x86 instructions to C?

[guest271314]

I have nexe file (x86 instructions). I want to decompile the file to C/C++. Is that possible?

It's possible but very tricky and error prone in general. Some commercial packages like HexRays can do it, albeit not to anything very human-readable without a lot of user help. See https://stackoverflow.com/questions/14308610/how-hard-is-it-really-to-decompile-assembly-code for example.

It's not something Compiler Explorer does (nor any time likely) - we have a bug open for Ghidra support but I don't think Ghidra supports automated decompilation in the same way as HexRays.

hexdump and strings give a peek https://gist.github.com/guest271314/4894662d31ffb4ad2cd57683721bf4b4.

Neither are anywhere near close to C though. If anything, the disassembly we show in CE is much nearer to "C" than either a hexdump, or a string list. If you want to disassemble an existing file, try objdump -d

I tried that, too.

If I am not mistaken, even if I am able to disassemble and re-assemble the code, won't I still need the libraries referenced therein to re-compile the code?

I filed this request to Google GoogleChrome/developer.chrome.com#2295.

The source could very well be written in Go. I don't know. The source code is evidently restricted to "Googlers"

This is for Googlers only.

It's possible - but not on Compiler Explorer: see above.

There's now a site called dogbolt.org that provides a service more like the original poster wanted.
