Compiler Warning (level 1) C4556

value of intrinsic immediate argument 'value' is out of range 'lower_bound - upper_bound'

Remarks

An intrinsic matches a hardware instruction. The hardware instruction has a fixed number of bits to encode the constant. If value is out of range, it will not encode properly. The compiler truncates the extra bits.

Example

The following example generates C4556:

// C4556.cpp
// compile with: /W1
// processor: x86
#include <xmmintrin.h>

int main()
{
    __m64 m = _mm_setzero_si64();
    _m_pextrw(m, 5);   // C4556
    _mm_empty();
}
