<p>The &lsquo;<samp>--insn32</samp>&rsquo; and &lsquo;<samp>--no-insn32</samp>&rsquo; options control the choice of
microMIPS instructions used in code generated by the linker, such as that
in the PLT or lazy binding stubs, or in relaxation.  If &lsquo;<samp>--insn32</samp>&rsquo; is
used, then the linker only uses 32-bit instruction encodings.  By default
or if &lsquo;<samp>--no-insn32</samp>&rsquo; is used, all instruction encodings are used,
including 16-bit ones where possible.

<p>The &lsquo;<samp>--ignore-branch-isa</samp>&rsquo; and &lsquo;<samp>--no-ignore-branch-isa</samp>&rsquo; options
control branch relocation checks for invalid ISA mode transitions.  If
&lsquo;<samp>--ignore-branch-isa</samp>&rsquo; is used, then the linker accepts any branch
relocations and any ISA mode transition required is lost in relocation
calculation, except for some cases of <code>BAL</code> instructions which meet
relaxation conditions and are converted to equivalent <code>JALX</code>
instructions as the associated relocation is calculated.  By default
or if &lsquo;<samp>--no-ignore-branch-isa</samp>&rsquo; is used a check is made causing
the loss of an ISA mode transition to produce an error.
