RISC-V: Support debug and float CSR as the unprivileged ones.

[thirdparty/binutils-gdb.git] / gas / ChangeLog

2020-06-30  Nelson Chu  <nelson.chu@sifive.com>

        * config/tc-riscv.c (riscv_csr_class_check): Removed.  Move the
        checking into riscv_csr_address.
        (riscv_csr_version_check): Likewise.
        (riscv_csr_address): New function.  Return the suitable CSR address
        after checking the ISA dependency and versions.  Issue warnings if
        we find any conflict and -mcsr-check is set.  CSR_CLASS_F and
        CSR_CLASS_DEBUG are unprivileged CSR for now, so don't check the
        priv spec versions for them.
        (reg_csr_lookup_internal): Call riscv_csr_address to find the
        suitable CSR address.
        * testsuite/gas/riscv/priv-reg-fail-fext.d: Remove -mpriv-spec=1.11.
        * testsuite/gas/riscv/priv-reg-fail-read-only-01.d: Likewise.
        * testsuite/gas/riscv/priv-reg-fail-rv32-only.d: Likewise.
        * testsuite/gas/riscv/priv-reg-fail-fext.l:  We don't care the
        priv spec warnings here.  These warnings are added by accident.

        * testsuite/gas/riscv/priv-reg-fail-version-1p9.l: Updated since
        dscratch0 and dscratch1 are regarded as the unprivileged CSR rather
        than the privileged ones.
        * testsuite/gas/riscv/priv-reg-fail-version-1p9p1.l: Likewise.
        * testsuite/gas/riscv/priv-reg-fail-version-1p10.l: Likewise.
