Why is this required on aarch64 but not all the other architectures?
I think it's because GCC rejects "-m64”.
That’s interesting. I thought -m<archbits> is some kind of common
flag that works on all architectures.
No, all the "-m" stuff is target-dependent.
Can someone verify this?
mustang-01:~ $ gcc -m64 hello.c
gcc: error: unrecognized command line option '-m64'
mustang-01:~ $ gcc --version
gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-16)
Also the man page lists -m64 under only specific targets.
