+--- 3.11 $(CC) support functions
+
+ The kernel may be build with several different versions of
+ $(CC), each supporting a unique set of features and options.
+ kbuild provide basic support to check for valid options for $(CC).
+ $(CC) is useally the gcc compiler, but other alternatives are
+ available.
+
+ as-option
+ as-option is used to check if $(CC) when used to compile
+ assembler (*.S) files supports the given option. An optional
+ second option may be specified if first option are not supported.
+
+ Example:
+ #arch/sh/Makefile
+ cflags-y += $(call as-option,-Wa$(comma)-isa=$(isa-y),)
+
+ In the above example cflags-y will be assinged the the option
+ -Wa$(comma)-isa=$(isa-y) if it is supported by $(CC).
+ The second argument is optional, and if supplied will be used
+ if first argument is not supported.
+
+ cc-option
+ cc-option is used to check if $(CC) support a given option, and not
+ supported to use an optional second option.
+
+ Example:
+ #arch/i386/Makefile
+ cflags-y += $(call cc-option,-march=pentium-mmx,-march=i586)
+
+ In the above example cflags-y will be assigned the option
+ -march=pentium-mmx if supported by $(CC), otherwise -march-i586.
+ The second argument to cc-option is optional, and if omitted
+ cflags-y will be assigned no value if first option is not supported.
+
+ cc-option-yn
+ cc-option-yn is used to check if gcc supports a given option
+ and return 'y' if supported, otherwise 'n'.
+
+ Example:
+ #arch/ppc/Makefile
+ biarch := $(call cc-option-yn, -m32)
+ aflags-$(biarch) += -a32
+ cflags-$(biarch) += -m32
+
+ In the above example $(biarch) is set to y if $(CC) supports the -m32
+ option. When $(biarch) equals to y the expanded variables $(aflags-y)
+ and $(cflags-y) will be assigned the values -a32 and -m32.
+
+ cc-option-align
+ gcc version >= 3.0 shifted type of options used to speify
+ alignment of functions, loops etc. $(cc-option-align) whrn used
+ as prefix to the align options will select the right prefix:
+ gcc < 3.00
+ cc-option-align = -malign
+ gcc >= 3.00
+ cc-option-align = -falign
+
+ Example:
+ CFLAGS += $(cc-option-align)-functions=4
+
+ In the above example the option -falign-functions=4 is used for
+ gcc >= 3.00. For gcc < 3.00 -malign-functions=4 is used.
+
+ cc-version
+ cc-version return a numerical version of the $(CC) compiler version.
+ The format is <major><minor> where both are two digits. So for example
+ gcc 3.41 would return 0341.
+ cc-version is useful when a specific $(CC) version is faulty in one
+ area, for example the -mregparm=3 were broken in some gcc version
+ even though the option was accepted by gcc.
+
+ Example:
+ #arch/i386/Makefile
+ cflags-y += $(shell \
+ if [ $(call cc-version) -ge 0300 ] ; then \
+ echo "-mregparm=3"; fi ;)
+
+ In the above example -mregparm=3 is only used for gcc version greater
+ than or equal to gcc 3.0.
+
+ cc-ifversion
+ cc-ifversion test the version of $(CC) and equals last argument if
+ version expression is true.
+
+ Example:
+ #fs/reiserfs/Makefile
+ EXTRA_CFLAGS := $(call cc-ifversion, -lt, 0402, -O1)
+
+ In this example EXTRA_CFLAGS will be assigned the value -O1 if the
+ $(CC) version is less than 4.2.
+ cc-ifversion takes all the shell operators:
+ -eq, -ne, -lt, -le, -gt, and -ge
+ The third parameter may be a text as in this example, but it may also
+ be an expanded variable or a macro.

+Module.symvers contains a list of all exported symbols from a kernel build.
+--- 7.1 Symbols fron the kernel (vmlinux + modules)
+
+ During a kernel build a file named Module.symvers will be generated.
+ Module.symvers contains all exported symbols from the kernel and
+ compiled modules. For each symbols the corresponding CRC value
+ is stored too.
+
+ The syntax of the Module.symvers file is:
+ <CRC> <Symbol> <module>
+ Sample:
+ 0x2d036834 scsi_remove_host drivers/scsi/scsi_mod
+
+ For a kernel build without CONFIG_MODVERSIONING enabled the crc
+ would read: 0x00000000
+
+ Module.symvers serve two purposes.
+ 1) It list all exported symbols both from vmlinux and all modules
+ 2) It list CRC if CONFIG_MODVERSION is enabled
+
+--- 7.2 Symbols and external modules
+
+ When building an external module the build system needs access to
+ the symbols from the kernel to check if all external symbols are
+ defined. This is done in the MODPOST step and to obtain all
+ symbols modpost reads Module.symvers from the kernel.
+ If a Module.symvers file is present in the directory where
+ the external module is being build this file will be read too.
+ During the MODPOST step a new Module.symvers file will be written
+ containing all exported symbols that was not defined in the kernel.
+
+--- 7.3 Symbols from another external module
+
+ Sometimes one external module uses exported symbols from another
+ external module. Kbuild needs to have full knowledge on all symbols
+ to avoid spitting out warnings about undefined symbols.
+ Two solutions exist to let kbuild know all symbols of more than
+ one external module.
+ The method with a top-level kbuild file is recommended but may be
+ impractical in certain situations.
+
+ Use a top-level Kbuild file
+ If you have two modules: 'foo', 'bar' and 'foo' needs symbols
+ from 'bar' then one can use a common top-level kbuild file so
+ both modules are compiled in same build.
+
+ Consider following directory layout:
+ ./foo/ <= contains the foo module
+ ./bar/ <= contains the bar module
+ The top-level Kbuild file would then look like:
+
+ #./Kbuild: (this file may also be named Makefile)
+ obj-y := foo/ bar/
+
+ Executing:
+ make -C $KDIR M=`pwd`
+
+ will then do the expected and compile both modules with full
+ knowledge on symbols from both modules.
+
+ Use an extra Module.symvers file
+ When an external module is build a Module.symvers file is
+ generated containing all exported symbols which are not
+ defined in the kernel.
+ To get access to symbols from module 'bar' one can copy the
+ Module.symvers file from the compilation of the 'bar' module
+ to the directory where the 'foo' module is build.
+ During the module build kbuild will read the Module.symvers
+ file in the directory of the external module and when the
+ build is finished a new Module.symvers file is created
+ containing the sum of all symbols defined and not part of the
+ kernel.
