MOV (EAX, Moffs32) - Latency

Operands

Operand 1 (w): Register (EAX)
Operand 2 (r): Memory

Latency operand 2 → 1: ≤1

Latency operand 2 → 1 (memory): ≤1

Latency operand 2 → 1: ≤1

Experiment 1

Instruction: MOV EAX, dword ptr [0xffffa359824a5000]
Chain instructions: MOVSX R12, EAX;MOVSX R12, R12d;MOVSX R12, R12d;MOVSX R12, R12d;mov [R14], R12D
Chain latency: ≥5

Code:

   0:	a1 00 50 4a 82 59 a3 	movabs eax,ds:0xffffa359824a5000
   7:	ff ff 
   9:	4c 63 e0             	movsxd r12,eax
   c:	4d 63 e4             	movsxd r12,r12d
   f:	4d 63 e4             	movsxd r12,r12d
  12:	4d 63 e4             	movsxd r12,r12d
