lib/libthr/arch/riscv/include/pthread_md.h
64 ↗	(On Diff #12678)	Why `+ 0x10`?

unmagic 0x10, which is TP_OFFSET

lib/libthr/arch/riscv/include/pthread_md.h
65 ↗	(On Diff #12682)	it is TP_OFFSET (architecture specific)

lib/libthr/arch/riscv/include/pthread_md.h
65 ↗	(On Diff #12682)	Why is it needed? `rtld-elf` already takes the size of `struct tcb` into account.

lib/libthr/arch/riscv/include/pthread_md.h
65 ↗	(On Diff #12682)	So compiler expects that tp register points to the first static TLS block. In variant I it is located just after struct tcb. We do the same in lib/libc/riscv/gen/_set_tp.c
