(GLOBAL:*:DATATYPE:MISMATCH)
Data type mismatches are detected by calculating a hash value of the data type signature and comparing that hash value: if the hash values are different, the type signatures must have been different too and an error is reported. Because the information about the full type signature at the sender is not available, it has to be deduced from the function call parameters and/or source code locations where the data is transmitted.
If the hash values are identical, then there is some small chance that the signatures were different although no error is reported. Because of the choice of a very advanced hash function this is very unlikely. This hash function can also be calculated more efficiently than traditional hash functions.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
