Currently, the SVE code is compiled only when -march supports SVE
(e.g. '-march=armv8.2a+sve'), there maybe some problem[1] with this
approach.

The solution:
a. If the minimum instruction set support SVE then compiles it.
b. Else if the compiler support SVE then compiles it.
c. Otherwise don't compile it.

Why is the CC_SVE_SUPPORT flag needed? The compiler has __ARM_FEATURE_SVE flag already which gets defined when '+sve" is added to '-march'.

I think this check and the above check do the same thing. i.e. both of them check if +sve flag is passed to the compiler.

I do not understand the need of this block of code, appreciate if you could explain why this is required.

The CC_SVE_SUPPORT is used to implement the hns3_get_sve_support API (below),
this API located in another file which is hns3_rxtx.c, and this file was
compiled with default machine_args.

	static bool
	hns3_get_sve_support(void)
	{
	#if defined(CC_SVE_SUPPORT)
		if (rte_vect_get_max_simd_bitwidth() < RTE_VECT_SIMD_256)
			return false;
		if (rte_cpu_get_flag_enabled(RTE_CPUFLAG_SVE))
			return true;
	#endif
		return false;
	}

If the machine_args doesn't support SVE but compiler support, we will compile
SVE code too, so in this case we need define CC_SVE_SUPPORT, so that in runtime
we could try judge whether support SVE. In this case, __ARM_FEATURE_SVE was not
defined because it is in hns3_rxtx.c which use default machine_args.

If the machine_args supports SVE we sure compile SVE code, in this case, to
maintain consistency, we also define this macro.

This is typical usage for compiling some soure file with custom flags (here is '-march=armv8.2-a+sve')
Please ref [1] with keyword 'extract_objects'

This is similar to what we do for AVX on x86. The first check is indeed
checking that +sve is passed to the compiler, but the second is different,
and checks whether it is possible for the flag to be passed to the
compiler. This second info then allows a separate C file to be compiled for
that extra instruction set, and then have the functions in it run-time
selected.
