Marc Rasi	bf18697b4f	parsing, typechecking, and SILGen for #assert ... `#assert` is a new static assertion statement that will let us write tests for the new constant evaluation infrastructure that we are working on. `#assert` works by lowering to a `Builtin.poundAssert` SIL instruction. The constant evaluation infrastructure will look for these SIL instructions, const-evaluate their conditions, and emit errors if the conditions are non-constant or false. This commit implements parsing, typechecking and SILGen for `#assert`.	2018-11-07 16:34:17 -08:00
Arnold Schwaighofer	b102c7f6b4	Parser/Sema/SILGen changes for @_dynamicReplacement(for:) ... Dynamic replacements are currently written in extensions as extension ExtendedType { @_dynamicReplacement(for: replacedFun()) func replacement() { } } The runtime implementation allows an implementation in the future where dynamic replacements are gather in a scope and can be dynamically enabled and disabled. For example: dynamic_extension_scope CollectionOfReplacements { extension ExtentedType { func replacedFun() {} } extension ExtentedType2 { func replacedFun() {} } } CollectionOfReplacements.enable() CollectionOfReplacements.disable()	2018-11-06 09:58:36 -08:00
