// If you turn off deduplicate diagnostics (which rustc turns on by default but
|
|
// compiletest turns off when it runs ui tests), then the errors are
|
|
// (unfortunately) repeated here because the checking is done as we read in the
|
|
// errors, and currently that happens two or three different times, depending on
|
|
// compiler flags.
|
|
//
|
|
// The test is much cleaner if we deduplicate, though.
