RISC-V Assembly

Purpose

Guide agents through RISC-V assembly programming: RV32/RV64 instruction sets, register naming and calling conventions (psABI), ISA extension naming, inline assembly with GCC/Clang, compressed (RVC) instructions, and QEMU-based simulation with GDB remote debugging.

Triggers

• "How do I write RISC-V assembly?"
• "What are the RISC-V calling convention registers?"
• "How do I use inline asm for RISC-V in C?"
• "What do RISC-V extension letters mean (IMAFD)?"
• "How do I simulate RISC-V with QEMU?"
• "How do I debug RISC-V code with GDB?"

Workflow

1. Register file and calling convention
