Bochs magic breakpoint

[finarfin]

I'm trying to use the magic breakpoint feature of bochs.

So i added in my code the following instruction:

Code: Select all

asm("xchg bx, bx")

but when i try to compile it, i receive the following error:

Assembler message:
Error: Too many memory references for 'xchg'

Any idea?
Thanks

try:

Code: Select all

__asm__ __volatile__("xchg %bx, %bx");
