@chrchr-github I think there is some more low hanging fruit for this checker. Here is code from the Misra C example suite:

void R_2_2(uint16_t v)
{
   v >> 3;
}

A constStatement warning would be nice, wouldn't it? :-)

Here's what I get:

test.cpp:3:7: warning: inconclusive: Found suspicious operator '>>', result is not used. [constStatement]
    v >> 3;
      ^
