Den f\u00f6rsta betydande utg\u00e5van av Blink-projektet har publicerats, som utvecklar en emulator f\u00f6r x86-64-processorer, vilket m\u00f6jligg\u00f6r k\u00f6rning av b\u00e5de statiskt och dynamiskt sammanst\u00e4llda Linux-applikationer i en virtuell maskin med en emulerad processor. Med Blink kan program som har sammanst\u00e4llts f\u00f6r x86-64-arkitekturen k\u00f6ras p\u00e5 andra POSIX-kompatibla operativsystem (macOS, FreeBSD, NetBSD, OpenBSD, Cygwin) och p\u00e5 h\u00e5rdvara med en annan arkitektur (x86, ARM, RISC-V, MIPS, PowerPC, s390x). Koden f\u00f6r projektet \u00e4r skriven i C-spr\u00e5ket (ANSI C11) och distribueras under ISC-licensen. Endast libc (POSIX.1-2017) kr\u00e4vs som beroende. <\/p>\n

Blink har en funktionalitet liknande qemu-x86_64, men skiljer sig fr\u00e5n QEMU genom en mer kompakt design och en signifikant prestandaf\u00f6rb\u00e4ttring. Till exempel \u00e4r den k\u00f6rbara filen f\u00f6r Blink endast 221 KB (i en nedskuren version - 115 KB) ist\u00e4llet f\u00f6r 4 MB f\u00f6r qemu-x86_64, och i vissa tester, s\u00e5som k\u00f6rning i GCC-emulatorn och utf\u00f6rande av matematiska operationer, \u00f6vertr\u00e4ffar den QEMU med cirka dubbelt s\u00e5 mycket. <\/p>\n

F\u00f6r att s\u00e4kerst\u00e4lla h\u00f6g prestanda anv\u00e4nds en JIT-kompilator som omvandlar k\u00e4llinstruktioner i realtid till maskinkod f\u00f6r m\u00e5ldatorn. Direkt k\u00f6rning av exekverbara filer i formaten ELF, PE (Portable Executables) och bin (Flat executable), som har sammanst\u00e4llts med standard C-bibliotek som Cosmopolitan, Glibc och Musl, st\u00f6ds. Inbyggt st\u00f6d f\u00f6r 180 systemanrop fr\u00e5n Linux och emulering av ungef\u00e4r 600 x86-processorinstruktioner har implementerats, vilka t\u00e4cker instruktioner fr\u00e5n i8086, i386, SSE2, x86_64, SSE3, SSSE3, CLMUL, POPCNT, ADX, BMI2 (MULX, PDEP, PEXT), X87, RDRND, RDSEED och RDTSCP. <\/p>\n

Dessutom utvecklas ett verktyg, blinkenlights, baserat p\u00e5 Blink, som erbjuder ett gr\u00e4nssnitt f\u00f6r att visualisera programmets k\u00f6rning och analysera minnesinneh\u00e5ll. Verktyget kan anv\u00e4ndas som en debugger som st\u00f6der omv\u00e4nd avl\u00e4sning (Reverse-Debugging) och g\u00f6r det m\u00f6jligt att g\u00e5 tillbaka i exekveringshistorien och \u00e5terv\u00e4nda till tidigare utf\u00f6rda punkter. Projektet utvecklas av skaparen av s\u00e5dana utvecklingar som C-biblioteket Cosmopolitan, porteringen av isoleringsmekanismen pledge f\u00f6r Linux och systemet f\u00f6r universella exekverbara filer Redbean.
