<pre>
    This was discussed briefly years ago in the context of potentially implementing "fine grain kernel address space layout randomization" for the Linux kernel, which has somewhat stalled.

https://github.com/ClangBuiltLinux/linux/issues/1184

It seems like [binutils 2.36 BFD implemented](https://lists.gnu.org/archive/html/info-gnu/2021-01/msg00015.html) implemented support for `-z unique_symbol` .

https://sourceware.org/binutils/docs/ld/Options.html documents this as:
> Avoid duplicated local symbol names in the symbol string table. Append ".number" to duplicated local symbol names if ‘unique-symbol’ is used. nounique-symbol is the default.

Since the work on FGKASLR has somewhat stalled, the priority of this feature in LLD is low/unclear, but filing a bug "upstream" to track this request for others to follow allong.
