Issue submission checklist

• I report the issue, it's not a question

• I checked the problem with documentation, FAQ, open issues,
  forum.opencv.org, Stack Overflow, etc and have not found any solution

• I updated to the latest OpenCV version and the issue is still there

• There is reproducer code and related data files: videos, images, onnx, etc

Fix ideas:

#ifdef _M_X64 // or another macro specific to x86/64
    #include <immintrin.h> // Include necessary headers for x86/64 intrinsics
    // Use _tzcnt_u32 for x86/64
    #define TZS_INTRINSIC _tzcnt_u32
#elif defined(__aarch64__) // Macro for ARM64 architecture
    static inline uint32_t TZS_INTRINSIC(uint32_t x) {
        return __builtin_ctz(x); // GCC/Clang intrinsic for count trailing zeros
    }
#else
    #error Unsupported architecture
#endif
uint32_t result = TZS_INTRINSIC(value);

Current work around:

Hello, I'm not friendly to "ARM64EC", so I'm sorry if I have mistake.
And I have no test environment about ARM64EC building.
If my patch works well, please could you response ? I'l create pull requests.

On OpenCV code, cnt is used only for zlib-ng and hal.

kmtr@kmtr-VMware-Virtual-Platform:~/work/opencv4/modules$ git reset --hard
HEAD is now at 15783d6598 Merge pull request #25792 from asmorkalov:as/HAL_fast_GaussianBlur
kmtr@kmtr-VMware-Virtual-Platform:~/work/opencv4/modules$ git grep tzcnt
core/include/opencv2/core/hal/intrin.hpp:    // clang-cl doesn't export _tzcnt_u32 for non BMI systems
core/include/opencv2/core/hal/intrin.hpp:    return _tzcnt_u32(value);

I think we have to add condition for ARM64EC to stop using _tzcnt_u32().

Microsoft document is https://learn.microsoft.com/en-us/cpp/preprocessor/predefined-macros?view=msvc-170

For ARM64EC target, "_M_ARM" and "_M_ARM64" is undefined. So OpenCV try to use _tzcnt_u32() like x86-64.

• _M_ARM Defined as the integer literal value 7 for compilations that target ARM processors. Undefined for ARM64, ARM64EC, and other targets.
• _M_ARM64 Defined as 1 for compilations that target ARM64. Otherwise, undefined.
• _M_ARM64EC Defined as 1 for compilations that target ARM64EC. Otherwise, undefined.

So I think we should add condition for M_ARM64 .

- #if (_MSC_VER < 1700) || defined(_M_ARM) || defined(_M_ARM64)
+ #if (_MSC_VER < 1700) || defined(_M_ARM) || defined(_M_ARM64) || defined(_M_ARM64EC)
      unsigned long index = 0;
      _BitScanForward(&index, value);
      return (unsigned int)index;

Yeah that should fix it!

Thank you for your report ! I'll change pull request status to remove draft !
