Shall we arrange the instructions to 2 groups (compressible and non-compressible), instead of crossing each other?

src/hotspot/cpu/riscv/c2_globals_riscv.hpp line 49:

It's best to keep InteriorEntryAlignment and CodeEntryAlignment unchanged if there's no obvious benefits.

These changes are made for shrinking the code size to a minimum level. Though regarding them doing no harm and as an enhancement, I consider it also great to remain them unchanged.

Need some testing work after the changes and if there are other suggestions I feel pleased to change.

It's better to move this comment before the if block which does compression.

maybe rename to "bool do_compress"?

Thanks for pointing out this and I have moved them before every if block. A trivial detail might be that we need to use `/**/` inside macros instead of `//`. Also fixed other comments.

This PR has the following changes:
1. Implement byte-reverse instruction `rev8` of RISC-V BitManipulation Extension.
2. Code improvement of existing byte reverse methods. 
3. Merge assembler_riscv_b.hpp and assembler_riscv_v.hpp into assembler_riscv.hpp

New C2 instructions under riscv_b.ad are covered by the following JTREG tests:
- test/hotspot/jtreg/compiler/codegen/Test6431242.java
- test/hotspot/jtreg/compiler/c2/TestCharShortByteSwap.java

Hotspot and jdk tier1 tests on QEMU (with and without UseRVB) are passed without new failures.

However, there are still some byte reverse operations that are not covered by spec, for example, "reverse bytes in halfword in lower 16 bits and sign extend". Base on the existing instructions naming style, we use `rev8.h.h` to represent it.

> This PR has the following changes:
> 1. Implement byte-reverse instruction `rev8` of RISC-V BitManipulation Extension.
> 2. Code improvement of existing byte reverse methods. 
> 3. Merge assembler_riscv_b.hpp and assembler_riscv_v.hpp into assembler_riscv.hpp
>

Looks like c_extract and c_sextract are not used?

maybe better to expand those macros directly?

Maybe rephrasing like this:
//   The offset encoding in jal ranges bits [12, 31] could span the cache line.

src/hotspot/cpu/riscv/riscv.ad line 1204:

Looks like this comment dupliates the one for CallStaticJavaDirectNode::compute_padding.

src/hotspot/cpu/riscv/vm_version_riscv.cpp line 109:

I think this should better to place this one after UseRVV and UseRVB.

Is it necessary to pass nmethod_barrier_guard_offset() as the "extra_offset" parameter here since this function will return (12 * instruction_size) which is multiple of 4 ?

src/hotspot/cpu/riscv/macroAssembler_riscv.cpp line 2954:

Same question: Is there a reason to pass "NativeCallTrampolineStub::data_offset" as the "extra_offset" parameter here since this function will return (3 * NativeInstruction::instruction_size) which is multiple of 4 ?

Thanks for pointing out this - this seems to be inherited from the original patch (the version that we decode instructions in `emit()`) and they seem to be not used anymore and I have removed them.

Unfortunately, this could not be easily done by substituting by a simple `assert_cond(!CHECK_RD || Rd != x0);` because of some details:
`c_ldsp` and `c_fldsp` use `Register` and `FloatRegister` separately so there is a type-related problem: x0 is only one `Register` and only `c_ldsp` needs this sanity check. So these macros here are trying to make sure this check isn't generated by `c_fldsp` at all because checking `Rd(a float register) != x0` will result in compilation errors.

Yes, I know the issue you are trying to resolve. Actually, I prefer to have two INSN macro definitions here: one for the integer case and one for the floating point case. That will be cleaner.

Yes - it seems a little obscure though.

1. The background is that:

about the `nmethod_entry_barrier`:

nmethod_entry_barrier (begin) {   <-  when we reach here, we may get a 2-byte alignment because of RVC's existence.
   ... 
   amoswap                            
   <the swapped address in the code segment>    <-  though the size of the whole stub is a multiple of 4 currently, 
                                                    here we may also get a 2-byte alignment because of the above issue.
} nmethod_entry_barrier (end)


and about the trampoline:

trampoline (begin) {  <-  when we reach here, we may get a 2-byte alignment because of RVC's existence.
   auipc
   ld
   jalr
   <the real jump target in the code segment>  <-  same as the above explanation.
} trampline (end)


2. The reason to pass another argument is that: 

we might consider just keeping the start address of the code slices (nmethod_entry_barrier and trampoline) aligned to 4-byte to solve this issue, but this assumption is based on 'the size of the code slices (nmethod_entry_barrier and trampoline themselves) are a multiple of 4', and we don't know if they will change in the future by RVC. So I explicitly pass the real target address to the `align` function as a new argument to make sure the code is always right in the future.

I am pleased with other suggestions for this part.

For the nmethod_entry_barrier case, I would omit the extra_offset parameter (and also the nmethod_barrier_guard_offset funtion). I think your newly-added assertion at line 265 is enough.

But looks like it's different in the trampoline case where I see we need a wordSize (8bytes) alignment. So we may keep the change for this case.

So I explicitly pass the real target address to the `align` function as a new argument to make sure the code is always right in the future.

Yes, I agree with your point. That trampoline part is special and requires to be scrupulous to make changes.

So maybe I'd better remove the `nmethod_barrier_guard_offset` part right?

Yes. Please also update the code comments. It looks strange to find those comments starts with a "RVC:".
Also we should make the exact alignment required explicit in comments like: "RISCV's amoswap instructions need an alignment for the memory address it swaps" or "RISCV CAS needs an alignment for memory", etc.

Is "shamt == 0" a common condition? Maybe it would be better to move it into the "else" branch.

