Subject: [PATCH v2 10/12] lib/Kconfig.debug: Drop CLANG_VERSION check from DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT
Date: Thu, 21 Aug 2025 14:15:47 -0700 [thread overview]
Message-ID: <20250821-bump-min-llvm-ver-15-v2-10-635f3294e5f0@kernel.org> (raw)
In-Reply-To: <20250821-bump-min-llvm-ver-15-v2-0-635f3294e5f0@kernel.org>
Now that the minimum supported version of LLVM for building the kernel
has been bumped to 15.0.0, the CLANG_VERSION check for older than 14.0.0
is always false, so remove it.

The implicit default version of DWARF debug info produced by a
toolchain changes over time.
