This will work 49 fine if both source and destination are aligned on the same 50 boundary. However, if they are aligned on different boundaries 51 shifts will be necessary. This might result in bad performance 52 on MicroBlaze systems without a barrel shifter. 53 54config OPT_LIB_ASM 55 bool "Optimalized lib function ASM" 56 depends on OPT_LIB_FUNCTION && (XILINX_MICROBLAZE0_USE_BARREL = 1) 57 default n 58 help 59 Allows turn on optimalized library function (memcpy and memmove). 60 Function are written in asm code. 61 62if PLATFORM_GENERIC=y 63 source "arch/microblaze/platform/generic/Kconfig.auto" 64endif 65 66endmenu 67
