label — LLVM 22.1.8 documentation

# 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 integer_number or an absolute_expression. The value must be in the range from -32768 to 65535.

- A 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:
