config OPT_LIB_FUNCTION
	bool "Optimized lib function"
	default y
	help
	  Turns on optimized library functions (memcpy and memmove).
	  They are optimized by using word alignment. This will work
	  fine if both source and destination are aligned on the same
	  boundary. However, if they are aligned on different boundaries
	  shifts will be necessary. This might result in bad performance
	  on MicroBlaze systems without a barrel shifter.

config OPT_LIB_ASM
	bool "Optimized lib function ASM"
	depends on OPT_LIB_FUNCTION && (XILINX_MICROBLAZE0_USE_BARREL = 1)
	depends on CPU_BIG_ENDIAN
	default n
	help
	  Turns on optimized library functions (memcpy and memmove).
	  They are written in assembly.
