Pull Request Overview
This PR enables constant Common Subexpression Elimination (CSE) optimization for the RISC-V64 architecture, bringing it to parity with ARM/ARM64 platforms. The optimization reduces redundant instruction sequences when loading large constants that are used multiple times.
- Extends constant CSE support from ARM/ARM64 to also include RISCV64
- Adds cost estimation logic for RISC-V64 immediate value loading in the JIT compiler
- Updates configuration constants and conditional compilation blocks to include TARGET_RISCV64

| File | Description |
|---|---|
| src/coreclr/jit/optcse.cpp | Updates conditional compilation blocks and function logic to enable constant CSE for RISCV64 alongside ARM architectures |
| src/coreclr/jit/jitconfigvalues.h | Renames configuration constants from ARM-specific to ARM_RISCV64 to reflect the expanded platform support |
| src/coreclr/jit/gentree.cpp | Adds comprehensive cost estimation logic for RISC-V64 constant loading by duplicating the algorithm from emitter::emitLoadImmediate |
| src/coreclr/jit/emitriscv64.cpp | Fixes spelling error in comment ("zeroes" → "zeros") |
* Adjust costSz and costEx for GT_CNS_INT node * Add riscv64 in const CSE jitconfigvalues

Is this something which is fixed by @tomeksowi's #119203? Could you run combined diffs (after merging his branch into yours)? |

It is not clear that it's fixed after merging. The regression gets worse after the merge than before. I suspect the cause might be due to differences in environment variables, but I'm not really sure about it. The regression actually improved than the base(pc-rel-pointers) after merging it with this PR(hoist-loop), so I think the regressions were not caused by this PR. Diffs running on the base branch (pc-rel-pointers)Diffs are based on 12,996 contexts (338 MinOpts, 12,658 FullOpts).

The reason may be that when generating asm diffs, nearly all pointers end up out of range because we're in PMI replay. I remember having to force |

I finally figured out the reason why absolute addresses are being generated for constants transformed by CSE. In the baseline JIT, the address calculation node N006(CNS_INT) is marked as contained and emitted via In contrast, in the diff JIT, constant CSE transforms this into N005(CNS_INT) and N007(STORE_LCL_VAR). Since N005 isn't marked as contained and I'm working on adding support for pc-relative addressing in Baseline JIT Diff JIT |

PC-relative CNS_INT emission improves duplicated block-local constants, but hoisting loop-invariant constants into locals can increase callee-saved pressure and regress small loops. We likely need a heuristic to avoid hoisting when it forces additional public static void MulOverflow()

I've added a heuristic to prevent hoisting the constants that would likely end up in callee-saved registers. Regressions due to the hoisted constants are now removed. diffsDiffs are based on 133,433 contexts (104,312 MinOpts, 29,121 FullOpts).

Removed bloated code generation for CALLs by disabling constant CSE for operands of FIELD_LISTs. Later, it might be better to improve constant folding to fold LCL_VARs defined as CNS_INT as a more general solution. DiffsDiffs are based on 133,433 contexts (104,312 MinOpts, 29,121 FullOpts).

@namu-lee, (in case you didn't knew) the CI merges dotnet/runtime's main branch to PR branch after the checkout. So it's better to use the same approach for diff computation/analysis and merge upstream main in your branch from time to time for clean diffs. e.g. Zbs changes were merged a few hours ago in main which may impact your results. You can use the button on UI: 
Another option is use main merge point of main in your branch as a base for jit-diff etc. |

Thank you for the information. I was actually using the latest merge point of main in my branch as the baseline for asmdiffs. I didn't realize that #115335 (Zbs) has been merged, so I will re-analyze the diffs after merging the upstream to see if there is any interaction with this PR. |

Re-analyzed diffs after merging the upstream branch. No significant changes found. Diffs are based on 125,653 contexts (103,293 MinOpts, 22,360 FullOpts). Overall (-313,464 bytes)
MinOpts (-211,776 bytes)
FullOpts (-101,688 bytes)

There was a problem hiding this comment.
Looks good, the remaining inefficiencies are few enough to make this PR worth it.
If you're looking for further optimization ideas in this area, separating auipc so the page offset can be reused by many I- or S-type instructions, but this would require changing the recorded relocations to something closer to the native ELF, which is a bigger change.
That may be similar to ARM64_PAGEBASE_REL21, ARM64_PAGEOFFSET_12A which does have an implementation in .NET.

Constant CSE is not enabled by default in RISCV64.
Enabling the constant CSE hoists the instructions used to load large, but repeatedly used constants so they can be shared.
Since generating a large constant requires at least 3 instructions in RISCV64, enabling constant CSE suppresses the emission of several redundant instruction sequences which would otherwise generate the same large constant.
