Always parse macro expansions, regardless of language mode, and eliminate the fallback path for very, very, very old object literals like `#Color`. Instead, check for the feature flag for macro declaration and at macro expansion time, since this is a semantic restriction. While here, refactor things so the vast majority of the macro-handling logic still applies even if the Swift Swift parser is disabled. Only attempts to expand the macro will fail. This allows us to enable the macro-diagnostics test everywhere.

// Tests the diagnostics emitted when we can't build a module interface, and
|
|
// particularly whether or not they call out compiler version mismatches.
|
|
//
|
|
// First, emit an empty module interface from the current compiler, then add
|
|
// some invalid syntax to it:
|
|
//
|
|
// RUN: %empty-directory(%t)
|
|
// RUN: echo "" | %target-swift-frontend -typecheck -emit-module-interface-path %t/UnbuildableCurrent.swiftinterface -enable-library-evolution -swift-version 5 -module-name UnbuildableCurrent -
|
|
// RUN: echo "public func fn(_: String = #somethingYouveNeverHeardOf)" >> %t/UnbuildableCurrent.swiftinterface
|
|
//
|
|
// Next, modify a version of it so it looks like it was built with a different Swift compiler:
|
|
//
|
|
// RUN: sed -E -e 's|swift-compiler-version: (.*)|swift-compiler-version: NeoTokyoSwift 2000.42|' -e 's|UnbuildableCurrent|UnbuildableFuture|g' %t/UnbuildableCurrent.swiftinterface > %t/UnbuildableFuture.swiftinterface
|
|
//
|
|
// And finally, test:
|
|
//
|
|
// RUN: not %target-swift-frontend -typecheck %s -I %t -DCURRENT 2>&1 | %FileCheck -check-prefixes=ALL,CURRENT %s
|
|
// RUN: not %target-swift-frontend -typecheck %s -I %t -DFUTURE 2>&1 | %FileCheck -check-prefixes=ALL,FUTURE %s
|
|
//
|
|
// Test that we get the same results when typechecking the interface:
|
|
//
|
|
// RUN: not %target-swift-frontend -typecheck-module-from-interface %t/UnbuildableCurrent.swiftinterface 2>&1 | %FileCheck -check-prefixes=ALL,CURRENT-VERIFY %s
|
|
// RUN: not %target-swift-frontend -typecheck-module-from-interface %t/UnbuildableFuture.swiftinterface 2>&1 | %FileCheck -check-prefixes=ALL,FUTURE-VERIFY %s
|
|
|
|
// ALL: Unbuildable{{[^.]+}}.swiftinterface:{{[0-9]+}}:{{[0-9]+}}: error: no macro named 'somethingYouveNeverHeardOf'
