Subject: [PATCH v5 00/12] kbuild: yet another series of cleanups (modpost, LTO, MODULE_REL_CRCS, export.h)
Date: Thu, 12 May 2022 01:45:02 +0900 [thread overview]
Message-ID: <20220511164514.2741934-1-masahiroy@kernel.org> (raw)
This is the third batch of cleanups in this development cycle.
Major changes in v5:
- Fix build errors
- More cleanups
Major changes in v4:
- Move static EXPORT_SYMBOL check to a script
- Some refactoring
Major changes in v3:
- Generate symbol CRCs as C code, and remove CONFIG_MODULE_REL_CRCS.
Major changes in v2:
- V1 did not work with CONFIG_MODULE_REL_CRCS.
I fixed this for v2.
- Reflect some review comments in v1
- Refactor the code more
- Avoid too long argument error
Masahiro Yamada (12):
modpost: split the section mismatch checks into section-check.c
modpost: add sym_find_with_module() helper
modpost: extract symbol versions from *.cmd files
kbuild: link symbol CRCs at final link, removing
CONFIG_MODULE_REL_CRCS
kbuild: stop merging *.symversions
genksyms: adjust the output format to modpost
kbuild: do not create *.prelink.o for Clang LTO or IBT
kbuild: check static EXPORT_SYMBOL* by script instead of modpost
kbuild: make built-in.a rule robust against too long argument error
kbuild: make *.mod rule robust against too long argument error
kbuild: add cmd_and_savecmd macro
kbuild: rebuild multi-object modules when objtool is updated
