[swift-dev] Test Failures

[Ben Ng]

Tests are failing for me on a fresh checkout of master, on macOS, with --preset=buildbot,tools=RA,stdlib=RD

The failures in Interpreter fail with "LLVM ERROR: Compiler-internal integrated REPL unimplemented for this platform; use the LLDB-enhanced REPL instead."
I didn’t get these failures on Tuesday.

The failures in stdlib seem to be caused by warnings like these:

/Users/ben/Documents/code/swift-sources/swift/validation-test/stdlib/String.swift:683:15: warning: 'where' clause next to generic parameters is deprecated and will be removed in the future version of Swift
  S: Sequence where S.Iterator.Element == Character
             ~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

/Users/ben/Documents/code/swift-sources/swift/validation-test/stdlib/String.swift:1251:3: warning: 'where' clause next to generic parameters is deprecated and will be removed in the future version of Swift
  where
~~^~~~~

If I recall correctly, the stdlib tests have been failing for over a week. 

All the failing tests:

    Swift(macosx-x86_64) :: stdlib/String.swift
    Swift(macosx-x86_64) :: stdlib/NewArray.swift.gyb
    Swift(macosx-x86_64) :: Interpreter/repl_autolinking.swift
    Swift(macosx-x86_64) :: DebugInfo/variables-repl.swift
    Swift(macosx-x86_64) :: Interpreter/repl.swift
    Swift(macosx-x86_64) :: Interpreter/repl_13695499.swift
    Swift(macosx-x86_64) :: Interpreter/repl_17597453.swift
    Swift(macosx-x86_64) :: Interpreter/repl_conformance_lookup.swift
    Swift(macosx-x86_64) :: Interpreter/repl_diagnostics.swift
    Swift(macosx-x86_64) :: Interpreter/repl_hashbang.swift
    Swift(macosx-x86_64) :: Interpreter/SDK/Cocoa_repl.swift
    Swift(macosx-x86_64) :: Interpreter/SDK/missing_imports_repl.swift

Is there something wrong with my setup? Are these known failures?
