[swift-dev] Protocol Devirtualizer Pass

Hi, I am thinking about writing a Protocol Devirtualizer Pass that specializes functions that take Protocols as arguments to transform them with concrete types instead of protocol types when the concrete types can be determined statically by some compiler analysis. This is the first step of the tr

Re: [swift-dev] Protocol Devirtualizer Pass

The issue I raised is when we truly replace the type in an existing function: protocol Proto :class {} class SingleImpl : Proto {} class User { func useProto(p: Proto) {} } If i understand you correctly your pass changes this program to: class User { func useProto(p: SingleImpl) {} }

Re: [swift-dev] Protocol Devirtualizer Pass

Hi Raj, The way I would approach this problem is first, turn a function taking a protocol value into one taking a protocol-constrained generic parameter. So @inline(never) internal func wrap_inc(a:SumProtocol, val:Int) -> Int{ return a.increment(i:val) } Would become @inline(always) internal
