Is there a way to tell gcc to not generate the lwl, lwr instructions?Gcc will only ever generate these instructions when __attribute__((unaligned))

I got lwl and lwr from a memcpy() with two void pointers...
I quickly changed those to the (aligned) structure pointers instead, and then memcpy() changed to ordinary word loads and stores.
So, is somebody starting a toolchain for that new Chinese CPU? :-)
I don't hear about it,but it will happen soon or later:)
We work around lwl/lwr problem by modifying toolchain from H.J. Lu's rh port.
it seems that gcc will explicitly output lwl/lwr for unaligned block copy,in other cases it will generate
ulW macros for gas to handle.
