// RCPPS - Compute Reciprocals of Packed Single Precision Floating-Point Values
//
// RCPPS computes approximate reciprocals of 4 packed single-precision (32-bit) floating-point values
// Relative error: |Relative Error| <= 1.5 * 2^-12
//
// Special cases:
// - Source 0.0 returns infinity with sign of source
// - Denormal source treated as 0.0 (same sign)
// - SNaN converted to QNaN, QNaN returned as-is
// - Tiny results flushed to 0.0 with sign of operand
//
// Opcodes:
// NP 0F 53 /r             RCPPS xmm1, xmm2/m128     - Compute approximate reciprocals of packed single from xmm2/m128

const ALIGNED_ADDR: u64 = 0x3000; // 16-byte aligned address for testing
