LLVM Clang 19 Branched, LLVM 20 Enters Development- No AMD Zen 5 "Znver5" Merged Yet


As scheduled, LLVM Clang 19 was branched from mainline Git this morning and is now considered feature frozen ahead of its planned September release

As scheduled, LLVM Clang 19 was branched from mainline Git this morning and is now considered feature frozen ahead of its planned September release. One frustrating element is that even with the LLVM/Clang 19 branch date known in advance, LLVM/Clang 19 (or mainline LLVM Git or any open merge request for LLVM) at this time doesn't yet have the AMD Zen 5 " znver5" target added. It was great seeing Znver5 make it early for GCC 14 but for LLVM/Clang it's running late and also still a ways off from Intel's approach of often having new CPU targets added to the open-source compilers a year or more in advance to allow the support to work its way out to the various Linux distributions and software repositories well in advance of product launches.
