-/// Inserts one nop instruction for each high level source statement for
-/// debugger usage.
-///
-/// Tools, such as a debugger, need to pause execution based on user input (i.e.
-/// breakpoint). In order to do this, one nop instruction is inserted before the
-/// first isa instruction of each high level source statement. Further, the
-/// debugger may replace nop instructions with trap instructions based on user
-/// input.
