Hi Noah,
Because various targets override it:
> find -name pthread_spin_lock.*
./nptl/pthread_spin_lock.c
./sysdeps/alpha/nptl/pthread_spin_lock.S
./sysdeps/powerpc/nptl/pthread_spin_lock.c
./sysdeps/i386/nptl/pthread_spin_lock.S
./sysdeps/sparc/sparc64/pthread_spin_lock.S
./sysdeps/sparc/sparc32/sparcv9/pthread_spin_lock.S
./sysdeps/sparc/sparc32/pthread_spin_lock.S
./sysdeps/x86_64/nptl/pthread_spin_lock.S
./sysdeps/ia64/nptl/pthread_spin_lock.c
./sysdeps/sh/nptl/pthread_spin_lock.c
Cheers,
Wilco
