; Tests to ensure that 64-bit displacement encoding works correctly without being RIP relative.
; x86-64 has two displacement encodings, one is RIP relative, one is 32-bit (signed) displacement only.
; modrm.mod = 0b00 && modrm.rm = 0b101: Means no SIB, but address mode is RIP + disp32.
; modrm.mod = 0b00 && modrm.rm = 0b100: Means SIB, but address mode is disp32.
;  - if SIB.base = 0b101 && SIB.index = 0b100. Which means no registers for base and index.
; Test disp32 by mapping a page at the limit of 2GB and read data from it. Also store and load.
; If we were accidentally using RIP relative, then it would be 2GB + <low test base address>, which won't be mapped.

; Test disp32 load.
