Izi zidzapangitsa kuti ma regista onse otsekedwa asungidwe mopanda kufunikira, ndipo zosokoneza zidzayatsidwa ngakhale epilogue ya wothandizira wosokoneza panopa asanayambe, zomwe zingayambitse kulephera kwa code.
Const zinthu zomwe sizili mu memory ya pulogalamu (XCS-2408) Kwa ma avrxmega3 ndi ma avertins ma projekiti osadziwika bwino zinthu zimayikidwa mu kukumbukira kwa data, ngakhale chenjezo likuwonetsa kuti zayikidwa mu kukumbukira pulogalamu. Izi sizikhudza zida zomwe zilibe kukumbukira pulogalamu yojambulidwa mu malo okumbukira deta, komanso sizikhudza chinthu chilichonse chomwe chakhazikitsidwa.
Kutulutsa koyipa kokhala ndi njira yolakwika ya DFP (XCS-2376) Ngati wopangayo apemphedwa ndi njira yolakwika ya DFP ndi 'spec' file ilipo pa chipangizo chomwe chasankhidwa, wophatikiza sakunena zapaketi yapachipangizo yomwe ikusowa ndipo m'malo mwake amasankha 'spec' file, zomwe zitha kubweretsa kutulutsa kosavomerezeka. The 'spec' filemwina sizingakhale zatsopano ndi ma DFP omwe adagawidwa ndipo adapangidwa kuti agwiritsidwe ntchito poyesa makina amkati okha.
Kulumikizana kwa Memory sikunazindikirike (XCS-1966) Wopangayo sazindikira kukumbukira kukumbukira zinthu zomwe zidapangidwa kwathunthu ku adilesi (kudzera pa ()) ndi zinthu zina pogwiritsa ntchito gawo () chofotokozera komanso zomwe zimalumikizidwa ndi adilesi yomweyo.
Kulephera ndi ntchito za library ndi _meme (XCS-1763) Zotchedwa limbic float function ndi mkangano mu _memo adilesi malo akhoza kulephera. Zindikirani kuti machitidwe a laibulale amayitanidwa kuchokera kwa ena ogwira ntchito C, kotero, mwachitsanzoample, code yotsatirayi ikukhudzidwa: kubwerera regFloatVar > memxFloatVar;
Kukhazikitsa kwa limbic zochepa (AVRTC-731) Pazinthu za ATTiny4/5/9/10/20/40, kukhazikitsidwa kwa library ya C / Math mu limbic ndikochepa kapena kulibe.
Zolepheretsa kukumbukira pulogalamu (AVRTC-732) Zithunzi zokumbukira pulogalamu yopitilira 128 kb zimathandizidwa ndi zida; komabe, pali zochitika zodziwika za kuchotsa mimba kwa linker popanda kumasuka komanso popanda uthenga wolakwika wothandiza m'malo mopanga ma stubs ofunikira pamene njira -relax ikugwiritsidwa ntchito.
Tchulani malire a malo (AVRTC-733) Malo otchulidwa adiresi amathandizidwa ndi toolchain, malinga ndi zofooka zomwe zatchulidwa mu gawo lachilolezo cha ogwiritsira Ntchito Zoyenerera Zamtundu Wapadera.
