Sorry, the testcase is proprietary.  I'll provide a "recreated" one when 
submitting the patch.

Strictly speaking, I don't think so.  Take a look at the second line in the 
document, I see no mention of arrays.

Now if you're saying that mips-abi.html should be fixed to use the same 
wording as the header of mips_return_in_msb, it's fine with me.  I only 
wanted someone to decide which one should be corrected.

Agreed.


Thanks for your answer.
