This patch adds support for a builtin function assert_configuration that is
replaced by constant progpagation by an appropriate value dependent on a compile
time setting. This replacement can also be disabled when serializing sil for a
library.
Using this mechanism we implement assertions that can be disabled (or whose
behavior changes) depending on compile time build settings (Debug, Release,
DisableReplacement).
In the standard library we can now write one assert function that uses this
builtin function to provide different compile time selectable runtime behavior.
Example
Assert.swift:
@transparent
func assert<T : LogicValue>(
condition: @auto_closure () -> T, message: StaticString = StaticString(),
// Do not supply these parameters explicitly; they will be filled in
// by the compiler and aren't even present when asserts are disabled
file: StaticString = __FILE__, line: UWord = __LINE__
) {
// Only in debug mode.
if _isDebug() {
assert(condition().getLogicValue(), message, file, line)
}
}
AssertCommon.swift:
@transparent
func _isDebug() -> Bool {
return Int32(Builtin.assert_configuration()) == 0;
}
