> Those cases would jump to a previously configured operation table for software helpers. What you want is called software interrupt or exception. MIPS and Alpha can do it for integer overflows. SPARC can do it for the two bottom tag bits of integers (to distinguish integers from pointers). I bet that if you only wait long enough, you will eventually see an architecture with both features. ;-) In the meantime we have to fall back to conditional jumps. :-/
