Rui Ueyama, LLVM lld ja chibicc kompilaatori autor, tutvustas uue k\u00f5rge j\u00f5udlusega linker'i Mold esimest stabiilset v\u00e4ljaannet, mis \u00fcletab GNU gold ja LLVM lld objektifailide sidumise kiiruselt. Projekti peetakse t\u00f6\u00f6ks valmis ja seda saab kasutada kiiremana, et asendada GNU linkeri Linuxi s\u00fcsteemides. J\u00e4rgmise suure v\u00e4ljaande plaanidesse kuulub macOS toe valmimine, p\u00e4rast mida hakatakse Moldi kohandama Windowsile. <\/p>\n

Mold on kirjutatud C++ (C++20) keeles ja jaotatakse AGPLv3 litsentsi alusel, mis on \u00fchilduv GPLv3-ga, kuid ei ole \u00fchilduv GPLv2-ga, kuna n\u00f5uab muudatuste avalikustamist v\u00f5rgu teenuste arendamisel. Selline valik on seletatav sooviga saada arenduse rahastamist \u2014 autor on valmis m\u00fc\u00fcma koodi \u00f5igusi, et litsentseerida see uuesti m\u00f5ne lubava litsentsi, n\u00e4iteks MIT, alla v\u00f5i pakkuda eraldi kommertslitsentsi neile, keda AGPL ei rahulda. <\/p>\n

Mold toetab k\u00f5iki GNU linkija v\u00f5imalusi ning eristub v\u00e4ga k\u00f5rge tootlikkuse poolest \u2014 linkimine toimub kiirusel, mis on vaid kaks korda aeglasem kui failide kopeerimine cp utiliidiga. N\u00e4iteks Chrome 96 (koodisuurusega 1.89 GB) kompileerimise aega t\u00e4iendavate failide linkimiseks debuginfo-ga 8-keralises arvutis kasutades GNU gold kulub 53 sekundit, LLVM lld \u2014 11.7 sekundit, samas kui Mold vajab vaid 2.2 sekundit (26 korda kiiremini kui GNU gold). Clang 13 (3.18 GB) linkimisel on GNU gold vaja 64 sekundit, LLVM lld \u2014 5.8 sekundit ja Mold \u2014 2.9 sekundit. Firefox 89 (1.64 GB) linkimisel kulub GNU gold 32.9 sekundit, LLVM lld \u2014 6.8 sekundit, samas kui Mold \u2014 1.4 sekundit.

\"Esimene<\/center> <\/p>\n

Sidumise aja l\u00fchenemine v\u00f5imaldab oluliselt parandada suurte projektide arendamise mugavust, v\u00e4hendades ooteaega t\u00e4itmise protsessis, kui debugeerimiseks ja muudatuste testimiseks valmistatakse ette k\u00e4ivitatavaid faile. Moldi loomise t\u00f5ukeks oli frustratsioon vajadusest oodata sidumise l\u00f5petamist p\u00e4rast iga koodimuudatust, samuti olemasolevate sidurite madal efektiivsus mitme tuuma s\u00fcsteemides ning soov proovida t\u00e4iesti erinevat sidumisarhitektuuri, ilma et oleks vaja tugineda liigsetele mudelitele, nagu inkrementaalne sidumine. <\/p>\n

Moldi t\u00e4idetud faili k\u00f5rge j\u00f5udlus saavutatakse kasutades kiiremaid algoritme, aktiivset operatsioonide paralleelset t\u00f6\u00f6tlemist saadaval CPU tuumade vahel ning t\u00f5husamate andmestruktuuride rakendamisega. N\u00e4iteks on Moldis rakendatud tehnika intensiivsete arvutuste samaaegseks t\u00e4itmiseks failide kopeerimisega, objektifailide proaktiivne laadimine m\u00e4llu, kiirete rippmehanismide kasutamine s\u00fcmbolite lahendamisel, liikumistabelite skaneerimine eraldi l\u00f5imes ning kordsete osade dedupikatsioon erinevates failides.
