Yes, but inside immintrin.h there is a check.
At least that what I am seeing for gcc4.4.3:

#ifdef __AVX__
#include 
#endif

Isn't it the same for your case?

If macro __AVX__ not defined, then 
#if defined(__AVX__)
would always be false and SCHED_VECTOR_ENABLE also wouldn't be defined.
So still don't understand why that is a problem

[dpdk-dev] [PATCH] lib/librte_sched: Fix compile with gcc 4.3.4

2015-11-27 Thread Qiu, Michael
I just replied that Marco AVX only exist in gcc version < 4.4 , otherwise it 
will not exist.

What's your suggest will not work if gcc version greater than 4.3.

So still need to check gcc version. Any other solution?

Thanks,
Michael

If you look at lib/librte_eal/common/include/arch/x86/rte_vect.h, you'll see 
the code similar
to one you are trying to put into rte_shed.c:

lib/librte_eal/common/include/arch/x86/rte_vect.h:
...
#if (defined(__ICC) || (__GNUC__ == 4 &&  __GNUC_MINOR__ < 4))

#ifdef __SSE__
#include 
#endif

#ifdef __SSE2__
#include 
#endif

#ifdef __SSE3__
#include 
#endif

#if defined(__SSE4_2__) || defined(__SSE4_1__)
#include 
#endif

#if defined(__AVX__)
#include 
#endif

#else

#include 

#endif
...

So I think you can do just like that:

#include 
#if defined(__AVX__)
#define SCHED_VECTOR_ENABLE
#endif

inside rte_sched.c

really?I don't think so.

AVX Marco only exist in the gcc version below 4.4,  I still need to check if 
below or beyond 4.4 am I right?

It's not exclusive.
You can include rte_vect.h and check AVX to define SCHED_VECTOR_ENABLE.

As I know here it needs a flag to identify whether the platform support
AVX, if not it will not use it, so I don't know if we could only simply
include rte_vect.h?

This kind of complication is managed by EAL.
I think we should include rte_vect.h.

gcc 4.3.4 does not include "immintrin.h", and will post below error:
lib/librte_sched/rte_sched.c:56:23: error:
immintrin.h: No such file or directory

To avoid this issue, a gcc version check is need and a flag to indicate
vector ablility.
