To be clear, RTH's optimized functions aren't in glibc yet.  So, if you 
find they'd be better for RISC-V than the current generic functions, you 
should join in the process of getting them in glibc - for 2.28 not 2.27 
now, of course (but only if generic functions can't be made good for 
RISC-V would RISC-V-specific ones be desirable).
