Subject: [REVIEW ONLY 1/2] NEAR-RATIFICATION RISC-V: Add 'Ssstateen' extension and its CSRs
Date: Thu, 3 Nov 2022 12:26:28 +0000 [thread overview]
Message-ID: <283a86ebf0941f0f63dc1a590ec3d547bd5d69e8.1667478033.git.research_trasio@irq.a4lg.com> (raw)
In-Reply-To: <cover.1667478033.git.research_trasio@irq.a4lg.com>
[DO NOT MERGE]
RISC-V Profiles are frozen but -- from my view -- this document will still
change in some way. Meanwhile, this patch should not be merged upstream.
This commit uses tentative version 1.0 (same as 'Smstateen').
This commit adds 'Ssstateen' extension, which is a supervisor-visible view
of the 'Smstateen' extension. It means, this extension implements sstateen*
and hstateen* CSRs of the 'Smstateen' extension.
Note that 'Smstateen' extension itself is unchanged but due to
implementation simplicity, it is implemented so that 'Smstateen' implies
'Ssstateen' (just like 'M' implies 'Zmmul').
This is based on the latest version of RISC-V Profiles (version 0.9-draft):
<https://github.com/riscv/riscv-profiles/commit/226b7f643067b29abc6723fac60d5f6d3f9eb901>
bfd/ChangeLog:
* elfxx-riscv.c (riscv_implicit_subsets): Update implication rules.
(riscv_supported_std_s_ext) Add 'Ssstateen' extension.
gas/ChangeLog:
* config/tc-riscv.c (enum riscv_csr_class): Rename
CSR_CLASS_SMSTATEEN_AND_H{,_32} to CSR_CLASS_SSSTATEEN_...
Add CSR_CLASS_SSSTATEEN.
(riscv_csr_address): Support new/renamed CSR classes.
* testsuite/gas/riscv/csr.s: Add 'Ssstateen' extension to comment.
* testsuite/gas/riscv/csr-version-1p9p1.l: Reflect changes to
error messages.
* testsuite/gas/riscv/csr-version-1p10.l: Likewise.
* testsuite/gas/riscv/csr-version-1p11.l: Likewise.
* testsuite/gas/riscv/csr-version-1p12.l: Likewise.
* testsuite/gas/riscv/ssstateen-csr.s: Test for 'Ssstateen' CSRs.
* testsuite/gas/riscv/ssstateen-csr.d: Likewise.
* testsuite/gas/riscv/smstateen-csr-s.d: Test to make sure that
supervisor/hypervisor part of 'Smstateen' CSRs are accessible from
'RV32IH_Smstateen', not just from 'RV32IH_Ssstateen' that is tested
in ssstateen-csr.d.
include/ChangeLog:
* opcode/riscv-opc.h: Update DECLARE_CSR declarations with
new CSR classes.
