回复:[RISC-V] [tech-privileged] [RFC] Toolchain interface for privilege spec related stuff.


"戎杰杰
 

Hi Krste,

    Sounds good.
    
    Also we are talking with @Philipp about how to keep compatible with vector v0.7.1 on toolchain interface,
    we suggest that we prefer this method to control it, e.g. -march=rv64gcv0p7 to specify vector v0.7.1,
   
    i think it's more consistent also,
    whether we use the 'v' extension with version number rather than 'x' extension to implement the requirement ?

Yes, that was the plan,
