}

The jitdump header.

Fields

magic: [u8; 4]

Four bytes tagging the file type and declaring the endianness of this file. When interpreted as a u32 in the correct endian, this is 0x4A695444. Represents the string “JiTD” in ASCII form.

version: u32

The format version. It is currently set to 1.

total_size: u32

The size in bytes of file header.

elf_machine_arch: u32

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

pid: u32

The process ID of the JIT runtime process.

timestamp: u64

The timestamp of when the file was created.

flags: u64

A bitmask of flags.
