[PATCH v2 4/4] RISC-V: Add address printer tests on disassembler

Tue Aug 2 05:54:21 GMT 2022
This commit adds address printer tests on the disassembler focusing on
various path to/on maybe_print_address. It also tests whether the address
adjustment on RV32 (fix to PR29342) works as expected and whether the
highest address is printed with a symbol.
gas/ChangeLog:
* testsuite/gas/riscv/dis-addr-1.s: New address printer tests
on the disassembler.
* testsuite/gas/riscv/dis-addr-1-32.d: Likewise.
* testsuite/gas/riscv/dis-addr-1-64.d: Likewise.
* testsuite/gas/riscv/dis-addr-2.s: New address printer tests
on the disassembler if `gp' is the highest address.
* testsuite/gas/riscv/dis-addr-2-32.d: Likewise.
* testsuite/gas/riscv/dis-addr-2-64.d: Likewise.
