Intel i386 is little endian. Motorola Powerpc is big endian.
I copied it from here: http://asm.inightmare.org/opcodelst/index.php?op=BSWAP I think the author was confused. I am always confused, too, because the big/little endian thing is named wrong IMO. In human readable numbers, reading from left to right, big numbers (MSB) come first and little numbers (LSB) last. In essense it is a "little endian" notation as it ends with little numbers. Motorola 68000 and others use the same logic (MSB - LSB) but for some reason it is called " big endian" while Intel which has it upside down, is called "little endian". IIRC the names refer to memory layout, how those registers are written to memory. Anyway, I am confused but it does not matter because there are functions made by someone else and I don't need to think of the details. :) Regards, Juha _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
