A potential workaround is to ensure that the streaming engine (SE) is set up to load more than 64-bits from the SE in a single access.
Description
When (1) the streaming engine (SE) is being actively used by the programmer, and (2) when the streaming engine (SE) is set up to access 64-bits or less, and (3) when the result of the SE load is used in a scalar (non-vector) operation, the compiler may generate an illegal instruction that causes the assembly to emit a fatal error message.
