    opcodes: Make flushing denormals the default behavior · 631d097e

    Flushing denormals is a better default behavior for SIMD
    engines, since they tend handle denormals slowly (SSE,
    Altivec) or not at all (NEON).  Unfortunately, that
    behavior is expensive to emulate on IEEE-compliant FPUs,
    since you need to check for denormal before and after
    every operation.  At this point, the emulator flushes
    denormals and C code does not.
