* ns32k_gen_operand is no longer needed. * new function symbolic_reference_mentioned_p (stolen from i386). * make print_operand dtrt when printing symbolic "constants" in picmode and abort for the cases that it can't handle (e.g. symbol+offset). ns32k.h: * Use NS32K_DISPLACEMENT_P wherever suitable. * make LEGITIMATE_PIC_OPERAND_P dtrt to make the ns32k_gen_operand hack unnecessary. ns32k.md: * Use general_operand instead of ns32k_gen_operand everywhere. * replace "rmn" by "g" again. * make addsi3 dtrt for pic. The comments in ns32k.md still need some updates. Thank's again to Ian Dall for his help.

; BUGS: ;; Insert no-op between an insn with memory read-write operands ;; following by a scale-indexing operation. ;; The Sequent assembler does not allow addresses to be used ;; except in insns which explicitly compute an effective address. ;; I.e., one cannot say "cmpd _p,@_x" ;; Implement unsigned multiplication??

;; We don't want to allow a constant operand for test insns because ;; (set (cc0) (const_int foo)) has no mode information. Such insns will ;; be folded while optimizing anyway. ;; ;; In order for pic mode to work we cannot generate, for example ;; ;; addd _x+5,r1 ;; ;; instead we must force gcc to generate something like ;; ;; addr 5(_x(sb)),r0 ;; addd r0,r1 ;; ;; This was done through operand constraints (using "rmn" in place of "g"), ;; but now we use a special predicate general_operand. This can safely ;; be used everywhere general_operand would otherwise be used except ;; in the "movsi" and the load/push address insn which know how to deal ;; with symbols. ;; (define_insn "tstsi" [(set (cc0) (match_operand:SI 0 "nonimmediate_operand" "rm"))] "" "* { cc_status.flags |= CC_REVERSED; operands[1] = const0_rtx; return "cmpqd %1,%0"; }")
