Please don't top post.
Ok, so if we really want to change the code to be able to handle
!TARGET_WORDS_BIGENDIAN the whole notion of s->le_mode becomes flawed.
Instead, it should get renamed into needs_swab or needs_byteswap or
something along those lines. Then we can set it accordingly based on
msr_le and target configuration.
For the mem_helper.c changes, could you please explain why you have to
treat msr_le and needs_byteswap separately?
Thanks,
Alex
