Problem with Delayed Branch Scheduling

Hi everybody,

I have a problem with delayed branch scheduling. Problem in a DSP porting which has VLIW instructions and delayed branches. While scheduling delayed branches, GCC (3.4.3) schedules an instruction which is a part of a VLIW instruction. Is this the problem of the following define_delay description?

(define_delay (eq_attr "type" "jump")
  [(eq_attr "type" "!jump") (nil) (nil)
   (eq_attr "type" "!jump") (nil) (nil)])


Thanks in advance,
Balaji Sivan
