help
Allows turn on optimalized library function (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.

bool "Optimalized lib function ASM"
depends on OPT_LIB_FUNCTION && (XILINX_MICROBLAZE0_USE_BARREL = 1)
default n
help
Allows turn on optimalized library function (memcpy and memmove).
Function are written in asm code.
