<dl><dt><code>-relax-section</code><dd>Replace identified out-of-range branches with PC-relative <code>jmp</code>

sequences when possible. The generated code sequences are suitable
|

|
for use in position-independent code, but there is a practical limit
|
||
|
|
on the extended branch range because of the length of the sequences.

This option is the default.

and all call instructions with <code>jmp</code> and <code>callr</code> sequences

(respectively). This option generates absolute relocations against the

target symbols and is not appropriate for position-independent code.

an error message if an attempt is made to assemble an instruction which
