Commit b753101a authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'kbuild-v5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

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

These two variables allow to override the user@host string displayed during
boot and in /proc/version. The default value is the output of the commands
whoami and host, respectively.

If this variable is set to 1, Kbuild will use Clang and LLVM utilities instead
of GCC and GNU binutils to build the kernel.

LLVM Utilities
--------------
LLVM has substitutes for GNU binutils utilities. These can be invoked as
additional parameters to `make`.
LLVM has substitutes for GNU binutils utilities. Kbuild supports `LLVM=1`
to enable them.
make CC=clang AS=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \\
OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump OBJSIZE=llvm-objsize \\
make LLVM=1
They can be enabled individually. The full list of the parameters:

Currently, the integrated assembler is disabled by default. You can pass
`LLVM_IAS=1` to enable it.

# Staring v4.18, Kconfig evaluates compiler capabilities, and hides CONFIG
# options your compiler does not support. This works well if you configure and
# build the kernel on the same host machine.
#
# It is inconvenient if you prepare the .config that is carried to a different
# build environment (typically this happens when you package the kernel for
# distros) because using a different compiler potentially produces different
# CONFIG options than the real build environment. So, you probably want to make
# as many options visible as possible. In other words, you need to create a
# super-set of CONFIG options that cover any build environment. If some of the
# CONFIG options turned out to be unsupported on the build machine, they are
# automatically disabled by the nature of Kconfig.
#
# However, it is not feasible to get a full-featured compiler for every arch.
# Hence these dummy toolchains to make all compiler tests pass.
#
# Usage:
#
# From the top directory of the source tree, run
#
# $ make CROSS_COMPILE=scripts/dummy-tools/ oldconfig
#
# Most of compiler features are tested by cc-option, which simply checks the
# exit code of $(CC). This script does nothing and just exits with 0 in most
# cases. So, $(cc-option, ...) is evaluated as 'y'.
#
# This scripts caters to more checks; handle --version and pre-process __GNUC__
# etc. to pretend to be GCC, and also do right things to satisfy some scripts.
# Check if the first parameter appears in the rest. Succeeds if found.
# This helper is useful if a particular option was passed to this script.
