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:
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:
