Hi, I'm currently trying to retarget the gcc backend to a VLIW architecture developed in my workgroup. This architecture has a branch delay slot, so i tried the following (according to http://gcc.gnu.org/onlinedocs/gccint/Delay-Slots.html):
(define_attr "type" "branch,other" (const_string "other")) (define_delay (eq_attr "type" "branch") [(eq_attr "type" "other") (nil) (nil)] ) (define_insn "call" [(call (match_operand:QI 0 "memory_operand" "") (match_operand:SI 1 "const_int_operand" ""))] "" "c7 brl %0" [(set_attr "type" "branch")] ) Unfortunately, the delay slot seems not to be used by the compiler. Even worse, there are no nops being emitted, which results in wrong asm code. Did I misunderstand something? Thanks for your help, Jan
