Like you said i tried to split the move_immediate pattern after
reload. This is how i did this :
(define_split

'liu' will load the immediate value into the upper byte of the
specified register. The lower byte of the register is unaffected.
The liu pattern should be something like
(set (regX) (ior:HI (and:HI (regX) (const_int 255)) (const_int Y)))

Hello all,
It is not necessary that a pattern with a single constrain will have
only one instruction in the template.
Say if the pattern A have two instructions in the template and pattern
B has one instruction in the template and the target has only two
delay slots will i be able to tell gcc

So we can have something like this
(define_attr slottable no,yes,has_slot (const_string yes))
(define_delay
