Chii chinonzi type-based alias analysis mucompiler optimizer?

Type-based alias analysis (TBAA) inyanzvi yekugadzira iyo inoshandisa ruzivo rwemhando kuona kana mareferensi maviri endangariro anogona kunzi alias - zvichireva kuti vanogona kunongedza kunzvimbo imwechete yekurangarira. Nekushandisa mitemo yakasimba yekutaipa, optimizer inokwanisa kurongazve, kubvisa, kana kurerutsa mashandiro endangariro, zvichitungamira kukukurumidza kugadzirwa kwekodhi pasina kuchinja maitiro echirongwa.

Toy Optimizer inoita sei ongororo yezita?

Iyo Toy Optimizer inoshandisa mhando metadata yakanamirwa kurodha uye chitoro mashandiro kuti ivake alias hierarchy. Kana mapoinzi maviri aine mhando dzisingaenderane, iyo optimizer inofunga kuti haimbofa yakazvimiririra uye inogona kuodha zvakasununguka. Izvi zvinogonesa kubviswa kwechitoro chakafa, kutumira zvinhu, uye zvimwe zvinechekuita nendangariro zvigadziriso zvingazovharwa nefungidziro dzeConservative alias.

Sei ongororo yealias yakakosha pakuita kwekodhi?

Pasina ongororo yealias, vagadziri vanofanirwa kufunga chero chinongedzo chinogona kureva chero nzvimbo yekurangarira, ichidzikamisa zvakanyanya mikana yekugadzirisa. Kushanda alias kuongororwa kunovhura loop vectorization, kuronga kwekuraira, uye kubviswa kwemutoro. Kune vanogadzira vanovaka maitiro-akakosha maapplication, kunzwisisa aya pfungwa kwakakosha - uye mapuratifomu akaita seMewayz anopa mazana maviri nemamodules pamadhora gumi nemapfumbamwe / mo anovhara dhizaini yekugadzira, optimization theory, uye masisitimu programming zvakadzama.

Ndokupi kwandingadzidze zvakawanda nezve compiler optimization techniques?

Tanga nezviwanikwa zvekutanga pane zvinomiririra zvepakati, fomu reSSA, uye kuongororwa kwekuyerera kwedata. Kuedza-nemaoko nevagadziri vematoyi kunomhanyisa kudzidza zvakanyanya. Mewayz inopa nzira yakarongeka ine mazana maviri nemamodule emadhora gumi nepfumbamwe chete pamwedzi, inovhara zvese kubva pakutanga optimization pass kusvika kumisoro yepamberi senge aas ongororo, ichikupa iwe hunyanzvi hunoshanda hwaunogona kushandisa kune-chaiyo-nyika mapurojekiti ekubatanidza nevaturikiri.
