74 instrumented memory reference into the hash table.
75 (maybe_instrument_assignment): Renamed instrument_assignment into
76 this, and change it to advance the iterator when instrumentation
77 actually happened and return true in that case. This makes it
78 homogeneous with maybe_instrument_assignment, and thus give a
79 chance to callers to be more 'regular'.
80 (transform_statements): Clear the memory reference hash table
81 whenever we enter a new BB, when we cross a function call, or when
82 we are done transforming statements. Use
83 maybe_instrument_assignment instead of instrumentation. No more
84 need to special case maybe_instrument_assignment and advance the
85 iterator after calling it; it's now handled just like
86 maybe_instrument_call. Update comment.
