/pes'*-mi:z"ing k*m-pi:l"r/ (Antonym of "optimisingcompiler") A compiler that produces object code that is

worse than the straightforward or obvious hand translation.

The implication is that the compiler is actually trying to

optimise the program, but through excessive cleverness is

doing the opposite. A few pessimizing compilers have been

written on purpose, however, as pranks or burlesques.
