[PATCH 12/13] kbuild: merge cmd_modversions_c and cmd_modversions_S

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now cmd_modversions_c and cmd_modversions_S are similar.

The latter uses $(OBJDUMP) -h, but it can be replaced with $(NM).

$(NM) works for both ELF and LLVM bitcode (if $(NM) is llvm-nm).
