The return value `res` is stored directly in $a0, which may reduce the need to `move` the `res` value to $a0. ================ Comment at: compiler-rt/lib/sanitizer_common/sanitizer_linux.cpp:1543 + "r"(__fn), "r"(__arg), "r"(nr_clone), "i"(__NR_exit) + : "memory"); + return res; ---------------- SixWeining wrote: > Shall we list $t0-$t8 here?

Yeah. ================ Comment at: compiler-rt/test/sanitizer_common/print_address.h:12 + defined(__s390x__) || (defined(__riscv) && __riscv_xlen == 64) || \ + defined(__loongarch__) // On FreeBSD, the %p conversion specifier works as 0x%x and thus does not ---------------- xry111 wrote: > SixWeining wrote: > > Should be __loongarch64? > `__loongarch64` is deprecated, use `__loongarch_lp64` instead. > `__loongarch64` is deprecated, use `__loongarch_lp64` instead. Okay, use __loongarch_lp64 instead.
