Subject: [PATCH 5.15 35/36] lib/Kconfig.debug: Allow BTF + DWARF5 with pahole 1.21+
Date: Thu, 23 Feb 2023 14:07:11 +0100 [thread overview]
Message-ID: <20230223130430.666971176@linuxfoundation.org> (raw)
In-Reply-To: <20230223130429.072633724@linuxfoundation.org>
From: Nathan Chancellor <nathan@kernel.org>
commit 42d9b379e3e1790eafb87c799c9edfd0b37a37c7 upstream.
Commit 98cd6f521f10 ("Kconfig: allow explicit opt in to DWARF v5")
prevented CONFIG_DEBUG_INFO_DWARF5 from being selected when
CONFIG_DEBUG_INFO_BTF is enabled because pahole had issues with clang's
DWARF5 info. This was resolved by [1], which is in pahole v1.21.
Allow DEBUG_INFO_DWARF5 to be selected with DEBUG_INFO_BTF when using
pahole v1.21 or newer.
