Returning a negative value for a boolean function seem to have the

The diff of the .s file before and after the change (using cross
compilation) starts with:

440,441c440,441
< .L43:
< 	li 3,1	 # D.25775,

quoted

.L42:
	li 3,0	 # D.25775,

while if -EFAULT is replaced by true, the diff is empty.

Ah, that's rather unfortunate.

Can you post the full asm listing, for all three cases?

cheers
