============
Branch Weight Metadata represents branch weights as its likeliness to be taken
(see :doc:`BlockFrequencyTerminology`). Metadata is assigned to the
``TerminatorInst`` as a ``MDNode`` of the ``MD_prof`` kind. The first operator
is always a ``MDString`` node with the string "branch_weights". Number of
operators depends on the terminator type.
(see :doc:`BlockFrequencyTerminology`). Metadata is assigned to an
``Instruction`` that is a terminator as a ``MDNode`` of the ``MD_prof`` kind.
The first operator is always a ``MDString`` node with the string
"branch_weights". Number of operators depends on the terminator type.
Branch weights might be fetch from the profiling file, or generated based on
`__builtin_expect`_ instruction.
