This patch series presents the comprehensive implementation of the MAC and ALU
extension for CORE-V.

Tested with riscv-gnu-toolchain on binutils, ld, gas and gcc testsuites to
ensure its correctness and compatibility with the existing codebase.
However, your input, reviews, and suggestions are invaluable in making this
extension even more robust.

The CORE-V instructions are described in the specification [1] and work can be
found in the OpenHW group's Github repository [2].

opcodes/ChangeLog:

	* riscv-dis.c (print_insn_args): Disassemble information with
          the EXTRACT macro implemented.
	* riscv-opc.c: Defined the MASK and added
          XCVmac instructions.

include/ChangeLog:

	* opcode/riscv-opc.h: Added corresponding MATCH and MASK macros
          for XCVmac.

Hi,

I just noticed that - it isn't clear from the old code that the operands,
which are named starting with X, are reserved for vendors.  Therefore, I
sent the patch to clarify the vendor operands' naming rules,
https://sourceware.org/pipermail/binutils/2023-September/129414.html.  So
that everything vendor operands will be named starting with X, and then
follows one letter (or a keyword in the future) to represent which vendors
belonged.

Thanks
Nelson

Considering consistency, it's better to use `X'.

Use c to represent vendor core-v looks reasonable.

Hi Mary,

Thanks for the contribution, the vendor core-v extensions in binutils look
good to me :-)

Hi Jeff, Kito, Palmer and Andrew,

I am not sure if we are likely to accept the vendor core-v extension only
in binutils first?  Or if we prefer to accept it with the whole toolchain
support, including gcc and qemu.  Need your help, thanks!

If I forgot to cc anyone who may be related, please feel free to add them
in the discussion!

Nelson

I am open mind to accept Core-v support for GNU toolchain, and I think
binutils should support first :P

Hi,

In general, I request one large change to your patch set.

> +{"cv.mac",      0, INSN_CLASS_XCVMAC, "d,s,t",    MATCH_CV_MAC,	     MASK_CV_MACMSU, match_opcode, 0},
> +{"cv.msu",      0, INSN_CLASS_XCVMAC, "d,s,t",    MATCH_CV_MSU,	     MASK_CV_MACMSU, match_opcode, 0},
MASK values should be per (non-alias) instruction.  Yes, that would make
many MASK macros with different names but per-instruction MASK value is
riscv-opcodes friendly and makes inspecting the opcodes easier.

So, please make MASK values per-instruction as well as MATCH values and
order like:

-   MATCH_CV_MAC
-   MASK_CV_MAC
-   MATCH_CV_MSU
-   MASK_CV_MSU
-   MATCH_CV_MULSN
-   MASK_CV_MULSN
-   MATCH_CV_MULSRN
-   MASK_CV_MULSRN...

in PATCH 1/2 and likewise in PATCH 2/2.

Otherwise it looks good (I haven't closely inspected yet though).

Thanks,
Tsukasa

Changes: v1 -> v2
 - Added MASK_<INSN> for each instruction, as suggested
 - Changed operand 'x' to operand 'X', as suggested

This patch series presents the comprehensive implementation of the MAC and ALU
extension for CORE-V.

Tested with riscv-gnu-toolchain on binutils, ld, gas and gcc testsuites to
ensure its correctness and compatibility with the existing codebase.
However, your input, reviews, and suggestions are invaluable in making this
extension even more robust.

The CORE-V instructions are described in the specification [1] and work can be
found in the OpenHW group's Github repository [2].

opcodes/ChangeLog:

	* riscv-dis.c (print_insn_args): Disassemble information with
          the EXTRACT macro implemented.
	* riscv-opc.c: Defined the MASK and added
          XCVmac instructions.

include/ChangeLog:

	* opcode/riscv-opc.h: Added corresponding MATCH and MASK macros
          for XCVmac.

Changes: v2 -> v3
 - Rebase against 7a5fa3dbe555794ce401a7435cb91f8695fc9847.

Changes: v1 -> v2
 - Added MASK_<INSN> for each instruction, as suggested.
 - Changed operand 'x' to operand 'X', as suggested.

This patch series presents the comprehensive implementation of the MAC and ALU
extension for CORE-V.

Tested with riscv-gnu-toolchain on binutils, ld, gas and gcc testsuites to
ensure its correctness and compatibility with the existing codebase.
However, your input, reviews, and suggestions are invaluable in making this
extension even more robust.

The CORE-V instructions are described in the specification [1] and work can be
found in the OpenHW group's Github repository [2].
