[RISCV] Mono RISC-V porting progress tracing

[Xinlong-Wu]

Current porting status

Mono RISCV currently has implemented some basic instruction generation, stack allocation, and error handling. It can run some of the programs located in dotnet/samples. The list of runnable programs can be found at https://github.com/Xinlong-Wu/runtime/blob/riscv-jit-rv64/RISCV64-PORTING.md

The pr's that have been merged so far (2023/12/08) are:

• [RISC-V] Port Mono for RISC-V 64 Arch (1/3) lp64d ABI #83714
• [RISC-V] Port Mono for RISC-V 64 Arch (2/3) thunk & tramponlie #83715
• [RISC-V] Port Mono for RISC-V 64 Arch (3/3) IL Lowering & Outputting #83716
• [mono] [RISC-V] re-implement floating point arithmetic without r4fp #84470
• [Mono][RISC-V] emit mul inst instead of emulated mul #85445
• [Mono] [RISCV] Fix abi issues (Monthly pr) #88649
• [RISCV] Store 2*XLEN ValueType half in Reg and half on stack when only A7 available #90072
• [RISC-V] Fix the order of parameters stored on the stack #96106

Futhure

• Pass all regression tests as far as possible for robust CI testing
• Mono RISC-V is currently focused on implementing the riscv64imadf extension. Trying to sound instruction generation under different extensions.
• Optmise generated code by Peephole Optimization， support C ext
• implement vector intrinsic
• Mono RISCV can be installed by dotnet-install.sh
• Native compile Mono RISCV and library at RISC-V computer
• Running graphical programs on RISC-V, i.e. Stardew Valley

Hi,

Thank for your work.
And if you need any test im available.
Also I propose to provide riscv64 servers if necessary.

Best Regards

If you might find it useful, I were able to build .NET SDK for riscv64 architecture: https://github.com/dkurt/dotnet_riscv

Excellent, I just downloaded it and tried to use it, found some problems, created a issue dkurt/dotnet_riscv#4
