• elf32_x86_64: ELF for x64-32, aka x32 — 32-bit x86-64 binaries

• elf_i386: ELF for i386 — 32-bit i386 binaries

• i386linux: a.out for i386

• i386pep: PE+ for x86-64 — Windows-format 64-bit binaries

• i386pe: PE for i386 — Windows-format 32-bit binaries

  Extra info: x32(elf32_x86_64) is a 32bit executable format, that will only run on x86_64. It is intended to use the benefits of x86 64bit mode, but be smaller than 64bit code. All data types (except time), are same as in 32bit mode.
