Chengwen Feng 5aa9189d74 config/arm: fix SVE build with GCC 8.3 ... If the target machine has SVE feature (e.g. "-march=armv8.2-a+sve'), and the compiler is gcc-8.3, it will produce this error: In file included from lib/eal/common/eal_common_options.c:38: lib/eal/arm/include/rte_vect.h:13:10: fatal error: arm_sve.h: No such file or directory #include <arm_sve.h> ^~~~~~~~~~~ The root cause is that gcc-8.3 supports SVE (the macro __ARM_FEATURE_SVE was 1), but it doesn't support SVE ACLE [1]. The solution: a) Detect compiler whether support SVE ACLE, if support then define RTE_HAS_SVE_ACLE macro. b) Use the RTE_HAS_SVE_ACLE macro to include SVE header file. [1] ACLE: Arm C Language Extensions, the SVE ACLE header file is <arm_sve.h>, user should include it when writing ACLE SVE code.
