In peephole.c I noticed some expression optimizations:
/* not a is b --> a is not b
not a in b --> a not in b
not a is not b --> a is b
not a not in b --> a in b
*/
So, it seems that an operation can be changed to another one which is logically
equivalent.
Could it be applyable to other operations as well? So, if I wrote:
c = not(a < b)
the compiler and/or peephole optimizer can generate bytecodes instructions
which, instead, execute the following operation:
c = a >= b
Is it right?
Thanks a lot
Cesare
