[PATCH v4 4/4] RISC-V: Add address printer tests on disassembler
Tsukasa OI

Tue Aug 9 03:44:27 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, whether the highest
address is printed with a symbol and JALR address computation is fixed.
gas/ChangeLog:
* testsuite/gas/riscv/dis-addr-a.s: Rename from auipc-x0.s.
* testsuite/gas/riscv/dis-addr-a.d: Rename from auipc-x0.d.
* testsuite/gas/riscv/dis-addr-2.s: New address printer tests
on the disassembler.
* testsuite/gas/riscv/dis-addr-2-32.d: Likewise.
* testsuite/gas/riscv/dis-addr-2-64.d: Likewise.
* testsuite/gas/riscv/dis-addr-3.s: New address printer tests
on the disassembler if `gp' is the highest address.
* testsuite/gas/riscv/dis-addr-3-32.d: Likewise.
* testsuite/gas/riscv/dis-addr-3-64.d: Likewise.
