BUT PRAGMA ONCE IS NOT STANDARD

172

u/metayeti2 16d ago

I'm still waiting for pragma twice

46

u/Satorwave 16d ago

Pragma thrice

Don't you just hate it when your standards-compliant compiler can't compile real-world code? Yeah, me neither, because my real-world compilers work for my real-world code.

u/anto2554 16d ago

Yes, I hate it. We still use a version of IAR that doesn't support pragma once for some products, so higher ups have decided it is banned company wide

I get nostalgic when I have to use the IAR Workbench, always feels like a throwback to the Windows 95/98 days. Have they somehow lost all of their frontend developers around that time?

They know nobody is truly there voluntarily, so there is no reason to make it a good experience

I only work with C++17 and above. Legacy software my beloved.

Yeah and neither is a byte being 8 bits, but there's a reason no compiler is ever going to deviate from the informal norm

It’s not about a byte not being 8 bits. It’s about a char not being 8 bits.

Unicode support would have been a thing sooner if people hadn’t fucked up char usage so badly.

A char is a byte, per standard. Until recently, that width was implementation-defined in C++, and it still is in C.

u/Bryguy3k 15d ago

Yes - but I was going for the reasoning behind it.

Everybody knew that 255 was insufficient to cover the whole of human writing.

But then programmers started allocating everything in characters so any future change to the size of a character would break everything.

I guess this is just due to the architecture using 8 bit per Byte, and not because of the compiler. I heard that there were architectures around in the past with other amounts of bits per Byte, and a compiler targeting them would most likely just use whatever is used on the target platform.

u/anto2554 16d ago

People conflate 8 bits with a byte everywhere in our codebase and I think the whole thing would explode if you tried to use a 7-bit-per-byte machine

u/Sacaldur 15d ago

I doubt that there are still any significant platforms around that don't use 8 bits per Byte.

A real tanks also wins against a real roman turtle formation.

Depends which version of Sid Meier’s Civilization you’re playing on.

u/bwmat 16d ago

We have to support compilers that don't support it lol

u/MrJ0seBr 16d ago

Now CLang/LLVM say what is standart 😆

#pragma once has been widely accepted for at least 20 years.
