| | | | | | | | | __builtin_prefetch() Supporting _m_prefetchw() (officially part of 3DNOW) across various compilers and platforms turns out to be difficult. This change removes the explicit _m_prefetchw call aimed at MSVC compilers given that it causes issues in clang / chromium compilations.

* Separate DLL export/import for test helpers dll, and fix typo.Gravatar Mike Kruskal2023-01-25
| | | | | | | The DLL export issue isn't a problem currently, since we don't explicitly export any symbols from the test dll. This will be an issue in the future though. Additionally, there was a typo in absl_internal_test_dll_contains that caused abseil_test_dll to be empty (and therefore not create a lib file).
