i386.c (print_operand): Handle new 'A' formatting code.
2000-10-23 Diego Novillo <dnovillo@cygnus.com>
* i386.c (print_operand): Handle new 'A' formatting code.
387 opcodes need suffixes even with -mintel-syntax.
Check for explicit size override (codes 'b', 'w' and 'k').
(print_operand_address): Check if register prefix is needed when
emitting `ds' segment override.
* i386.h: Add comment about new 'A' formatting code.
* i386.md (jump and call patterns): Emit absolute references using %A.
