RISC-V Compliance Testing: Software and Programmer View
Software and Programmer View for RISC-V Compliance Testing.
Software and programmer view
Software and Programmer View for RISC-V Compliance Testing is anchored on Compliance pass rate across implemented ISA profiles and extension-specific corner-case suites.. Convert observations into mechanism-backed decisions with explicit ownership.
Keep ISA profile, ABI, and extension assumptions explicit.
Validate runtime feature detection against hardware contract.
Correlate compiler output with microarchitectural counters.
Preserve deterministic trap and privilege behavior in all modes.
Decode contract
