Subject: [PATCH] scripts/min-tool-version.sh: Raise minimum clang version to 13.0.0 for s390
Date: Thu, 17 Jun 2021 12:31:40 -0700	[thread overview]
Message-ID: <20210617193139.856957-1-nathan@kernel.org> (raw)
In-Reply-To: <YMtib5hKVyNknZt3@osiris>

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.

Reported-by: Naresh Kamboju <naresh.kamboju@linaro.org>
Signed-off-by: Nathan Chancellor <nathan@kernel.org>

This should probably go through the s390 tree with Masahiro's ack.
