The Linux Kernel Looks To Drop Support For Intel's ICC Compiler

Then work on it and send patches.

back then you had to pay for the ICC and i was not sure how long the it department is going to subscribe for a license (public research facility). Better dont get trapped in the vendor lockin. It was more a "curiosity thing".

I believe ICC is based on Clang these days anyway.

About a year ago Intel announced that they moved to the LLVM stack for their compiler, and phoronix picked that up: https://www.phoronix.com/news/Intel-LLVM-Adoption-C-CPP

And IBM announced their move to the LLVM stack about a year before that for their XL compiler suite.

I believe ICC is based on Clang these days anyway. I know Intel's OneAPI compiler is too.
Embarcadero's BCC moved to Clang too.

Monocultures aren't great but at least it is a fairly decent open-source compiler.

It's all GCC and Clang now, good duo. I remember when ICC produced interesting results, but that was about a decade ago.

My experiments with ICC on Linux always ended sooner or later with a non-bootable or non-usable system, this experience did not improve with the new icx. Case closed.

I think i tried to compile it years ago. But wasnt able to. If i remember it correctly i havent put a lot of work into it because i thought it ist official supported any way so... But it was

Was about time. The ICC compilers were among the most dishonest compilers on the market. They were deliberately crippling the performance of non-Intel CPU's. Intel lost a court case to AMD.

The dead LinuxDNA project likely weeps over this. People really wanted to build Linux with ICC years ago and were actively maintaining patches to do it.

I remember ICC being pretty big in AAA gaming spaces (and some HPC spaces perhaps), but it seems Clang and MSVC are dominating there now (including consoles which use Clang-based compilers).

Dropping more legacy stuff out, great news!
