<p>This directive enables or disables all assembler transformation,
including relaxation (see <a href="Xtensa-Relaxation.html#Xtensa-Relaxation">Xtensa Relaxation</a>) and
optimization (see <a href="Xtensa-Optimizations.html#Xtensa-Optimizations">Xtensa Optimizations</a>).

<p>Transformations are enabled by default unless the &lsquo;<samp>--no-transform</samp>&rsquo;
option is used. The <code>transform</code> directive overrides the default
determined by the command-line options. An underscore opcode prefix,
disabling transformation of that opcode, always takes precedence over
both directives and command-line flags.
