MSVC does not support inline assembly, which is used by the implementation of rte_atomic128_cmp_exchange and is needed by the C11 flavor of lib/stack.
A special implementation of rte_atomic128_cmp_exchange compatible with MSVC is added to rte_stack_lf_c11.h. It uses an intrinsic function when using MSVC, and inline assembly when other compilers are used. Existing atomic tests (which are not C11 compatible) are now skipped when using MSVC. v3: * Isolated the additional implementation of rte_atomic128_cmp_exchange to MSVC only. v2: * Added MSVC compatible implementation of rte_atomic128_cmp_exchange * Skipped non-C11 atomic tests when using MSVC Andre Muezerie (2): test: disable non-C11 atomic tests for MSVC stack: enable build with MSVC app/test/test_atomic.c | 2 ++ lib/stack/meson.build | 6 ------ lib/stack/rte_stack_lf_c11.h | 27 +++++++++++++++++++++++++++ 3 files changed, 29 insertions(+), 6 deletions(-) -- 2.47.2.vfs.0.1
