The last good merge commit was: bc61e6adee
The first bad merge commit was: 0d6ac8f2cb
The commit where it broke was 7e77bc4d87. This commit only changes a
test and shouldn’t have affected the failing test.
I'm disabling this test for now since we need to rebranch.
Way back in Swift 1 I was trying to draw a distinction between
"overlays", separate libraries that added Swift content to an existing
Objective-C framework, and "the Swift part of a mixed-source
framework", even though they're implemented in almost exactly the same
way. "Adapter module" was the term that covered both of those. In
practice, however, no one knew what "adapter" meant. Bring an end to
this confusion by just using "overlay" within the compiler even for
the mixed-source framework case.
No intended functionality change.
