            Bug ID: 105172
           Summary: RV64: gcc generates R_RISCV_ALIGN with a
                    non-power-of-two value
           Product: gcc
           Version: 11.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

It is reported against the mold linker
(https://github.com/rui314/mold/issues/419), but I believe it's GCC"s bug.

It looks like GCC sometimes create a R_RISCV_ALIGN relocation with a
non-power-of-two requirement alignment, as you can see in the above bug report.
That simply doesn't make sense and strongly suggests that something is not
working as intended in GCC. I believe all R_RISV_ALIGN relocations have a
power-of-two value.
