Subject: (movqi+2): Add address registers.
X-Git-Url: http://git.sourceforge.jp/view?a=commitdiff_plain;h=6dbf3211a5ccf0f29afa40a3e0f7026e894b977a;p=pf3gnuchains%2Fgcc-fork.git

(movqi+2): Add address registers.
(movxf+1): Disable for TARGET_5200.
(movxf+2): New pattern for TARGET_5200.
(addsi3): Add define_expand.  Move code to output_addsi3.
(addsi3_internal): Renamed from addsi3.  Disable for TARGET_5200.
(addsi3_5200): New pattern for TARGET_5200.
