      sse: handle NANs and denormals · b3517a4d
      David Schleef authored
      Set the DAZ and FTZ flags in the MXCSR, to set proper
      denormal behavior.  Implement NAN handling for maxf and
      minf.

      opcodes: Make flushing denormals the default behavior · 631d097e
      David Schleef authored
      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.
