# Pull more Kbuild updates from Masahiro Yamada: # # - raise minimum supported binutils version to 2.23 # # - remove old CONFIG_AS_* macros that we know binutils >= 2.23 supports # # - move remaining CONFIG_AS_* tests to Kconfig from Makefile # # - enable -Wtautological-compare warnings to catch more issues # # - do not support GCC plugins for GCC <= 4.7 # # - fix various breakages of 'make xconfig' # # - include the linker version used for linking the kernel into # LINUX_COMPILER, which is used for the banner, and also exposed to # /proc/version # # - link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y, which # allows us to remove the lib-ksyms.o workaround, and to solve the last # known issue of the LLVM linker # # - add dummy tools in scripts/dummy-tools/ to enable all compiler tests # in Kconfig, which will be useful for distro maintainers # # - support the single switch, LLVM=1 to use Clang and all LLVM utilities # instead of GCC and Binutils. # # - support LLVM_IAS=1 to enable the integrated assembler, which is still # experimental # # * tag 'kbuild-v5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (36 commits) # kbuild: fix comment about missing include guard detection # kbuild: support LLVM=1 to switch the default tools to Clang/LLVM # kbuild: replace AS=clang with LLVM_IAS=1 # kbuild: add dummy toolchains to enable all cc-option etc. in Kconfig # kbuild: link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y # MIPS: fw: arc: add __weak to prom_meminit and prom_free_prom_memory # kbuild: remove -I$(srctree)/tools/include from scripts/Makefile # kbuild: do not pass $(KBUILD_CFLAGS) to scripts/mkcompile_h # Documentation/llvm: fix the name of llvm-size # kbuild: mkcompile_h: Include $LD version in /proc/version # kconfig: qconf: Fix a few alignment issues # kconfig: qconf: remove some old bogus TODOs # kconfig: qconf: fix support for the split view mode # kconfig: qconf: fix the content of the main widget # kconfig: qconf: Change title for the item window #
