Hello,

The patch adds a check that warns for relational comparison of boolean expressions with literals 1 and 0.
example:

bool x;
int i,e,y;

if(x > 1){}
if(!i < 0){}
if(1 > (e<y)){}

generates warning:
"relational comparison of boolean expression against literal value '1' or '0' "

see test files bool-compare.c and bool-compare.cpp for more details.


Best regards,
Per
