Pushing the registers onto the stack (x64).

[Dave]

Is there a way to either directly get the contents of the x64 registers or
push them onto the stack (and of course pop the same) w/o having to use
MASM64?

For example, in VC++ x86:

__asm pushad;
DoSomething();
__asm popad;

or

DWORD r0,r1,r2,r3,r4,r5,r6;
__asm
{
mov r0,eax;
mov r1,ebx;
mov r2,ecx;
mov r3,edx;
mov r4,esi;
mov r5,edi;
mov r6,ebp;
}
mystack.push(r0);
mystack.push(r1);
mystack.push(r2);
mystack.push(r3);
mystack.push(r4);
mystack.push(r5);
mystack.push(r6);
DoSomething();

IA64 at least has __getReg()... I'd hate to have to dig into MASM64 for
this.

GetThreadContext() does't return them all (volatile registers are not
accurate), even if the thread is suspended prior.

TIA,

It's too OS and compiler specific to ask in clc++. Try a newsgroup related
to your OS/Compiler.
