DPCT1098 for store operations ?

[jinz2014]

I think the description in DPCT1098 may be confusing for the store operations:
__stcg

__stcs

__stwb

__stwt

Thanks for your clarification.

@jinz2014
The content of the DPCT1098 msg is The <expression text> expression is used instead of the <function name> call. These two expressions do not provide the exact same functionality. Check the generated code for potential precision and/or performance issues.
For more details, pls refer to https://www.intel.com/content/www/us/en/docs/dpcpp-compatibility-tool/developer-guide-reference/2024-1/dpct1098.html.

So, I'm not sure which part of the message is confusing. Could you provide more information?

For the load operations, the link indicates that we may change the codes generated by SYClomatic. For the store operations, we don't need to make further changes. Is that right ?

@jinz2014 The current migration mapping has the same semantics as the CUDA side. While the implementation of the CUDA side leverages cache operations, it has performance advantages; the SYCL side may not use cache operations.
