aarch64-elf to produce exe for gdb simulator

Hi

gdb has a simulator for aarch64 and libgloss has aarch64 support. Normally,
you just need "CPU-elf-gcc main.c -o main" to get a simple hello world that
will run on the gdb simulator.

Are there extra arguments required for the aarch64-elf target?

I assume this works and someone knows how to use it. :)

Thanks.
