/*

|
* 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.
