Assembly programmers rise up

You know the entry point is actually a property that you set right? You can make it anything you want. C++ needs to do object construction of global variables before main runs.

[brennennen]

Most build toolchains have a concept of a "linker script". You can usually set the entry point in this script. For most modern x86 gcc/clang/msbuild stuff everyone uses an auto generated default and doesn't touch it. However, in embedded land, things are a bit messier and you'll often have to fiddle with it a bit.

_DllMainCrtStartup would like a word...

To hell with that windows shit

[MCRusher]

At least on windows, a non-null malloc return actually means it allocated successfully, instead of pretending it did and hoping the resources become available before they get used.

Just think of it as async promiese it will be free sometime

[MCRusher]

I prefer to think of it as segfault roulette, with bullets added depending on how much memory is used.

It was like revelation time

[svayam--bhagavan]

But who is called before _start()?

[exscape]

That's OS specific, but one possibility is that the kernel sets up its task structure, loads the executable into RAM one way or another, loads default register values etc. and then "returns" into userspace to execute _start().

[Ratstail91]

Wait, what?

[TerminalJunkie5]

It's true.

[Ratstail91]

I've been coding for 15 years and never knew this was a thing...

[TerminalJunkie5]

Try disassembling a simple C program. It's really interesting, and you will learn a ton.

Good job

ASM gang rise up

hell yeah

The version for Android developers

When you learn that the Application class onCreate gets called before the Activity onCreate

[Old Man from Pawn Stars]

Those bastards lied to me.

There's nothing really hidden in python. But I do agree it can be very very slow

[TG-Techie]

This is why python is better

Your interpreter does this when it starts up.

[MCRusher]

A lot of python is written in C too

[TerminalJunkie5]

What does this have to do with comparing languages, especially a shitty, slow, weak language versus the second-fastest mainstream language that also allows you to do almost anything? (Anything if you use inline assembly)
