hirOpt=cpf

HIR constant propagation and folding

hirOpt=cse

HIR common subexpression elimination

hirOpt=dce

HIR dead code elimination

lirOpt=cf

LIR constant folding

lirOpt=cpf

LIR constant propagation and folding

lirOpt=cse

LIR common subexpression elimination

lirOpt=dce

LIR dead code elimination

Each one is done only once, and if multiple items are specified, they will be performed in the order listed above.
