Hello,

I am not sure what you mean with misplaced. If you mean the position
in the file: Can't help that, it comes out of target.def that way. If
you mean the text itself, yes, that looks like something I tried in an
older iteration of this patch (target hook returning a .ident string).
In the following documentation, the "Generate a string" is replaced by
"Output a string". Is that better? Otherwise, can you please clarify
what you would like to see different here?

Thanks,

Ciao!
Steven

 Write the assembly code to define section anchor @var{x}, which is a
 @code{SYMBOL_REF} for which @samp{SYMBOL_REF_ANCHOR_P (@var{x})} is true.
