.. _amdgpu_synid7_label:
label
===========================
A branch target which is a 16-bit signed integer treated as a PC-relative dword offset.
This operand may be specified as one of the following:
* An :ref:`integer_number<amdgpu_synid_integer_number>` or an :ref:`absolute_expression<amdgpu_synid_absolute_expression>`. The value must be in the range -32768..65535.
* A :ref:`symbol<amdgpu_synid_symbol>` (for example, a label) representing a relocatable address in the same compilation unit where it is referred from. The value is handled as a 16-bit PC-relative dword offset to be resolved by a linker.
Examples:
.. parsed-literal::
offset = 30
label_1:
label_2 = . + 4
s_branch 32
s_branch offset + 2
s_branch label_1
s_branch label_2
s_branch label_3
s_branch label_4
label_3 = label_2 + 4
label_4:
