From
https://gcc.gnu.org/onlinedocs/gcc-10.1.0/gcc/Standards.html#index-ffreestanding
:
"Most of the compiler support routines used by GCC are present in libgcc, but
there are a few exceptions. GCC requires the freestanding environment provide
memcpy, memmove, memset and memcmp. Finally, if __builtin_trap is used, and the
target does not implement the trap pattern, then GCC emits a call to abort.
