Hi all, Christian sent a fix [1] for ARM_VECTORS with CONFIG_LD_DEAD_CODE_DATA_ELIMINATION that exposed a deficiency in ld.lld with regards to KEEP() within an OVERLAY description. I have fixed that in ld.lld [2] and added a patch before Christian's to disallow CONFIG_LD_DEAD_CODE_DATA_ELIMINATION when KEEP() cannot be used within OVERLAY to keep everything working for all linkers.
