Implementation is as follows: In preCheckExpression try to
detect if there is T(literal) call in the AST, replace it with
implicit literal as T, while trying to form type-checked AST,
after constraint solving, restore source information and drop unnecessary
coercion expression.

// Note that the error here is because of an implicit conversion of the input
// literal to 'Int'.
_blackHole(Float80(18_446_744_073_709_551_617)) // expected-error {{integer literal '18446744073709551617' overflows when stored into 'Int'}}
_blackHole(Float80(18_446_744_073_709_551_617)) // Ok

@xedin Nice to see that the above FIXME's are addressed by this fix. Thanks!

test/Sema/diag_erroneous_iuo.swift Outdated
let _: Optional<Int!> = nil // expected-error {{'!' is not allowed here; perhaps '?' was intended?}}{{20-21=?}}
_ = Int!?(0) // expected-error {{'!' is not allowed here; perhaps '?' was intended?}}{{8-9=?}}
_ = Int!?(0) // expected-error 3 {{'!' is not allowed here; perhaps '?' was intended?}}{{8-9=?}}

This looks like we're processing the type multiple times…

Yeah, we have that in a couple of places already unfortunately, because we don't track if we produced the same diagnostic multiple times...

Looking at the TypeLoc, we should see it has already been resolved to a Type, and not resolve the TypeRepr again. Where is the diagnostic being emitted?

Ah I see, it's probably my calls to resolveType which caused this, I'll try to fix it.

Done, just needed to cache the type in a couple of places :)

This semantic change isn't described in the proposal, and I think we wouldn't deviate from it. The rule as specified in SE-0213 is a clean syntactic rule that users can reason about. This tweak would come as a surprise.

If we need it for source compatibility, perhaps it would be best to put it behind !isSwiftVersionAtLeast(5).

I was just trying to avoid breaking existing code like https://github.com/apple/swift/pull/17860/files#diff-de58b3c2866a24533bc39d1bfd40fc3cR276 but maybe I shouldn't do it at all then?

Alright, this check is hidden under !isSwiftVersionAtLeast(5) now.

This is the use of string literals for selectors? I wonder if we can (separately) kill that now...

That's right, it's #selector(...) vs. Selector("...")

This is needed because constant propagation now looks at both branches, so as a way to work around that behavior @ravikandhadai and @moiseev told me that it would be appropriate to switch from @_transparent to @inlineable.

It is, unfortunately. @_transparent here causes the compile-time overflow on a branch that would not be taken at runtime.

Just to clarify. The changes to how initializers are resolved, as a side-effect, makes constant propagation more precise as it can now propagate through more initializers. While in general it is a good thing, in this specific case, it resulted in a false positive due to mandatory inlining.

Why not write return self < (0 as ${Self}) ? ~base &+ 1 : base? You are, after all, performing a bit twiddling operation.

It is very much possible (and probably reasonable) to try the &+ approach in a separate PR once this lands.

@moiseev @xwu there is one other issue with "magnitude" (besides the +) that could trigger static errors if it is made @_transparent. It is passing a potentially negative (builtin Int) into a UInt : let base = U${Self}(_value). This could trigger a static error on negative values like (-1).magnitude etc. So perhaps keeping it @inline is better.

No, _value is the same type regardless of whether it's Int or UInt, and that initializer simply assigns self._value = other._value.

@xwu Ah okay, this initializer should not be a problem for constant prop. There will no static errors here. Okay we can try making + to &+

[TypeChecker] SE-0213: Implement literal init via coercion
Implementation is as follows: In `preCheckExpression` try to
detect if there is `T(literal)` call in the AST, replace it with
implicit `literal as T`, while trying to form type-checked AST,
after constraint solving, restore source information and drop
unnecessary coercion expression.

[TypeChecker/SE-0213] Don't transform failable init calls into coerci…
…ons in Swift < 5

Maintain source compatibility, but only when Swift < 5, in cases when
type declares conformance to literal protocol and at the same time has
failable initializer with the same parameter type, see `Source compatibility`
of the proposal for more details.
