pessimising compiler definition
/pes'*-mi:z"ing k*m-pi:l"r/ (Antonym of "optimising compiler
") 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.
