*** WAIT FOR SPECIFICATION FREEZE ***
This is an implementation for unratified and unfrozen RISC-V extension
and not intended to be merged as of now.
The only intent to submit this patchset is to test new instructions for
your (possibly virtual) environment and early review for fast adoption
after ratification.


This patchset adds following unratified extension to GNU Binutils:

-   Zihintntl (Non-Temporal Locality Hints extension)
    version 0.2 (may change on ratification)

... which adds only HINT instructions.

This is based on the ISA Manual, draft-20220707-f518c25:
<https://github.com/riscv/riscv-isa-manual/releases/tag/draft-20220707-f518c25>


[RFC: Automatic Instruction Compression]

NTL instructions are auto-compressed.  If NTL.* instruction is used and
'C' extension is enabled, it would be emit as 'C.NTL.*' instruction.

I think this behavior is harmless (and desired) considering the
specification but this behavior would be the first for HINT instruction.

[DO NOT MERGE]
Until 'Zihintntl' extension is ratified and final version number is
determined, this patch should not merged upstream.  This commit uses
unratified version 0.2 as in documentation (instead of possible 1.0
after ratification).

This commit adds 'Zihintntl' extension and its hint instructions.

bfd/ChangeLog:

	* elfxx-riscv.c (riscv_supported_std_z_ext): Add 'Zihintntl'
	standard hint 'Z' extension. (riscv_multi_subset_supports): Add
	handling for new instruction classes.

include/ChangeLog:

	* opcode/riscv.h (enum riscv_insn_class): Add new instruction
	classes: INSN_CLASS_ZIHINTNTL and INSN_CLASS_ZIHINTNTL_AND_C.
	(MASK_NTL_P1, MATCH_NTL_P1, MASK_NTL_PALL,
	MATCH_NTL_PALL, MASK_NTL_S1, MATCH_NTL_S1, MASK_NTL_ALL,
	MATCH_NTL_ALL, MASK_C_NTL_P1, MATCH_C_NTL_P1, MASK_C_NTL_PALL,
	MATCH_C_NTL_PALL, MASK_C_NTL_S1, MATCH_C_NTL_S1, MASK_C_NTL_ALL,
	MATCH_C_NTL_ALL): New macros.

opcodes/ChangeLog:

	* riscv-opc.c (riscv_opcodes): Add non-temporal locality hint
	instructions and aliases.

	instructions.
	* testsuite/gas/riscv/zihintntl-c.d: Likewise.
	* testsuite/gas/riscv/zihintntl-c-noalias.d: Likewise but
	different output with -Mno-aliases.
	* testsuite/gas/riscv/zihintntl-base.s: New test for base
	instructions corresponding non-temporal locality hints.
	* testsuite/gas/riscv/zihintntl-base.d: Likewise.
	* testsuite/gas/riscv/zihintntl-base-noarch.d: Likewise but
	without 'Zihintntl' extension in -march.

*** WAIT FOR SPECIFICATION FREEZE ***
This is an implementation for unratified and unfrozen RISC-V extension
and not intended to be merged as of now.
The only intent to submit this patchset is to test new instructions for
your (possibly virtual) environment and early review for fast adoption
after ratification.


[Cover Letter: Common in 'Zihintntl' and 'Zfa' patchsets]

As someone (I can't remember) pointed out in the RISC-V BoF of GNU Tools
Cauldron 2022, we don't have a policy to accept unstable extensions yet.
Still, at least we can talk about new extensions now...

1.  To try new instructions/features as fast as possible,
2.  To make actual adoption as fast as possible and
3.  To avoid redoing someone else's work

I'm working on following unratified RISC-V extensions:

1.  'Zihintntl' [resent as v2]
    <https://github.com/a4lg/binutils-gdb/wiki/riscv_zihintntl>
    <https://sourceware.org/pipermail/binutils/2022-July/121682.html>
2.  'Smrnmi' (resumable NMI)
    <https://github.com/a4lg/binutils-gdb/wiki/riscv_smrnmi>
    <https://sourceware.org/pipermail/binutils/2022-July/121689.html>
3.  'Zfa' [NEW]
    <https://github.com/a4lg/binutils-gdb/wiki/riscv_zfa>

I will resend 'Zihintntl' (squashed and applied minor formatting fixes)
and submit new 'Zfa' extension as a remainder of what am I doing.



['Zihintntl': Non-Temporal Locality Hints, Version 0.2]

This patchset adds following unratified extension to GNU Binutils:

-   Zihintntl (Non-Temporal Locality Hints extension)
    version 0.2 (may change on ratification)

... which adds only HINT instructions.

This is based on:
<https://github.com/riscv/riscv-isa-manual/commit/c0db46f72a1cc409194bf7f11c09e69a387f16a0>
(latest commit of the 'master' branch as of this writing)


Changes: v1 -> v2
-   Squashed
-   Fixed minor formatting errors
-   Added DECLARE_INSN declarations


Thanks,
Tsukasa

[DO NOT MERGE]
Until 'Zihintntl' extension is ratified and final version number is
determined, this patch should not merged upstream.  This commit uses
unratified version 0.2 as in documentation (instead of possible 1.0
after ratification).

This commit adds 'Zihintntl' extension and its hint instructions.

This is based on:
<https://github.com/riscv/riscv-isa-manual/commit/c0db46f72a1cc409194bf7f11c09e69a387f16a0>
(latest commit of the 'master' branch as of this writing)

bfd/ChangeLog:

	* elfxx-riscv.c (riscv_supported_std_z_ext): Add 'Zihintntl'
	standard hint 'Z' extension. (riscv_multi_subset_supports): Add
	handling for new instruction classes.

gas/ChangeLog:

	* testsuite/gas/riscv/zihintntl.s: New test for 4-byte hint
	instructions.
	* testsuite/gas/riscv/zihintntl.d: Likewise.
	* testsuite/gas/riscv/zihintntl-auto-c.d: Likewise but test auto
	compression to 2-byte instructions.
	* testsuite/gas/riscv/zihintntl-c.s: New test for 2-byte hint
	instructions.
	* testsuite/gas/riscv/zihintntl-c.d: Likewise.
	* testsuite/gas/riscv/zihintntl-c-noalias.d: Likewise but
	different output with -Mno-aliases.
	* testsuite/gas/riscv/zihintntl-base.s: New test for base
	instructions corresponding non-temporal locality hints.
	* testsuite/gas/riscv/zihintntl-base.d: Likewise.
	* testsuite/gas/riscv/zihintntl-base-noarch.d: Likewise but
	without 'Zihintntl' extension in -march.

include/ChangeLog:

	* opcode/riscv.h (enum riscv_insn_class): Add new instruction
	classes: INSN_CLASS_ZIHINTNTL and INSN_CLASS_ZIHINTNTL_AND_C.
	(MASK_NTL_P1, MATCH_NTL_P1, MASK_NTL_PALL,
	MATCH_NTL_PALL, MASK_NTL_S1, MATCH_NTL_S1, MASK_NTL_ALL,
	MATCH_NTL_ALL, MASK_C_NTL_P1, MATCH_C_NTL_P1, MASK_C_NTL_PALL,
	MATCH_C_NTL_PALL, MASK_C_NTL_S1, MATCH_C_NTL_S1, MASK_C_NTL_ALL,
	MATCH_C_NTL_ALL): New macros.

opcodes/ChangeLog:

	* riscv-opc.c (riscv_opcodes): Add non-temporal locality hint
	instructions and aliases.
