My question is about Intel 64 and IA-32 software developer's manual 3A. It says:
6.14.3 IRET in IA-32e Mode
The size of the pop is determined by the address size of the instruction. The SS/ESP/RSP size adjustment is determined by
the stack size.
IRET pops SS:RSP unconditionally off the interrupt stack frame only when it is
executed in 64-bit mode. In compatibility mode, IRET pops SS:RSP off the stack only
if there is a CPL change.
---------------------------------------
The size of pop is determined by the address size or by the operand size? SS/ESP/RSP or SP/ESP/RSP?
In compatibility mode, IRET pops SS:RSP off the stack or SS:ESP(SS:SP)?
Is there any forum to discuss Intel data sheets and documents?
