<p>The ‘<samp>--insn32</samp>’ and ‘<samp>--no-insn32</samp>’ 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 ‘<samp>--insn32</samp>’ is
|
||
|
|
used, then the linker only uses 32-bit instruction encodings. By default
|
||
|
|
or if ‘<samp>--no-insn32</samp>’ is used, all instruction encodings are used,
|
||
|
|
including 16-bit ones where possible.

|

|
<p>The ‘<samp>--ignore-branch-isa</samp>’ and ‘<samp>--no-ignore-branch-isa</samp>’ options
|
||
|
|
control branch relocation checks for invalid ISA mode transitions. If
|
||
|
|
‘<samp>--ignore-branch-isa</samp>’ 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 ‘<samp>--no-ignore-branch-isa</samp>’ is used a check is made causing
|
||
|
|
the loss of an ISA mode transition to produce an error.
