Port to the 64-bit ARM architecture with the new version 8 64-bit instruction set (called AArch64), for processes such as the Applied Micro X-Gene, AMD Seattle and Cavium ThunderX. LITTLE_ENDIAN : BIG_ENDIAN); } This code assigns the value 0001h to a 16-bit integer. The function at address 00671618 in IDA pro is parses the WSSE security token header. When the bit order is the default bit order, growing bit offsets simply correspond to going into successive (growing) addresses in memory. After much toil in trying to build a GCC cross-compiler and search the internet for solution, I found binaries for a big-endian cross compiler (armeb) on linaro. With arm dominating the processor world and x86 covering desktops, laptops, and servers, the pci(e) conventions, etc, we really do live in a little endian world like it or not. Intel x86 processor is little-endian, so most personal computers are little-endian. Arm has supported bi-endianness since ARMv4, though most platforms these days use Arm in little-endian endian configuration. Now that we have all the 4 bytes of the number, we need to concatenate it in reverse order.
