clang versions prior to the current development version of 13.0.0 cannot compile s390 after commit 3abbdfde5a65 ("s390/bitops: use register pair instead of register asm") and the s390 maintainers do not intend to work around this in the kernel. Codify this in scripts/min-tool-version.sh similar to arm64 with GCC 5.1.0 so that there are no reports of broken builds. [hca@linux.ibm.com: breaking compatibility with older clang compilers is intended to finally make use of a feature which allows the compiler to allocate even/odd register pairs. This is possible since a very long time with gcc, but only since llvm-project commit d058262b1471 ("[SystemZ] Support i128 inline asm operands.") with clang. Using that feature allows to get rid of error prone register asm statements, of which the above named kernel commit is only the first of a larger not yet complete series.] Reported-by: Naresh Kamboju <naresh.kamboju@linaro.org> Signed-off-by: Nathan Chancellor <nathan@kernel.org> Acked-by: Nick Desaulniers <ndesaulniers@google.com> Acked-by: Masahiro Yamada <masahiroy@kernel.org> Link: https://lore.kernel.org/r/20210617193139.856957-1-nathan@kernel.org Signed-off-by: Heiko Carstens <hca@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
