Subject: Regression: commit 987fdfec2410 causes build to incorrectly issue warning
Date: Fri, 2 Jul 2021 14:13:01 +0100 [thread overview]
Message-ID: <20210702131301.GD1350@shell.armlinux.org.uk> (raw)
Hi,
Commit 987fdfec2410 ("arm64: move --fix-cortex-a53-843419 linker test to
Kconfig") breaks the ability to detect linker support for this option.
Building 5.13 for aarch64 with Debian binutils 2.31.1 results in:
.../arch/arm64/Makefile:25: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum
This is because ARM64_LD_HAS_FIX_ERRATUM_843419 is not set in the
Kconfig, indicating that the Kconfig test for linker support for
--fix-cortex-a53-843419 has failed, yet this version of binutils does
support this option:
$ aarch64-linux-gnu-ld --help | grep -e --fix-cortex-a53-843419 | wc -l
8
Reverting this commit fixes the problem for me.
Thanks.
