hi i want create a commande line tool for arm64 et intel x86-64 Xcode 16 macbook pro M3 my setting : and but my application compile only for arm64 who can explain to me ?

hello, i wrote a method with Neon for accelerate my code.. I don't have the expected result only simples instructions and, or, shift... on 64bits no gain speed. nada :-( i dont understand... how programm this method for speed? original code : unsigned long long RXBitBoard::get_legal_moves(const unsigned long long p_discs, const unsigned long long o_discs) { const unsigned long long inner_o_discs = o_discs & 0x7E7E7E7E7E7E7E7EULL;

hi i dont know if i post in a good section. i have crash without message in console only error 34 311 what does this code mean? erreur -311 smFHBlkDispErr : an error occurred during _sDisposePtr (suppression du bloc FHeader). erreur -34 dskFulErr : full disk or is this something else? thank

I'm looking to do conditional programming with NEON. I try the __ARN_NEON tag. it doesn't work can you help me?

hello, I would like to run benchmarks on p-cores vs e-cores, I suspect a difference of more than 50% is it possible to choose your processor (P or E) to run your program? nice day

Hi, is there an intrinsic instruction to shift a vector from another a shift vector? thank

hi Question is in the title.. do we already know the length of the vectors? best regards

hello, i have this error : error: accessing build database "/Users/.../Build/Intermediates.noindex/XCBuildData/build.db": disk I/O error only if i use a custom paths for derived data... how to fix it

Do you know any software that indicates the frequency of the cores in real time? the macbook pro adapts the frequency of the cores according to the load/temperature it seems to me thank
