How about this then?
Jan
The VGATHER group of instructions requires that all three involved
xmm/ymm registers are distinct. This patch adds code to check for this,
and at once eliminates a superfluous check for not using PC-relative
addressing for these instructions (the fact that an index register is
required here already excludes valid PC-relative addresses). The
severity of the resulting diagnostics can be controlled via command
line option or directive.
Note that this patch depends on the introduction of register_number(),
which is being done by the patch at
http://www.sourceware.org/ml/binutils/2012-08/msg00119.html.

2012-08-07 Jan Beulich <jbeulich@suse.com>
* config/tc-i386.c (set_check): Renamed from set_sse_check.
Generalize to also handle operand checking option.
(enum i386_error): New enumerator 'invalid_vector_register_set'.
(match_template): Handle it.
(enum check_kind): Give it a tag. Drop sse_ prefixes from
enumerators.
(operand_check): New.
(md_pseudo_table): Add "operand_check".
(check_VecOperands): Don't special case RIP addressing. Check
that vSIB operands use distinct vector registers unless no
checking was requested.
(OPTION_MOPERAND_CHECK): New.
(md_parse_option): Handle it.
(OPTION_MAVXSCALAR, OPTION_X32): Adjust.
(md_longopts): Add "moperand-check".
(md_show_usage): Add help text for it.
