+       * config/tc-i386.c (md_assemble): Also reject explicit REX
+       prefixes with VEX and alike encoded insns. Zap consumed bits
+       from i.rex.
+       (output_insn): Don't ignore REX prefix for VEX and alike
+       encodings; abort() instead if encountered.
+       * testsuite/gas/i386/x86-64-pseudos.s: Move REX-with-VEX cases
+       ...
+       * testsuite/gas/i386/x86-64-pseudos-bad.s: ... here.

+
+       * config/tc-i386.c (process_operands): Translate explicit REX
+       prefix into i.rex for SSE2AVX templates.
+       (set_rex_vrex): New helper.
+       (build_modrm_byte): Use it.
+       * testsuite/gas/i386/x86-64-sse2avx.s: Add cases with explict
+       REX prefixes.

+       * config/tc-i386.c (cpu_flags_match): Only match SSE2AVX
+       templates when there's no data size prefix.
+       (md_assemble): Reject data size prefix also for legacy encoded
+       SIMD templates.
+       * testsuite/gas/i386/prefix32.s, testsuite/gas/i386/prefix64.s:
+       Uncomment previously not working line.
+       * testsuite/gas/i386/sse2avx.s: Add ldmxcsr/stmxcsr cases with
+       data16 prefix.
