Glad GCC is moving into the direction of human-readable parsing! Back in my day (like 15 years ago) any error would return a stack of unreadable template expansions.

Still, I wonder if GCC is the best tool for this visualisation. Shouldn't it be in the realm of GDB, Valgrind, or other debuggers?

I was just thinking that our core tools don't have enough indecipherable punctuation.

That's not ASCII, but it does look like a nice improvement.

I actually like the use of the warning sign emoji too.

I wonder why Phoronix enabled such levels of protection? All I can think of is that their forum is pretty toxic. But surely nobody would DDoS phoronix.com just because they were insulted for liking Wayland or, god forbid, Windows.

I didn't have any of that. Just a modal saying to please disable my adblocker. I'm using ublock origin and privacy badger in firefox.

Yes, a big warning during compilation is thousand times better than getting it during debugging and profiling. Because everybody must compile, but few people use GDB, and even fewer people use Valgrind.

You can pass -fdiagnostics-text-art-charset=[none|ascii|unicode|emoji] if you want real ASCII.

ASCII Art refers to the style of the art.

Similar to “8-bit” art (which may be in a 24-bit colour space)
