[libcxx-commits] [libcxx] [llvm] [libc++][CI] Update to Clang-20 (PR #108761)
Robin Caloudis via libcxx-commits
libcxx-commits at lists.llvm.org
Sun Sep 15 08:17:11 PDT 2024
https://github.com/robincaloudis created https://github.com/llvm/llvm-project/pull/108761
## Why
The release branch for LLVM 19.x is created (`release/19.x`) as anounced [here](https://discourse.llvm.org/t/llvm-19-x-release-branch-created-main-is-now-20-x/80297). As a result, the version on main is now `20.0.0git`. Therefore, we no longer officially support `Clang-17`, but instead `Clang-{18,19,20}`
## What
* Update CI
* Remove `Clang-17` specific code
>From c27b4cba36df9724d5e718b42b778eee296799f3 Mon Sep 17 00:00:00 2001
From: Robin Caloudis <robin.caloudis at gmx.de>
