It's a feature introduced to migrate a security issue. openEuler 20.03 doesn't support it. Have we supported it in master branch or do we have plan to support it?

OpenEuler does not support -mlfence-after-load=yes, which is a security feature of binutils and is supported only on x86. We have no plan to support this feature at this time because it has a significant impact on performance.
