2018-09-12Add and enable u32x4_extend_to_u64x2_high for aarch64 NEON intrinsics.Sirshak Das1-0/+6
This is the high version of extendto. This function accomplishes the same task as both shuffling and extending done by SSE intrinsics. This enables the NEON version for buffer indexes to buffer pointer translation.

2018-08-01Add support for shuffle vector intrinsic via Neon in ARMSirshak Das1-0/+16
This adds byte_swap (variant of shuffle) and shuffle vector intrinsic for ARM based on Neon, concuring with same signature as SSE vector intrinsic. Change-Id: I386fd2b1dcc83654e4ad9f90a6065d7736e4ce5c Signed-off-by: Sirshak Das <sirshak.das@arm.com>

2018-02-08add CLIB_HAVE_VEC128 with NEON intrinsics (VPP-1127)Gabriel Ganne1-0/+60
Enable CLIB_HAVE_VEC128 if both aarch64 and __ARM_NEON ie. armv8 only, not armv7 Add more neon compare intrinsics wrappers. I only add simple intrinsics wrappers. More complex ones can be added later as they are needed, with performance tests on the corresponding feature to back them up. Remove wrongly added 128bits definitions defined on both armv7 and armv8 without concern for NEON instructions presence. Notable correspondinf code activations: * MHEAP_FLAG_SMALL_OBJECT_CACHE in mheap.c * ip4 fib mtrie leaves access * enable ixge plugin compilation for aarch64 (conf still disables it by default) Change-Id: I99953823627bdff6f222d232c78aa7b655aaf77a Signed-off-by: Gabriel Ganne <gabriel.ganne@enea.com>
