This causes compile errors when it is enabled with RTE_ARM_USE_WFE. eg. ../lib/eal/arm/include/rte_pause_64.h: In function ‘rte_wait_until_equal_16’: ../lib/eal/include/rte_common.h:530:56: error: expression in static assertion is not constant 530 | #define RTE_BUILD_BUG_ON(condition) do { static_assert(!(condition), #condition); } while (0) | ^~~~~~~~~~~~ ../lib/eal/arm/include/rte_pause_64.h:156:9: note: in expansion of macro ‘RTE_BUILD_BUG_ON’ 156 | RTE_BUILD_BUG_ON(memorder != rte_memory_order_acquire && | ^~~~~~~~~~~~~~~~ Fix the compile errors by replacing the check with an assert, like in the generic implementation (lib/eal/include/generic/rte_pause.h).
