In 64-bit mode, NASM will by default generate absolute addresses. The
\i\c{REL} keyword makes it produce \c{RIP}-relative addresses. Since
this is frequently the normally desired behaviour, see the \c{DEFAULT}
directive. The keyword \i\c{ABS} overrides \i\c{REL}.

Currently, the only \c{DEFAULT} that is settable is whether or not
registerless instructions in 64-bit mode are \c{RIP}-relative or not.
By default, they are absolute unless overridden with the \i\c{REL}
specifier. However, if \c{DEFAULT REL} is specified, \c{REL} is
default, unless overridden with the \c{ABS} specifier, \e{except when
used with an \c{FS} or \c{GS} segment override}. The special handling
of \c{FS} and \c{GS} overrides are due to the fact that these
