Fixed-sized header for each jitdump file

Fields

magic: u32

uint32_t magic: a magic number tagging the file type. The value is 4-byte long and represents the string “JiTD” in ASCII form. It is 0x4A695444 or 0x4454694a depending on the endianness. The field can be used to detect the endianness of the file

version: u32

uint32_t version: a 4-byte value representing the format version. It is currently set to 2

size: u32

uint32_t total_size: size in bytes of file header

e_machine: u32

uint32_t elf_mach: ELF architecture encoding (ELF e_machine value as specified in /usr/include/elf.h)

pad1: u32

uint32_t pad1: padding. Reserved for future use

pid: u32

uint32_t pid: JIT runtime process identification (OS specific)

timestamp: u64

uint64_t timestamp: timestamp of when the file was created

flags: u64

uint64_t flags: a bitmask of flags
