Siideynta LLVM 16.0 compiler suite

Ka dib lix bilood oo horumarin ah, sii deynta mashruuca LLVM 16.0 ayaa la soo bandhigay - qalab ku habboon GCC (compiers, optimizers and code-generators) kaas oo u diyaariya barnaamijyada koodka dhexdhexaadka ah ee RISC-u eg tilmaamaha farsamada (mashiin macmal ah oo hooseeya oo leh nidaamka tayaynta heerar badan). Pseudocode-ka la soo saaray waxaa loo rogi karaa iyadoo la isticmaalayo isku-duwaha JIT si toos ah tilmaamaha mashiinka wakhtiga fulinta barnaamijka.

Horumarka waaweyn ee Clang 16.0:

  • Heerka C ++/ObjC++ ee caadiga ah waa gnu ++17 (horey gnu ++14), taas oo macnaheedu yahay astaamaha C ++ 17 oo leh kordhinta GNU ayaa lagu taageerayaa default. Si aad u soo celiso dhaqankii hore, waxaad isticmaali kartaa "-std=gnu++14" doorashada.
  • Tilmaamo horumarsan oo la fuliyay oo la xidhiidha heerka C++20:

    • qabashada xirmooyinka habaysan ee hawlaha lambda,
    • Hawlwadeenka sinnaanta ee tibaaxaha,
    • Ikhtiyaarka ah in laga tago ereyga ereyga furaha ah xaaladaha qaarkood,
    • Bilawga wadarta saxda ah ee qawlka ("Aggr(val1, val2)").
  • Sifooyinka lagu qeexay heerka C++2b mustaqbalka waa la hirgeliyay:
    • Waa la oggol yahay in la dhigo summada dhammaadka tibaaxaha isku dhafan,
    • hawlwadeenka taagan (),
    • hawlwadeenka taagan[],
    • Waafaqsanaanta nooca char8_t waa la hubiyaa,
    • Kala duwanaanshaha xarfaha loo oggol yahay isticmaalka "\N{...}" waa la ballaariyay
    • Waxaa lagu daray awoodda isticmaalka doorsoomayaasha lagu dhawaaqay inay yihiin "static constexpr" ee hawlaha lagu sheegay constexpr.
  • Tilmaamaha lagu qeexay mustaqbalka C-standard C2x waa la fuliyay:
    • Si loo joojiyo digniinta "-Wunused-label", sifada "[[malaha_la isticmaalin]]" waa la ogol yahay in lagu dabaqo calaamadaha
    • Waa la oggol yahay in lagu dhejiyo calaamado meel kasta oo ka mid ah tibaaxaha isku dhafan,
    • Nooca iyo nooca_aan u dhigmin hawl wadeenada lagu daray,
    • Nooc cusub oo nullptr_t ah iyo nullptr joogto ah si loo qeexo tilmaameyaal aan waxba lahayn oo u rogi kara nooc kasta oo tilmaame ah oo ka dhigan kala duwanaanshiyaha NULL oo aan ku xidhnayn noocyada kala duwanaanshaha iyo faaruqa*.
    • Habka C2x, wacitaanka macro va_start oo wata tiro doorsooma oo dood ah (variadic) waa la oggol yahay.
  • Qaababka u hoggaansanaanta C99, C11, iyo C17, xulashooyinka caadiga ah "-Wimplicit-function-claration" iyo "-Wimplicit-int" hadda waxay soo saaraan qalad halkii digniinta.
  • Isticmaalka aan tooska ahayn ee "Void *" (tusaale "Vid func(void *p) {*p; }") ee qaabka C++ hadda waxay abuurtaa qalad, la mid ah ISO C++, GCC, ICC iyo MSVC.
  • Ku qeexida meelaha loo yaqaan 'bitfields' sida hawlgallada tilmaamaha (tusaale "__asm ​​​​{mov eax, s.bf}") ee ku jira xirmooyinka khadadka khadka ee qaabka Microsoft hadda waxay abuurtaa qalad.
  • Lagu daray ogaanshaha jiritaanka qaabab kala duwan iyo ururo leh magacyo isku mid ah qaybo kala duwan.
  • Awoodaha la xidhiidha taageerada OpenCL iyo OpenMP waa la balaariyay. Baadhitaannada la hagaajiyay ee qaababka C++ ee lagu isticmaalo doodaha kernel OpenCL. Taageerada xannibaadda safka oo la hagaajiyay ee AMDGPU. Sifada nounwind waxa si maldahan loogu daray dhammaan hawlaha. Taageerada la hagaajiyay ee hawlaha la dhisay.

Beddelay habka dejinta caadiga ah ee faylasha qaabeynta: clang waxay isku daydaa inay marka hore rarayso faylka - .cfg, haddii aan la helinna waxay isku daydaa inay ku shubto laba fayl .cfg iyo .cfg. Si aad u damiso rarka qaabeynta galka sida caadiga ah, calanka "--no-default-config" ayaa lagu daray.
  • Si loo hubiyo dhismayaal soo noqnoqon kara, waxa suurtagal ah in lagu beddelo qiimaha taariikhda iyo wakhtiga ee __DATE__, __TIME__ iyo __TIMESTAMP__ macros wakhtiga lagu cayimay doorsoomiyaha deegaanka SOURCE_DATE_EPOCH.
