// This hack only updates the Status Flag on blocks that will read it.
// Most blocks do not read status flags, so this is a big speedup.
// Min/Max Speed Hack
#define CHECK_VU_MINMAXHACK 0 //(EmuConfig.Speedhacks.vuMinMax)
// This hack uses SSE min/max instructions instead of emulated "logical min/max"
// The PS2 does not consider denormals as zero on the mini/max opcodes.
// This speedup is minor, but on AMD X2 CPUs it can be a 1~3% speedup
