Do compilers have to be written for each model of CPU?
Do you need to take account of the different processors and their instructions when writing a compiler? Have instructions been standardised? Or what tools and techniques are available to assist with this? E.g. Ignoring machine instructions that are specific to a certain processor model.
Is it possible to use GNU GPL for application that has no source?
I mean, it is possible to create application without source code – for example using HEX editor or some debugger that can assembly instructions (actually every decent debugger can).
What did machine code for 4-bit architecture look like?
I don’t know how a 4-bit instruction could be enough to do something so I read about the Intel 4004 and it says that it used 8-bit instructions and then I can understand how opcode and numbers has enough digits.
Why can’t native machine code be easily decompiled?
With bytecode-based virtual machine languages like Java, VB.NET, C#, ActionScript 3.0, etc., you hear sometimes about how easy it is to just go download some decompiler off the Internet, run the bytecode through it one good time, and oftentimes, come up with something not too far from the original source code in a matter of seconds. Supposedly this sort of language is particularly vulnerable to that.

Is machine language always binary? [duplicate]
This question already has answers here: Is there an alternative to bits? (12 answers) Closed 10 years ago. I know absolutely nothing in low-level stuff, so this will be a very newbie question. Please excuse my ignorance. Is machine language – the series of numbers to that tell the physical computer exactly what to do […]
