Example 4 with JavaField

use of jdk.vm.ci.meta.JavaField in project graal by oracle.

the class BytecodeParser method tryFastInlineAccessor.

/**
 * Tries to inline {@code targetMethod} if it is an instance field accessor. This avoids the
 * overhead of creating and using a nested {@link BytecodeParser} object.
 */
