2006-08-04 Dwarakanath Rajagopal <dwarak.rajagopal@amd.com>
* i386-dis.c (MXC,EMC): Define.
(OP_MXC): New function to handle cvt* (convert instructions) between
%xmm and %mm register correctly.
(OP_EMC): ditto.
(prefix_user_table): Modified cvtpi2pd,cvtpd2pi and cvttpd2pi
instruction operands in PREGRP2,PREGRP3,PREGRP4 appropriately
with EMC/MXC.
2006-07-29 Richard Sandiford <richard@codesourcery.com>
* m68k-opc.c (m68k_opcodes): Fix operand specificer in the Coldfire
