Phoronix: LLVM Clang Compiling The Linux Kernel Is A Big Topic For 2015

It's been talked about for years and is still an ongoing but very active endeavor: building the mainline Linux kernel with LLVM's Clang compiler rather than GCC...

GCC has improved a lot lately. I missed built-in functions for arithmetic with overflow checking that were in clang but not gcc.

Gcc sucks so much it was only able to bring us a working linux kernel in the previous 20 years.

While I'm rooting for Clang in this situation (and pretty much in general), GCC does not suck. It has a few problems here and there, but by-and-large it's still one of the best (if not _the_ best) C/C++ compilers in the world.

Respect it, because it brought you (and continues to bring you) the Linux you love so much.

Wasn't that exactly the point that bulletxt was making?

You know... I first replied as soon as I got home from work. Now that I have a bit of sense about me... I can see the sarcasm dripping off of his comment.

Work fries your brain...

GCC is probably the best compiler available, but Linux will benefit from Clang/llvm. It will help ironing bugs. GCC and llvm should benefit from this as well:

Complacency brings a sense of superiority. Nothing about GCC and a best compiler available has any sense of fact to it.

Well GCC might force you to open source your code by propagating copyleft thoughts and force you to eat your toenails in a public event.

It's not about complacency, but number of supported architectures, matureness and wide range of software which is compiled by GCC. No other compiler is even close to it.
