Merge git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild
* git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild: (33 commits) xtensa: use DATA_DATA in xtensa powerpc: add missing DATA_DATA to powerpc cris: use DATA_DATA in cris kallsyms: remove usage of memmem and _GNU_SOURCE from scripts/kallsyms.c kbuild: use -fno-optimize-sibling-calls unconditionally kconfig: reset generated values only if Kconfig and .config agree. kbuild: fix the warning when running make tags kconfig: strip 'CONFIG_' automatically in kernel configuration search kbuild: use POSIX BRE in headers install target Whitelist references from __dbe_table to .init modpost white list pattern adjustment kbuild: do section mismatch check on full vmlinux kbuild: whitelist references from variables named _timer to .init.text kbuild: remove hardcoded _logo names from modpost kbuild: remove hardcoded apic_es7000 from modpost kbuild: warn about references from .init.text to .exit.text kbuild: consolidate section checks kbuild: refactor code in modpost to improve maintainability kbuild: ignore section mismatch warnings originating from .note section kbuild: .paravirtprobe section is obsolete, so modpost doesn't need to handle it ...

be an expanded variable or a macro.

cc-fullversion
|
||||
cc-fullversion is useful when the exact version of gcc is needed.
|
||||
One typical use-case is when a specific GCC version is broken.
|
||||
cc-fullversion points out a more specific version than cc-version does.
|
||||
|
||||
Example:
|
||||
#arch/powerpc/Makefile
|
||||
$(Q)if test "$(call cc-fullversion)" = "040200" ; then \
|
||||
echo -n '*** GCC-4.2.0 cannot compile the 64-bit powerpc ' ; \
|
||||
false ; \
|
||||
fi
|
||||
|
||||
In this example for a specific GCC version the build will error out explaining
|
||||
to the user why it stops.
