Re: Modifying ARM code generator for elimination of 8bit writes - need help

There are other targets with targets specific options to work around this or

-mno-byte-writes and -mbyte-writes, with the latter being the default, be
unlikely to be acceptable? In particular, the MT port has these two options:

-mbacc
	Use byte loads and stores when generating code.

-mno-bacc
	Do not use byte loads and stores when generating code.
I was just about to ask about this very thing since I'm quite sure that there would be interest in adding this to devkitARM.

How much work would it be to implement these switches? I assume that the toolchain would need multilibs for these options in order to use newlib etc.
