Abaphuhlisi be-V8 babonise i-decompiler yeWebAssembly

Abaphuhlisi be-injini ye-V8 JavaScript thaca into eluncedo wasm-decompile, ikuvumela ukuba udibanise eliphakathi lokumelwa kokubini WebAssembly kulwimi olungeyonyani olufundekayo olukhumbuza iJavaScript kunye noC. Ulwimi olucetywayo olucetywayo lulula kakhulu ukuluqonda kwaye lufaneleke ngakumbi ulwahlulo lwezandla kunokumelwa okubhaliweyo kweWebAssembly kwifomathi “.wat”, ekufutshane nolwimi lwendibano kuneelwimi ezikumgangatho ophezulu. Kule meko, ukuchithwa kubonisa ukumelwa kwe-Wasm ngokupheleleyo kangangoko kunokwenzeka.

I-Decompiler ifakiwe ibandakanyiwe kwikhithi yezixhobo WABT, ebonelela ngoguqulelo phakathi kokubini kunye nokubhaliweyo okubhaliweyo kweWebAssembly, kunye nokwahlulahlula, ukucubungula, ukuguqulwa kunye nokuqinisekiswa kweefayile ze-wam. I-WABT ikwaphuhlisa into eluncedo wam2c, evumela ukuba iifayile ze-wasm zidityaniswe zibe yikhowudi ye-C elinganayo enokuthi iqulunqwe ngumqokeleli we-C, kodwa ayahlukanga kakhulu ngokufundeka kombhalo "wat".

Umzekelo, umsebenzi wokuqala we-C ohlanganiswe kwi- wasm

uhlobo lwe-typedef {float x, y, z; } vec3;

ichaphaza lokudada (const vec3 *a, const vec3 *b) {
buyisela a->x * b->x +
a->y * b->y +
a->z * b->z;
}

iyakuchithwa yi-wasm-decompile into eluncedo ibe kulwimi-lobuxoki

umsebenzi ichaphaza (a:{ a:dada, b:dada, c:dada },
b:{ a:dada, b:dada, c:dada}):dada {
buyisela aa * ba + ab * bb + ac * bc
}

ngelixa uguqulelo kwifomati yokubhaliweyo ".wat" iza kujongeka ngolu hlobo

(func $dot (uhlobo 0) (param i32 i32) (isiphumo f32)
(f32.yongeza
(f32.yongeza
(f32.mul
(f32.umthwalo
(yasekhaya.fumana 0))
(f32.umthwalo
(yasekhaya.fumana 1)))
(f32.mul
(f32.load offset=4
(yasekhaya.fumana 0))
(f32.load offset=4
(yasekhaya.fumana 1))))
(f32.mul
(f32.load offset=8
(yasekhaya.fumana 0))
(f32.load offset=8
(yasekhaya.fumana 1)))))
