question about intrinsic naming

[PPParticle]

i don't understand the reason why all intrinsic apis are added "__riscv" prefix. Typing more letters seems more troublesome for programmers.

Also, i think previous naming rule is clear and easy to understand.

Primarily for the same reason C++ has namespaces. Adding the "__riscv" makes it less likely to collide with user variable names or names from other libraries a user might be using.
