Comment on Why can't code be uncompiled?
UnRelatedBurner@sh.itjust.works 8 months agofollow up, will it be easier to read this context-less source code or stay at assembly? If for example you’d like to modify a closed source app
Probably depends on how comfortable you are at reading assembly instructions for your specific CPU, but I think generally the contextless source code is probably preferable. Either way you’ve got a headache of an investigation in front of you though.
here’s an example of what it might look like with either option
oh wow, I now respect pirates even more. No wonder there are only like 3 guys that can and will do this.
If you decompile you need such an understanding of the language. I could see someone looking at this and going “oh yeah that compares cases”, but then die of old age before finishing the sentance.
And if you don’t decompile you are coding assembly.

Like many things, it’s very fact-intensive, varying in different circumstances. As others have noted, the abilities of the person undertaking the decompilation will influence the decision. But so will strategy: the overall goal can drive how decompilation is approached.
For example, suppose you’re working for an airline company and need to rewrite some software used on an ancient IBM System/360 machine and was written in the COBOL language, for which no source code is available and you cannot find many people who even know COBOL. Here, since the task is to rewrite the code, decompilation is just to tell you how it works and then you’ll want it written in a modern language. It may be useful to decompile to a different language if such a decompiler is available, say to the C language, which you better understand.
Sure, it may be that C isn’t what the new program will to rewr
