+ * This header file defines the data structures sent by the VM
+ * through the JVMTI CompiledMethodLoad callback function via the
+ * "void * compile_info" parameter. The memory pointed to by the
+ * compile_info parameter may not be referenced after returning from
+ * the CompiledMethodLoad callback. These are VM implementation
+ * specific data structures that may evolve in future releases. A
+ * JVMTI agent should interpret a non-NULL compile_info as a pointer
+ * to a region of memory containing a list of records. In a typical
+ * usage scenario, a JVMTI agent would cast each record to a
+ * jvmtiCompiledMethodLoadRecordHeader, a struct that represents
+ * arbitrary information. This struct contains a kind field to indicate
+ * the kind of information being passed, and a pointer to the next
+ * record. If the kind field indicates inlining information, then the
+ * agent would cast the record to a jvmtiCompiledMethodLoadInlineRecord.
+ * This record contains an array of PCStackInfo structs, which indicate
+ * for every pc address what are the methods on the invocation stack.
+ * The "methods" and "bcis" fields in each PCStackInfo struct specify a
+ * 1-1 mapping between these inlined methods and their bytecode indices.
+ * This can be used to derive the proper source lines of the inlined
+ * methods.
