G_BITCAST
^^^^^^^^^
Reinterpret a value as a new type. This is usually done without changing any
bits but this is not always the case due a sublety in the definition of the
:ref:`LLVM-IR Bitcast Instruction <i_bitcast>`.
Reinterpret a value as a new type. This is usually done without
changing any bits but this is not always the case due a sublety in the
definition of the :ref:`LLVM-IR Bitcast Instruction <i_bitcast>`. It
is allowed to bitcast between pointers with the same size, but
different address spaces.
