-intrinsic).

I don't know what difference that makes though. Technically it should suffice to just emit unreachables.

The problem is that emitting unreachable followed by other stuff in the same basic block leads to ICEs.

Maybe emitting unreachable should "poison" the builder so any further commands trying to add things to the current block will just not do anything. The poisoning can be cleared when a new block is started.

Alternatively we could add some scheme where an Err(Unreachable) is bubbled up to the root code that generated it and then that code is supposed to stop generating the current block

The builder has a notion of "current block", right? Maybe after calling unreachable we should make a new block (with no incoming edge) and make that the current block.

But I don't know enough about our codegen APIs to implement any of these proposals.

Let's get this merged and I'll push making all of the traps unreachable onto my stack of PRs to make

Not all of them I hope. ;) The Abort MIR terminator should remain a well-defined trap.

😂 right, only those that are unreachable at runtime

Hang on, none of us know why the aborts are there!
Please don't remove any in the future without first talking to some codegen people who might know, or by finding a past decision by digging in the git history.

The problem is that emitting unreachable followed by other stuff in the same basic block leads to ICEs.

I didn't check but maybe LLVM produces an assertion if they are enabled (do you have them on?).
But the important thing is that this is a problem with all LLVM block terminators, LLVM will let you add more instructions to the block after the terminator, but it's malformed if you do.

As for "poisoning the builder"... Yeah that massive complication which we had for a very long time and which was made unnecessary by MIR 🤣

We can also monomorphize the MIR, rerun optimizations and have some guaranteed optimizations that cause no such weird code to even be given to llvm. The monorphized MIR can then be thrown away right after codegen. No need to keep it around

Fair.

OTOH, given there is no comment in the code, if there was anything subtle going on then someone seriously screwed up by not documenting it right...

codegen "unreachable" for invalid SetDiscriminant

Follow-up from rust-lang#66960. I also realized I don't understand our policy for using `abort` vs `unreachable`. AFAIK `abort` is safe to call and just aborts the process, while `unreachable` is UB. But sometimes we use both, like here

https://github.com/rust-lang/rust/blob/d825e35ee8325146e6c175a4c61bcb645b347d5e/src/librustc_codegen_ssa/mir/block.rs#L827-L828

and here

https://github.com/rust-lang/rust/blob/d825e35ee8325146e6c175a4c61bcb645b347d5e/src/librustc_codegen_ssa/mir/block.rs#L264-L265

The second case is even more confusing because that looks like an unreachable `return` to me, so why would we codegen a safe abort there?