I think it will be better to introduce one new immIScale which combines all three.
Then we can combine the newly-added instructs and reduce redundancy. If you do that, you will also need a new enc_class for distinguishing between the different Zba shift instruction encodings.

// Scale/Shift values for Zba instructions
operand immIScale()
%{
predicate(0 <= n->get_int() && (n->get_int() <= 3));
match(ConI);
op_cost(0);
format %{ %}
interface(CONST_INTER);
%}

`shamt == 0` is not a common case. I have moved it to else branch. Thank you for pointing it out :-)

Thank you for the suggestion. It's maybe better to call the `shadd` under macroAssembler (where t0 is actually not used) to avoid the reduction definition of enc_class. New commits pushed.

I have tested this patch under whole `test/jdk` and `test/hotspot/jtreg` folders without Monday's change through last weekend on a Hifive Unleashed and only revealed [JDK-8279664](https://bugs.openjdk.java.net/browse/JDK-8279664), which has nothing to do with this patch, for the [RISC-V backend initial-load patch](https://github.com/openjdk/riscv-port/commit/7148c39832fe522bad91df77ef4b5c9371193c35) could also reveal this problem on the Unleashed board I'm currently using. This one is a bit weird and I need more time to dig deep into that.

About Monday's incremental changesets I tested `test/hotspot/jtreg/compiler`, `test/hotspot/jtreg/gc/z`, and `test/hotspot/jtreg/gc/shenandoah` with or without RVC and revealed no errors. Also SPECjbb2015 is tested and the result seems to have no regression found under RVC - the result on Unleashed remains a `max-jOPs` level of score 370 with minor fluctuations.

I think maybe this patch could safely move forward -- except I need to take a look at JDK-8279664 to find whether it is a board-related issue because I cannot reproduce it on C910 and qemu. And thanks for the scrupulous reviews and the delicious suggestions, Felix and Yadong. :-)

What about codesize improvement of the C2 JIT code? BTW: You need to rebase the patch on the latest repo.

Thanks for the kind reminder - rebased and tested a simple `test/hotspot/jtreg/compiler` with/without RVC on qemu without errors found.

> What about codesize improvement of the C2 JIT code?
To be short and precise, currently just 'fair' but far from 'good', as the effect of [original patch](https://github.com/openjdk/riscv-port/pull/24). 

This patch only enables the basic definitions of RVC and some scattered usages in the dot ad file, so its title is just a very simple 'riscv: RVC support' and I didn't mention its effect. But considering currently register spills and `pusha/popa`s are covered by this patch, which could cover many instructions (C2 and some stub code), so the result is not 'poor' though.

With respect to this, I shall consider ways to further enable compressions for C1/C2's instructions to take it back to nearly a level of the original patch afterward by adding further patches.

Testing observed a few failures after JDK-8278387. On RISC-V, we followed JDK-8278489: The reason for the failures is in the native-wrappers, in the +UseHeavyMonitors paths, we don't preserve the result register after the native call.

Hotspot/jdk tier1 passed on the unmatched with -XX:+UseHeavyMonitors, and all jtregs were tested on Qemu without new failures.

Still some suggestions about the comments, otherwise looks good.

Hi team,

This is a preview fix for the JFR-related crash - maybe the comment in this patch should be polished.
TIL that complex problems often result from seemingly negligible changes :-)
I need to cautiously test this change, though it seems no harm, to guarantee that it is safe and to ensure the problem is gone so please stay a little tuned.

Thanks,
Xiaolin

@zhengxiaolinX Nice catch. In fact, we fixed a similar bug before, and unfortunately missed here.

Great catch. This aligns with function "enter()" which creates stack frames. Looks good.

src/hotspot/cpu/riscv/macroAssembler_riscv.hpp line 63:

I would suggest move this code comment before function "void enter()" in the same file.
Maybe rephrasing like this:
"SP must be updated to the right place before saving/restoring RA and FP because signal
 based thread suspend/resume could happen asynchronously."

I see JFR works quite stable with some non-trivial benchmark workload. So good to go. Thanks.

This fix is similar with JDK-8278417, which calls `generate_address` directly to generate address for array access.

All jtregs were tested on QEMU passed without new failures.

Some places are missed updating when refactoring riscv stack frame previously.

We need to update calculation of saved_fp for compiled frame in frame::safe_for_sender.

Previous riscv stack frame patch:
https://github.com/openjdk/jdk-sandbox/commit/db2415748747a0912749bb8fc160a8948021a924

All jtregs were tested on QEMU without new failures.

The same problem exists on the riscv platfom. So we follow https://bugs.openjdk.java.net/browse/JDK-8276563.

All instances of type Register exhibit UB in the form of wild pointer (including null pointer) dereferences. This isn't very hard to fix: we should make Registers pointer to something rather than aliases of small integers.

Hotspot/jdk tier1 were passed on the unmatched board. And all jtreg tests have been tested on Qemu without new failures.

Changes requested by fyang (Lead).

src/hotspot/cpu/riscv/assembler_riscv.hpp line 46:

> 44:     n_float_register_parameters_c = 8, // f10, f11, ... f17 (c_farg0, c_farg1, ... )

Could you please also fix this typo: "rj_rarg0" should be "j_rarg0"? Otherwise looks good. Thanks.

The riscv port should follow https://bugs.openjdk.java.net/browse/JDK-8248404, for the same reason of:

In many cases the RISCV64 back end uses long and unsigned long types. These types don't work on LLP64 systems (such as Windows) and should be replaced either by int64_t or jlong, as appropriate.


Hotspot/jdk tier1 passed on the unmatched board. And all jtreg tests have been tested on Qemu without new failures.
