Subject: [PATCH bpf-next 0/5] Allow CONFIG_DEBUG_INFO_DWARF5=y + CONFIG_DEBUG_INFO_BTF=y
Date: Tue, 1 Feb 2022 13:56:19 -0700 [thread overview]
Message-ID: <20220201205624.652313-1-nathan@kernel.org> (raw)
Hi all,
This series allows CONFIG_DEBUG_INFO_DWARF5 to be selected with
CONFIG_DEBUG_INFO_BTF=y by checking the pahole version.
The first four patches add CONFIG_PAHOLE_VERSION and
scripts/pahole-version.sh to clean up all the places that pahole's
version is transformed into a 3-digit form.
The fourth patch adds a PAHOLE_VERSION dependency to DEBUG_INFO_DWARF5
so that there are no build errors when it is selected with
DEBUG_INFO_BTF.
I build tested Fedora's aarch64 and x86_64 config with ToT clang 14.0.0
and GCC 11 with CONFIG_DEBUG_INFO_DWARF5 enabled with both pahole 1.21
and 1.23.
