--- Comment #1 from Jeffrey A. Law <law at gcc dot gnu.org> ---
I should have added some comments on why this was moved to SUSPENDED.

Difference of label support requires special relocation support in the
assembler and linker, particularly in the presence of relaxing.  While RISC-V
has some support in this space, it's limited.

There is currently no consumer for location views downstream (ie gdb) and thus
adding support for general difference of labels in the assembler/linker isn't
high on anyone's list.

So suspending until such point as location views are useful, at which point
we'll reopen and have to dig into this again, though I suspect it'll largely be
a binutils issue.
