2006-11-30 Jan Beulich <jbeulich@novell.com> * i386-dis.c (dis386): Use 'R' and 'O' for cbw/cwd unconditionally. (putop): For 'O' suffix, print 'q' in Intel mode, and mark data prefix used. For 'R' and 'W' suffix, simplify and fix Intel mode. gas/testsuite/ 2006-11-30 Jan Beulich <jbeulich@novell.com> * gas/i386/intel.s: Use Intel syntax in Intel syntax test. * gas/i386/x86-64-cbw.[sd]: New. * gas/i386/x86-64-cbw-intel.d: New. * gas/i386/i386.exp: Run new tests.
