From: Nelson Chu Date: Mon, 8 Jun 2020 02:54:53 +0000 (+0800) Subject: RISC-V: Support debug and float CSR as the unprivileged ones. X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=08ccfccf0ed825be9be2972594d4be4a2207ef13;p=deliverable%2Fbinutils-gdb.git RISC-V: Support debug and float CSR as the unprivileged ones. 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.

Let the unprivileged CSR can also be initialized. --- diff --git a/gas/ChangeLog b/gas/ChangeLog index e3e1c4749f..b91d6afe74 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,37 @@ +2020-06-30 Nelson Chu + + * config/tc-riscv.c (riscv_csr_class_check): Removed.
