WrapAPSIntResult()

template<typename T>

DataStackElement lldb_private::FormatterBytecode::WrapAPSIntResult ( T result, unsigned bit_width, bool is_unsigned )

static

Wrap the result of a binary operator applied to two APSInts back into a DataStackElement.

Comparison operators yield bool and need bit_width/ is_unsigned to construct the boolean's APSInt representation; arithmetic operators already yield a correctly-tagged APSInt and ignore them.
