com.oracle.graal.api.directives.test.BlackholeDirectiveTest

public class BlackholeDirectiveTest
extends GraalCompilerTest

Tests for GraalDirectives.blackhole(boolean). There are two snippets for each kind:

• blackhole<Kind>Snippet verifies that dead code elimination is prevented by the blackhole directive.
• <kind>Snippet verifies that dead code elimination does happen if the blackhole directive is not there.
