Subject: [PATCH] c4x.md: (in_annul_slot_3): Allow unarycc and binarycc
operations in 3rd annulled delay slot.
* config/c4x/c4x.md: (in_annul_slot_3): Allow unarycc and binarycc
operations in 3rd annulled delay slot.
(*lshrqi3_const_set): Disallow c constraint for operand0.
(modhi3+1, modhi3+2): Set attribute type to multi.
* config/c4x/c4x.c (c4x_S_constraint): Removed space in middle of
!= operator.
