Subject: [PATCH v2] eal/arm: replace RTE_BUILD_BUG on non-constant
The ARM implementation of rte_pause uses RTE_BUILD_BUG_ON to check
memorder, which is not constant. 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).
Fixes: 875f350924b8 ("eal: add a new helper for wait until scheme")
