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
