Inizia da Python/perf_jit_trampoline.c, intorno alla riga 375, e riproduci la build riscv64 a partire dal fallimento del buildbot collegato. Confronta l'ultimo commit riuscito e il primo commit fallito, quindi esamina gh-121328, gh-121336 e gh-121387; il lavoro è completato quando la build riscv64 termina senza l'errore unsupported-target.
