Hi, experts:
Would any expert fix this question?
It seems related MOVW instruction's usuage when turning off gcc

If i just turned on "-O1" or "-O2", still failed to compile uboot code.
Best wishes,

I disagree here. If you are hunting down a problem, you want to be as
close at the original code as possible. Disabling optimization is
such a dramatic ch

Don't do it, then.
Q: why would you want to switch off optimization? That's almost
