55 The record header is specified in order as follows:
56 * uint32_t id : a value identifying the record type (see below)
57 * uint32_t total_size: the size in bytes of the record including the header.
58 * uint64_t timestamp : a timestamp of when the record was created.
60 The following record types are defined:
61 * Value 0 : JIT_CODE_LOAD : record describing a jitted function
62 * Value 1 : JIT_CODE_MOVE : record describing an already jitted function which is moved
63 * Value 2 : JIT_CODE_DEBUG_INFO: record describing the debug information for a jitted function
