Example 36 with InstalledCode

use of jdk.vm.ci.code.InstalledCode in project graal by oracle.

the class GraalCompilerTest method getCode.

/**
 * Gets installed code for a given method and graph, compiling it first if necessary.
 *
 * @param installedCodeOwner the method the compiled code will be associated with when installed
 * @param graph the graph to be compiled. If null, a graph will be obtained from
 *            {@code installedCodeOwner} via {@link #parseForCompile(ResolvedJavaMethod)}.
 * @param forceCompile specifies whether to ignore any previous code cached for the (method,
 *            key) pair
 * @param installAsDefault specifies whether to install as the default implementation
 * @param options the options that will be used in {@link #parseForCompile(ResolvedJavaMethod)}
