Conditionally branches to one of several destination basic blocks based on a
8404-
value of builtin integer or function type. If the operand value matches one of the ``case``
8404+
value of builtin integer. If the operand value matches one of the ``case``
84058405
values of the instruction, control is transferred to the corresponding basic

block. If there is a ``default`` basic block, control is transferred to it if
84078407
the value does not match any of the ``case`` values. It is undefined behavior
