Mushure memwedzi mitanhatu yebudiriro kuburitswa kweprojekiti -GCC-inoenderana maturusi (macompilers, optimizers uye macode jenareta), achigadzira zvirongwa kuva yepakati bitcode yeRISC-senge mirairo chaiyo (yakaderera-level virtual muchina ine akawanda-level optimization system). Iyo pseudocode inogadzirwa inogona kushandurwa uchishandisa JIT compiler kuita mirairo yemuchina zvakananga panguva yekuitwa kwechirongwa.
Shanduko yakakosha mukuburitswa kutsva yaive yekubatanidzwa kwe , kumberi kwemutauro weFortran. Flang inotsigira Fortran 2018, OpenMP 4.5 uye OpenACC 3.0, asi kusimudzira kweprojekiti hakusati kwapera uye kumberi kunogumira pakuparura kodhi uye kutarisa kuti ndeyechokwadi. Chizvarwa cheLLVM yepakati kodhi haisati yatsigirwa uye kugadzira mafaera anogoneka, canonical kodhi inogadzirwa uye inopfuudzwa kune yekunze Fortran compiler.
muClang 11.0:
- Yakawedzera kugona kudzoreredza iyo abstract syntax muti () yekodhi C ++ yakaputsika, inogona kushandiswa kubatsira kuongorora zvikanganiso uye inopa rumwe ruzivo kune zvekunze zvinoshandiswa senge clang-tidy uye clangd. Iyo ficha inogoneswa nekusarudzika kweC ++ kodhi uye inodzorwa kuburikidza ne "-Xclang -f[no-]kudzoreredza-ast" sarudzo.
- Yakawedzera nzira itsva dzekuongorora:
- "-Wpointer-to-int-cast" iboka reyambiro pamusoro pekukanda zvinongedzo kune nhamba yemhando int isinga tambire zvese zvinogoneka kukosha.
- "-Wunitialized-const-reference" - yambiro pamusoro pekupfuura zvisizvo zvisingaite mumaparamita ebasa anobvuma nharo dzereferensi ne "const" hunhu.

- Chengetedzo yemodule yatamiswa kubva pa/tmp kuenda ku ~/.cache dhairekitori. Kuti uwedzere, unogona kushandisa "-fmodules-cache-path=" mureza.
- Chimiro chemutauro weC chakagadziridzwa kubva pagnu11 kusvika gnu17.
- Yakawedzera rutsigiro rwekutanga rweGNU C yekuwedzera "Β» kuwedzera assembler insert. Kuwedzerwa kuchiri kuongororwa, asi kwete kugadziriswa nenzira ipi zvayo.
- Iwo masimba ane hukama neOpenCL uye CUDA rutsigiro akawedzerwa. Yakawedzera tsigiro yeOpenCL 2.0 block diagnostics uye yakaitwa nyowani OpenMP 5.0 maficha.
- Yakawedzera IndentExternBlock sarudzo ye clang-fomati yekushandisa yekumisikidza mukati mekunze "C" uye ekunze "C ++" zvidhinha.
- Iyo static analyzer yakavandudza kubata kwevakagarwa nhaka muC ++. Yakawedzera macheki matsva alpha.core.C11Lock uye alpha.fuchsia.Kiya kutarisa makiyi, alpha.security.cert.pos.34c kuona kushandiswa kusina kuchengeteka kwe putenv, webkit.NoUncountedMemberChecker uye webkit.RefCntblBaseVirtualDtor kuona maproblems asingaverengeki, alpha asingaverengeki .cplusplus .SmartPtr to check for null smart pointer dereference.
- In linter clang-tidy chikamu chikuru checheki itsva.
- Iyo clangd caching server (Clang Server) yakavandudza mashandiro uye yakawedzera hunyanzvi hwekuongorora.
chikuru LLVM 11.0:
- Iyo yekuvaka system yakachinjirwa kushandisa Python 3. Kana Python 3 isipo, zvinokwanisika kudzoreredza kushandisa Python 2.
- Iyo yekumberi ine muunganidzi weGo mutauro (llgo) haina kubatanidzwa kubva mukuburitswa, iyo inogona kugadziridzwa mune ramangwana.
- Iyo vector-function-abi-variant hunhu yawedzerwa kune yepakati inomiririra (IR) kutsanangura mepu pakati pe scalar uye vector mabasa ekuvector kufona. Kubva kullvm ::VectorType kune marudzi maviri akaparadzana mavheta llvm::FixedVectorType uye llvm::ScalableVectorType.
- Bazi rakavakirwa paudef kukosha uye kupfuudza undef kukosha kune akajairwa raibhurari mabasa anozivikanwa seasina kutsanangurwa maitiro. IN
memset/memcpy/memmove inobvumira kupfuura undef anonongedzera, asi kana parameter ine saizi iri zero. - LLJIT yakawedzera rutsigiro rwekuita static yekutanga kuburikidza neLLJIT ::kutanga uye LLJIT ::deinitialize nzira. Iko kugona kuwedzera static maraibhurari kuJITDylib uchishandisa iyo StaticLibraryDefinitionGenerator kirasi yakaitwa. Yakawedzerwa C API ye (API yekuvaka JIT compilers).
- Tsigiro yeCortex-A64, Cortex-A34, Cortex-A77 uye Cortex-X78 processors yakawedzerwa kuseri kweiyo AArch1 architecture.

Yakawedzerwa dziviriro pakurwiswa (Load Value Injection), uye zvakare inoshandisa yakajairwa Kuteedzera Kuuraya Side Effect Suppression mechanism yekuvharisa kurwiswa kunokonzerwa nekufungidzira kuuraya maoperation paCPU.
- Mumashure ekuvakwa kweSystemZ, tsigiro yeMemorySanitizer uye LeakSanitizer yakawedzerwa.
- Yakawedzera tsigiro yemusoro faira ine masvomhu anoramba aripo kuLibc++ .
- LLD linker kugona. Yakavandudzwa rutsigiro rweiyo ELF fomati, kusanganisira yakawedzerwa sarudzo "--lto-emit-asm", "--lto-whole-program-visibility", "-print-archive-stats", "-shuffle-sections", " -thinlto- single-module", "-yakasiyana", "-rosegment", "-threads = N". Yakawedzerwa "--time-trace" sarudzo yekuchengetedza iyo faira, iyo inogona kuongororwa kuburikidza ne chrome://tracing interface muChrome.
