The unprivileged CSR should be controlled by other specific specs rather than the privileged spec. For example, the debug CSR should be controlled by the debug spec, and the float CSR should be controlled by the float spec. User may use assembler options to choose what the debug and other specs they want, or may encode the versions of specs into the architecture string directly. Since we haven't decided which one is better, we set the defined and aborted versions of unprivileged CSR to PRIV_SPEC_CLASS_NONE in the include/opcode/riscv-opc.h, to tell assembler don't check priv spec versions for them. However, these PRIV_SPEC_CLASS_NONE will be changed to FLOAT_SPEC_CLASS_* and DEBUG_SPEC_CLASS_* in the future. gas/ * 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. Remove them and only focus on the ISA dependency warnings. * testsuite/gas/riscv/priv-reg-fail-rv32-only.l: Likewise. * testsuite/gas/riscv/priv-reg-fail-read-only-01.l: Likewise. * 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. * testsuite/gas/riscv/priv-reg-fail-version-1p11.l: Likewise. * testsuite/gas/riscv/priv-reg.s: Likewise. Add missing debug CSR. * testsuite/gas/riscv/priv-reg-version-1p9.d: Likewise. * testsuite/gas/riscv/priv-reg-version-1p9p1.d: Likewise. * testsuite/gas/riscv/priv-reg-version-1p10.d: Likewise. * testsuite/gas/riscv/priv-reg-version-1p11.d: Likewise. * testsuite/gas/riscv/csr-dw-regnums.d: Likewise. * testsuite/gas/riscv/csr-dw-regnums.s: Likewise. include/ * opcode/riscv-opc.h: Support the unprivileged CSR. The versions of the unprivileged CSR should be PRIV_SPEC_CLASS_NONE for now. * opcode/riscv.h (enum riscv_csr_class): Add CSR_CLASS_DEBUG. opcodes/ * riscv-dis.c (print_insn_args, case 'E'): Updated. Let the unprivileged CSR can also be initialized. |
