Masikirwo angu ekushandisa programmer akatadza kana debugging assembler

My Application Programmer Instincts Yakundikana PaKugadzirisa Assembler

Kwemakore, nyika yangu yehunyanzvi yakavakwa pamusoro pezvikamu zvekubvisa. Semazuva ano anogadzira mapurogiramu, ndinogara munzvimbo yakagadzikana yemitauro yepamusoro-soro, nguva inotungamirirwa, uye masisitimu ane simba. A null pointer exception? Iyo stack trace inondinongedzera kumutsara une dambudziko. Kudeuka kwendangariro? Anonhonga marara anowanzozvibata ndisati ndambozviona. Iyi yekubvisa isimba guru, inotibvumira kuvaka masisitimu akaomarara senge Mewayz chikuva nekumhanya kunoshamisa. Asi munguva pfupi yapfuura, kunyura kwakadzika mune imwe legacy system kodhi - yakasvibira, isina kusvibiswa yakaunganidza - yakapwanya iyi nyaradzo. Mafungiro angu epamusoro-soro, akakudzwa kwemakore gumi, akanga asina kungobatsira; vakanga vachishingaira kunditsausa.

Basa racho raiita serakapusa zvakakwana: ziva kuti sei kukanganiswa kwehardware kwaikundikana zvishoma nezvishoma. Munyika yangu, izvi zvingasanganisira kutarisa faira regi, kutsvaga runhare rwekuita, kana kuseta nzvimbo yekuzorora. Pfungwa yangu yekutanga yaive yekutsvaga "basa." Ndakatarisa kodhi yeassembler, ndichitsvaga pateni inozivikanwa, yekupinda yakajeka uye yekubuda. Pane kudaro, ndakawana labyrinth yemirairo yekusvetuka ( JMP, JZ) iyo yakadzokera shure pachezvayo, ine data yakasanganiswa nekodhi.

• Kufungidzira kweAbstraction: Kutarisira pfungwa dzepamusoro-soro senge mabasa uye zvinhu zvichavepo pamwero wakaderera.
• Automatic Memory Management: Kukanganwa kuti ndangariro dzese dzinofanirwa kubatwa nekurondwa.
• Rich Debugging Data: Kuvimba nemazita ekufananidzira uye zviteshi zvisingawanikwe mukodhi yemuchina.
• Sequential Logic Flow: Kufunga maererano nezve maropu akarongeka uye mabhuroko anemiganho pachinzvimbo chekusvetuka-svetuka nemamureza.

Debugging assembler yakandidzidzisa kuti tsikidzi dzine njodzi hadzisi mukodhi, asi mufungidziro dzemugadziri wekuti kodhi inoshanda sei.
