x86-64/gas: fix an asymmetry in suffix/register checking
Without this, constructs like "orw %rax, (%rax)" aren't being rejected (other than any other wrong suffix/register combination). gas/ 2013-11-04 Jan Beulich <jbeulich@suse.com> * config/tc-i386.c (check_long_reg): Correct comment indentation. (check_qword_reg): Correct comment and its indentation. (check_word_reg): Extend comment and correct its indentation. Also check for 64-bit register. gas/testsuite/ 2013-11-04 Jan Beulich <jbeulich@suse.com> * gas/i386/x86-64-suffix-bad.[sl]: New. * gas/i386/i386.exp: Run new test.
