Yes. Thank you for the patch you submitted. Your patch was the right
place to change, but I've modified it a little so that AT&T disassembly
isn't changed when an index is used. I think people are used to
seeing the ",1" scale factor on AT&T mode disassembly. Also, note that
patches need ChangeLog entries, and the testsuite needs to be run (and
adjusted in this case).
opcodes/ChangeLog
* i386-dis.c (OP_E): Print scale factor on intel mode sib when not
1. Don't print scale factor on AT&T mode when index missing.
gas/testsuite/ChangeLog
* gas/i386/katmai.d: Adjust for changed sib printing.
* gas/i386/prescott.d: Likewise.
* gas/i386/sse2.d: Likewise.
* gas/i386/ssemmx2.d: Likewise.
ld/testsuite/ChangeLog
* ld-i386/tlsbin.dd: Adjust for changed sib printing.
