+// Since by its nature we may be coming from some other function to get
+// here, and we're using the stack frame for the containing function to
+// save/restore registers, we can't keep anything live in regs across
+// the eh_sjlj_setjmp(), else it will almost certainly have been tromped upon
+// when we get here from a longjmp(). We force everthing out of registers
+// except for our own input by listing the relevant registers in Defs. By
+// doing so, we also cause the prologue/epilogue code to actively preserve
+// all of the callee-saved resgisters, which is exactly what we want.
