| /* | |
| * 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. | |
