A virtual address space is all of the addresses a process can generate / use. Further, all addresses used by processes are virtual addresses. +Kernels supporting other VA spaces, including 52 bit address spaces +are possible but less common. + The salient point is that even six bytes is far too large to fit in a four byte instruction. GDB is masking the pseudo instruction and showing what the effective addresses are.**
