Saabunud on Python 3.13.0a6 programmeerimiskeele alfa v\u00e4ljaanne, milles on esmakordselt sisse viidud 3.13 haru, mille alusel t\u00f6\u00f6tatakse s\u00fcgisese stabiilse versiooni Python 3.14 v\u00e4ljaande kallal. Uue JIT-kompileerimise eksperimentaalne teostus v\u00f5imaldab saavutada olulisi tulemuslikkuse paranemisi. JIT-i aktiveerimiseks CPythonis on lisatud koostamisvalik «—enable-experimental-jit». JIT-i toimimiseks on vajalik LLVM installimine kui t\u00e4iendav s\u00f5ltuvus. <\/p>\n

JIT-i masinkoodi t\u00f5lkeprotsess p\u00f5hineb arhitektuuril «Copy-and-Patch», kus LLVM abil koostatakse ELF formaadis objekti fail, mis sisaldab bytecode'i k\u00e4skude andmeid ja vajalikku teavet andmete asendamiseks. JIT asendab interpreteerimise k\u00e4igus genereeritud bytecode'i k\u00e4sud nende masinkoodi ekvivalentidega, sisestades samal ajal vajalikud arvutuste jaoks vajalikud andmed (JIT kopeerib valmis mudelid juba kompileeritud funktsioonidest ja asendab nendes vajalikud v\u00e4\u00e4rtused, nagu argumendid ja konstantid). <\/p>\n

Pakutud JIT paistab silma v\u00e4ga k\u00f5rge koodigeneratsiooni kiirusena, lihtsuse poolest hooldamisel ja t\u00e4ieliku integreerimisega t\u00f5lgiga. V\u00f5rreldes WebAssembly kompileerimisega (Liftoff) genereerib uus JIT koodi viis korda kiiremini ja loodud kood t\u00f6\u00f6tab 50% kiiremini. Traditsioonilise JIT-t\u00f6\u00f6riistakomplekti LLVM-ga v\u00f5rreldes tagab CPythonis lisatud JIT 100 korda kiirema koodigeneratsiooni ja 15% kiirema genereeritud koodi.
