Large Edit:

according to the Intel Manual Volume 3A, Chapter 6, Section 12.1, Figure 6-4:
if the privilege level doesn't change (meaning the exception happened in CPL 0) the stack is:

so the parameter definitions should be according to the cdecl calling convention

Code: Select all

(unsigned int err, unsigned int eip, unsigned int cs, unsigned int eflags)
and
(unsigned int eip, unsigned int cs, unsigned int eflags)

not

Code: Select all

(unsigned int cs,unsigned int err,  unsigned int eip, unsigned int eflags)
and
(unsigned int cs, unsigned int eip, unsigned int eflags)

and in the event of a privilege level change (CPL 3 and interrupt's DPL is 0) the handler's stack is:

and the interrupted procedure's stack is left unchanged
