fs	IA-32 additional extra Segment Register
fsd	IA-32 additional extra Segment Register Descriptor
gdtd	IA-32 Global Descriptor Table Descriptor
gp	IA-64 Global Pointer, a synonym for r1
gp.nat	IA-64 Global Pointer Not-a-Thing bit, a synonym for r1.nat
gs	IA-32 additional extra Segment Register
gsd	IA-32 additional extra Segment Register Descriptor
iasp, esp	IA-32 Stack Pointer: iasp is two bytes wide, esp is four bytes wide with iasp as the two least signiﬁcant
	bytes. (The x86 mnemonic for the iasp register is “sp” but that conﬂicts with the IA-64 Stack Pointer of
	the same name, hence the name change for IA-32.)
