Subject: [PATCH 00/13] kbuild: refactoring after Clang LTO
Date: Thu, 19 Aug 2021 09:57:31 +0900 [thread overview]
Message-ID: <20210819005744.644908-1-masahiroy@kernel.org> (raw)
The introduction of Clang LTO, the kbuild code became much
uglier due to CONFIG_LTO_CLANG conditionals.
It is painful to maintain the messed-up code, and to review
code changed on top of that.
Masahiro Yamada (13):
kbuild: move objtool_args back to scripts/Makefile.build
gen_compile_commands: extract compiler command from a series of
commands
kbuild: detect objtool changes correctly and remove .SECONDEXPANSION
kbuild: remove unused quiet_cmd_update_lto_symversions
kbuild: remove stale *.symversions
kbuild: merge vmlinux_link() between the ordinary link and Clang LTO
kbuild: do not remove 'linux' link in scripts/link-vmlinux.sh
kbuild: merge vmlinux_link() between ARCH=um and other architectures
kbuild: do not create built-in.a.symversions or lib.a.symversions
kbuild: build modules in the same way with/without Clang LTO
kbuild: always postpone CRC links for module versioning
kbuild: merge cmd_modversions_c and cmd_modversions_S
kbuild: merge cmd_ar_builtin and cmd_ar_module
