It seems risc-v is missing the "small and big", "hardware accelerated", equilavent of x86 "rep stosX" and "rep movsX". Basically hardware memcpys and memsets. Heard latest arm ISA has them.
risc-v implementors/experts out there: is this true?
- childintime 4y agonot an expert, but it seems to me the vector extension should be able to do this.
- sylware 4y agoLike on ARM with neon and x86 with avx, but even on those, they got direct hardware acceleration without neon/avx of memcpys and memsets (big and small).
