#------------------------------------------------------------------------------ # mach file description # # Since Java bytecode and Mach-O fat-files have the same magic number the test # must be preformed in the same "magic" sequence to get both right. The long # at offset 4 in a fat file tells the number of architectures. The short at # offset 4 in a Java bytecode file is the compiler minor version and the # short at offset 6 is the compiler major version. Since the minor version is # never to be non-zero then the hack of testing for the number of architectures # to be less that the maximum short is done here. # 0 belong 0xcafebabe >4 belong 0x0003002d Java bytecode >4 belong 1 Mach-O fat file with 1 architecture >4 belong >1 >>4 belong <0xffff Mach-O fat file with %ld architectures # 0 lelong 0xfeedface Mach-O >12 lelong 1 object >12 lelong 2 executable >12 lelong 3 fixed virtual memory shared library >12 lelong 4 core >12 lelong 5 preload executable >12 lelong 6 dynamically linked shared library >12 lelong 7 dynamic linker >12 lelong 8 bundle >12 lelong 9 dynamically linked shared library stub >12 lelong >9 >>12 lelong x filetype=%ld >4 lelong <0 >>4 lelong x architecture=%ld >4 lelong 1 vax >4 lelong 2 romp >4 lelong 3 architecture=3 >4 lelong 4 ns32032 >4 lelong 5 ns32332 >4 lelong 6 m68k >4 lelong 7 i386 >4 lelong 8 mips >4 lelong 9 ns32532 >4 lelong 10 architecture=10 >4 lelong 11 hppa >4 lelong 12 acorn >4 lelong 13 m88k >4 lelong 14 sparc >4 lelong 15 i860-big >4 lelong 16 i860 >4 lelong 17 rs6000 >4 lelong 18 ppc # This is for INTERIM_PPC64 >4 lelong 19 ppc64 >4 lelong >19 >>4 lelong x architecture=%ld # 0 belong 0xfeedface Mach-O >12 belong 1 object >12 belong 2 executable >12 belong 3 fixed virtual memory shared library >12 belong 4 core >12 belong 5 preload executable >12 belong 6 dynamically linked shared library >12 belong 7 dynamic linker >12 belong 8 bundle >12 belong 9 dynamically linked shared library stub >12 belong >9 >>12 belong x filetype=%ld >4 belong <0 >>4 belong x architecture=%ld >4 belong 1 vax >4 belong 2 romp >4 belong 3 architecture=3 >4 belong 4 ns32032 >4 belong 5 ns32332 >4 belong 6 m68k >4 belong 7 i386 >4 belong 8 mips >4 belong 9 ns32532 >4 belong 10 architecture=10 >4 belong 11 hppa >4 belong 12 acorn >4 belong 13 m88k >4 belong 14 sparc >4 belong 15 i860-big >4 belong 16 i860 >4 belong 17 rs6000 >4 belong 18 ppc # This is for INTERIM_PPC64 >4 belong 19 ppc64 >4 belong >19 >>4 belong x architecture=%ld
