Generallooking for unoptimised C codes Pin

helo friends,

I am looking for unoptimised C codes that considerably reduces the performance of the system.

I am looking for some of the cases (like,
inline functions,constant propagation,constant folding,faster for loops,loop fusion,loop jamming,table lookup,arrays,induction variable,commom sub expressions etc) by which when a programmer misuses them(above mentioned cases) in turn affect the performance of the system.

Example for Common Sub Expression Elimination.
(unoptimised code)
t1=x+y+1;
t2=x+y;

Instead declare a temporary variable say temp.calculate temp=x+y and then use in these instructions.so,introducing temp becomes my optimised code avoiding calculations.

temp=x+y;
t1=temp+1;
t2=temp;

By doing this i am avoiding the calculation thats happening twice.if such calculations are in for loop it really affects the performance.By doing this Common sub expression elimination we gain performance.

I am looking for such unoptimised codes in the cases mentioned above.

If anyone gets please do send me the details.
