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. */ #ifndef _JVMTI_CMLR_H_ #define _JVMTI_CMLR_H_ enum { JVMTI_CMLR_MAJOR_VERSION_1 = 0x00000001, JVMTI_CMLR_MINOR_VERSION_0 = 0x00000000, JVMTI_CMLR_MAJOR_VERSION = 0x00000001, JVMTI_CMLR_MINOR_VERSION = 0x00000000 /* * This comment is for the "JDK import from HotSpot" sanity check: * version: 1.0.0 */ }; typedef enum { JVMTI_CMLR_DUMMY = 1, JVMTI_CMLR_INLINE_INFO = 2 } jvmtiCMLRKind; /* * Record that represents arbitrary information passed through JVMTI * CompiledMethodLoadEvent void pointer. */ typedef struct _jvmtiCompiledMethodLoadRecordHeader { jvmtiCMLRKind kind; /* id for the kind of info passed in the record */ jint majorinfoversion; /* major and minor info version values.
