100% what the outcome will be (1).
* The retro-fitting cost onto existing implementations (even though the
specification has not been finalised) is negligeable
- (changes to words in the specification);
+ (changes to words in the specification)
* The benefits are clear (pain-free transition path for vendors to safely
upgrade over time; no fights over Custom opcode space; no hassle for
software toolchain; no hassle for GNU/Linux Distros)
* The implementation details are clear (and problem-free except for
vendors who insist on deploying dozens of conflicting Custom Extensions:
an extreme unlikely outlier).
+* Compliance Testing is straightforward and allows vendors to seek and
+ obtain *multiple* Compliance Certificates with past, present and future
+ variants of the RISC-V Standard (in the exact same processor), in order
+ support legacy customers and provide same customers with a way to avoid
+ "impossible-to-make" decisions that throw out ultra-expensive multi-decade
+ proprietary legacy software at the same as the hardware.
