Previously, when writing a BufferStore statement in TVMScript, dtype
mismatch will not be detected but silently allowed.
For example, in the snippet below:
even if the elements of
buffer
is floating point numbers, while RHSis a handle, there is no mechanism to warn, fix, or error out.
This PR introduces auto casting mechanism in TVMScript to ensure that
the dtype of RHS matches LHS. When there is possible precision loss, it
will emit a warning so that the users could adjust accordingly.
