__APPLE__ isn't defined so:

#  if (defined(__aarch64__) || defined(__arm64__) || defined(_M_ARM64) || defined(_M_ARM64EC)) \
   && !defined(__APPLE__) && XXH_SIZE_OPT <= 0
#   define XXH3_NEON_LANES 6
#  else
#   define XXH3_NEON_LANES XXH_ACC_NB
#  endif

Will go with XXH3_NEON_LANES 6 which isn't ideal. Not huge deal but does req user to set #define XXH3_NEON_LANES 8 before including and messes up the shared/static library versions.

Not sure if there is a define that can catch this but here are flags for clang15 and gcc12:

One Apple M1 Pro.

`__APPLE__` isn't defined so: ``` # if (defined(__aarch64__) || defined(__arm64__) || defined(_M_ARM64) || defined(_M_ARM64EC)) \ && !defined(__APPLE__) && XXH_SIZE_OPT <= 0 # define XXH3_NEON_LANES 6 # else # define XXH3_NEON_LANES XXH_ACC_NB # endif ``` Will go with `XXH3_NEON_LANES 6` which isn't ideal. Not huge deal but does req user to set `#define XXH3_NEON_LANES 8` before including and messes up the shared/static library versions. Not sure if there is a define that can catch this but here are flags for `clang15` and `gcc12`: One Apple M1 Pro. ``` $> ./clang15 -dM -E -march=native - #define _LP64 1 #define __AARCH64EL__ 1

There doesn't seem to be anything different in the defines from a standard aarch64-linux-gnu toolchain, so it is impossible to detect.

Also XXH3_NEON_LANES is entirely internal and won't affect ABI compatibility.

@easyaspi314 : is there anything worth addressing in this issue report ?
Or is it already taken care of in recent NEON code path updates ?

I stand by my last comment. There is no way to detect M1 tuning from preprocessor macros.

Also, from what I recall, 6 lanes on M1 is just a slight ~2% decrease and not some terrible performance nightmare.
