This test verifies that analyzers without RunDespiteErrors are not
executed on a package containing type errors (see issue #54762).

We require go1.18 because the range of the `1 + ""` go/types error
changed then, and the new @diag marker is quite particular.

-- go.mod --
module example.com
go 1.12

-- a.go --
package a

func _() {
	// A type error.
	_ = 1 + "" //@diag(`1 + ""`, re"mismatched types|cannot convert")

	// A violation of an analyzer for which RunDespiteErrors=false:
	// no (simplifyrange, warning) diagnostic is produced; the diag
	// comment is merely illustrative.
	for _ = range "" { //diag("for _", "simplify range expression", )

	}
}
