[PATCH v3 0/2] RISC-V: Fix abort when displaying data and add test

[Charlie Jenkins]

Commit 6a04e8230707 ("RISC-V: Fix display of partial instructions")
changed how objdump displays instructions. This enabled data of any size
to be dumped. riscv_disassemble_data() only supports data of size 1,
2, 4, or 8 bytes and any other number would cause an abort.

Instead of aborting when encountering one of the other values, dump the
data as ".<N>byte <val>", similar to what is done for instructions with
".insn <N>, <val>".
