Using `#[inline(always)]` and `become` together leads to LLVM failure

[InvalidPathException]

Code

Placeholder, I am trying to make a minimal example that reproduces the bug

A more messy example is here: https://github.com/InvalidPathException/wagmi/blob/tail/src/instance.rs
This code does not compile, at lines 315 or 1420, if you remove one of the #[inline(always)] it will compile.

Edit: No, must remove line 1420.

And this is not the entire problem, seems like we are having subtle ABI mismatches everywhere

My (not very educated) guess is that, tail call means handling the control to the callee, and it requires there to be no more code in the caller, but in-lining also means putting callee into the caller, perhaps this should be caught somewhere, instead of leading to an LLVM error.

[InvalidPathException]

We may close and un-link this issue, as I conflated the below issue (with fix PR) with the error caused by #[inline(always)], my bad. I will try to figure out the problem with #[inline(always)] and perhaps create another one.

#148239

Edit: They seem to be the same issue after all, #148240 fixed the #[inline(always)] problem. @WaffleLapkin should we close and unlink this from the parent issue?

[WaffleLapkin]

@InvalidPathException I'm honestly not sure what you mean. Was inline never an issue? Did it just surface another issue? In that case we can indeed close this.

Inline is caused by the same underlying problem fixed in #148240. #144986 is fixed too. They are all just different ways the same missing struct handling can break compilation.
