void CTraceEngine::trace ( class CAlphaCPU *  cpu,
u64  f,
u64  t,
bool  down,
bool  up,
const char *  x,
int  y

Trace function calling.

Parameters:
cpu Pointer to the CPU that jumps
f Address of the current instruction
t Address being jumped to
down This could be a function call
up This could be a return from a call
x Optional printf argument that describes what happens (eg "GO PAL %0x")
y Optional extra argument for the printf statement.
