/*
 * 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.
