Testing method: Mini test programs were written that run these syscalls for different arguments. Those programs were compiled (sometimes using cross-compilers) for the following architectures: * Intel 64-bit (little endian) (gcc) * Power pc 32-bit (big endian) (powerpc-linux-gnu-gcc) * Power pc 64-bit (big endian) (powerpc64-linux-gnu-gcc) * Mips 32-bit (little endian) (mipsel-linux-gnu-gcc) * Mips 64-bit (little endian) (mips64el-linux-gnuabi64-gcc) The corresponding native programs were executed with strace, without using QEMU, on Intel Core i7-4790K (x86_64) host. All applicable compiled programs were in turn executed with "-strace" through QEMU and the strace printing results obtained were the same ones gotten for native execution.
