-    !! Prototype: int SafeFetch32 (int * adr, int ErrValue)
-    !! The "ld" at Fetch32 is potentially faulting instruction.
-    !! If the instruction traps the trap handler will arrange
-    !! for control to resume at Fetch32Resume.  
-    !! By convention with the trap handler we ensure there is a non-CTI
-    !! instruction in the trap shadow.

-    !! The reader might be tempted to move this service to .il.
-    !! Don't.  Sun's CC back-end reads and optimize code emitted 
-    !! by the .il "call", in some cases optimizing the code, completely eliding it,
-    !! or by moving the code from the "call site". 
-        
-     !! ASM better know we may use G6 for our own purposes
