 	src/tests/kernel/arch/mips: stack_pointer.h
 
 Log Message:
 t_signal_and_sp: mips: Fix {MISALIGN,FIX}_SP() for !o32
 
 Use `daddiu` instead of `addiu` as done in <mips/asm.h>.
 
 Otherwise, +/-1 is added to lower-32-bits of sp, and then
 results are sign-extended to whole-64-bits register (oops!!).
