Subject: [Bug target/16480] using -msdata causes internal compiler error
Date: Wed, 25 Aug 2004 11:21:00 -0000 [thread overview]
Message-ID: <20040825112125.4974.qmail@sourceware.org> (raw)

------- Additional Comments From amodra at bigpond dot net dot au 2004-08-25 11:21 -------
Mainline fails similarly. The failure results from this splitter
(define_split
[(set (match_operand:DI 0 "nonimmediate_operand" "")
(match_operand:DI 1 "input_operand" ""))]
"reload_completed && !TARGET_POWERPC64
&& gpr_or_gpr_p (operands[0], operands[1])"
[(pc)]
{ rs6000_split_multireg_move (operands[0], operands[1]); DONE; })
The "input_operand" predicate accepts any memory operand as the second operand.
rs6000_split_multireg_move thus needs to accept anything that we accept in
rs6000_legitimate_address. For this particular failure, that's a
(mem (symbol_ref (...))), which happens to satisfy legitimate_small_data_p.
