b16838c608ef97c29896518117c30a2aa3931fac - kbuild: trace functions in subdirectories of lib/

Tue, 07 Jul 2020 11:21:17 +0200

kbuild: trace functions in subdirectories of lib/ccflags-remove-$(CONFIG_FUNCTION_TRACER) += $(CC_FLAGS_FTRACE)exists here in sub-directories of lib/ to keep the behavior ofcommit 2464a609ded0 ("ftrace: do not trace library functions").Since that commit, not only the objects in lib/ but also the ones inthe sub-directories are excluded from ftrace (although the commitdescription did not explicitly mention this).However, most of library functions in sub-directories are not so hot.Re-add them to ftrace.Going forward, only the objects right under lib/ will be excluded.Cc: Ingo Molnar Signed-off-by: Masahiro Yamada Acked-by: Steven Rostedt (VMware) List of files: /linux/lib/zlib_inflate/Makefile

15d5761ad31dfb194ebe76554e6af0437eb20424 - kbuild: introduce ccflags-remove-y and asflags-remove-y

Tue, 07 Jul 2020 11:21:16 +0200

kbuild: introduce ccflags-remove-y and asflags-remove-yCFLAGS_REMOVE_.o filters out flags when compiling a particularobject, but there is no convenient way to do that for every object ina directory.Add ccflags-remove-y and asflags-remove-y to make it easily.Use ccflags-remove-y to clean up some Makefiles.The add/remove order works as follows: [1] KBUILD_CFLAGS specifies compiler flags used globally [2] ccflags-y adds compiler flags for all objects in the current Makefile [3] ccflags-remove-y removes compiler flags for all objects in the current Makefile (New feature) [4] CFLAGS_ adds compiler flags per file. [5] CFLAGS_REMOVE_ removes compiler flags per file.Having [3] before [4] allows us to remove flags from most (but not all)objects in the current Makefile.For example, kernel/trace/Makefile removes $(CC_FLAGS_FTRACE)from all objects in the directory, then adds it back totrace_selftest_dynamic.o and CFLAGS_trace_kprobe_selftest.oThe same applies to lib/livepatch/Makefile.Please note ccflags-remove-y has no effect to the sub-directories.In contrast, the previous notation got rid of compiler flags also fromall the sub-directories.The following are not affected because they have no sub-directories: arch/arm/boot/compressed/ arch/powerpc/xmon/ arch/sh/ kernel/trace/However, lib/ has several sub-directories.To keep the behavior, I added ccflags-remove-y to all Makefilesin subdirectories of lib/, except the following: lib/vdso/Makefile - Kbuild does not descend into this Makefile lib/raid/test/Makefile - This is not used for the kernel buildI think commit 2464a609ded0 ("ftrace: do not trace library functions")excluded too much. In the next commit, I will remove ccflags-remove-yfrom the sub-directories of lib/.Suggested-by: Sami Tolvanen Signed-off-by: Masahiro Yamada Acked-by: Steven Rostedt (VMware) Acked-by: Michael Ellerman (powerpc)Acked-by: Brendan Higgins (KUnit)Tested-by: Anders Roxell List of files: /linux/lib/zlib_inflate/Makefile
