Re: Views on bare metal port

[ardi <ardillasdelmonte@gmail.com>]

Hi,

I'm also in need of a libc whose syscall interface was easily
hook-able. Not knowing of any libc that has all the syscalls clearly
encapsulated (and encapsulated at the C level rather than at assembly
level), but considering the clean design of musl, I've chosen musl as
probably the best option. You can check the thread I started in the
list last Christmas: http://www.openwall.com/lists/musl/2017/12/21/3
