Example 1 with CompilerConfiguration

use of org.graalvm.compiler.phases.tiers.CompilerConfiguration in project graal by oracle.

the class CompilerConfigurationFactory method selectFactory.

/**
 * Selects and instantiates a {@link CompilerConfigurationFactory}. The selection algorithm is
 * as follows: if {@code name} is non-null, then select the factory with the same name else if
 * {@code Options.CompilerConfiguration.getValue()} is non-null then select the factory whose
 * name matches the value else select the factory with the highest
 * {@link #autoSelectionPriority} value.
 *
 * @param name the name of the compiler configuration to select (optional)
