Subject: A question about if crti.s and crtn.s is not necessary?
Hi,
In LoongArch port, I found build musl and libc-test is OK without
crt/loongarch64/crti.s and crt/loongarch64/crtn.s,
so I want to ask if crti.s and crtn.s is not necessary in architecture?

The crt changes shouldn't be necessary at all huh? I didn't see any
custom asm
for riscv, for example.
