| 2021-06-28 | scripts/min-tool-version.sh: Raise minimum clang version to 13.0.0 for s390 | Nathan Chancellor | |
| 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> | |||
| 2021-04-25 | kbuild: collect minimum tool versions into scripts/min-tool-version.sh | Masahiro Yamada | |
| The kernel build uses various tools, many of which are provided by the same software suite, for example, LLVM and Binutils. When you raise the minimum version of Clang/LLVM, you need to update clang_min_version in scripts/cc-version.sh and also lld_min_version in scripts/ld-version.sh. Kbuild can handle CC=clang and LD=ld.lld independently, but it does not make much sense to maintain their versions separately. Let's create a central place of minimum tool versions so you do not need to touch multiple files. scripts/min-tool-version.sh prints the minimum version of the given tool.
