🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)
Available on (x86 or x86-64) and target feature avx512dq and x86-64 only.
Expand description

Calculate the max, min, absolute max, or absolute min (depending on control in imm8) for the lower single-precision (32-bit) floating-point element in a and b, store the result in the lower element of dst, and copy the upper 3 packed elements from a to the upper elements of dst. Lower 2 bits of IMM8 specifies the operation control: 00 = min, 01 = max, 10 = absolute min, 11 = absolute max. Upper 2 bits of IMM8 specifies the sign control: 00 = sign from a, 01 = sign from compare result, 10 = clear sign bit, 11 = set sign bit. Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
