| From | Sami Tolvanen <> | Subject | [PATCH 12/15] arm64: explicitly pass --no-fix-cortex-a53-843419 to GNU gold | Date | Fri, 3 Nov 2017 10:11:59 -0700 |
| |
Some versions of GNU gold are known to produce broken code with --fix-cortex-a53-843419 as explained in this bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=21491
If ARM64_ERRATUM_843419 is disabled and we're using GNU gold, pass --no-fix-cortex-a53-843419 to the linker to ensure the erratum fix is not used even if the linker is configured to enable it by default.
