Can you send me the data declaration for abc ?

I’ve tried a few different combinations of this and it appears to work for me.

Hi,

Thanks for looking into these issues.

"abc" was really ZMM_BITS30 declared as follows:

ZMM_BITS30 DD
3FFFFFFFh,0,3FFFFFFFh,0,3FFFFFFFh,0,3FFFFFFFh,0,3FFFFFFFh,0,3FFFFFFFh,0,3FFFFFFFh,0,3FFFFFFFh,0

Best regards,
George Woltman

Hi,

We have implemented some changes for this which will be ready either later today or tomorrow.

There are some notes however:

Technically, there is no instruction vmovdqa zmm(n), …

Rather only vmovdqa32 or vmovdqa64.

As such we’ve added automatic conversion of the instruction, so vmovdqa zmm(n),MEM with automatically convert to vmovdqa32/64.

The ensure proper types however we are forcing the requirement for ZMMWORD type reference.. that means that:

   vmovdqa zmm1, ZMMWORD PTR ZMM_BITS30  ;this will work

   ;vmovdqa zmm1, YMMWORD PTR ZMM_BITS30 ;this will fail (Cannot move YMMWORD type to ZMM(n)

   vmovdqa ymm1, YMMWORD PTR YMM_BITS30  ;this will work

   ;vmovdqa zmm1, ZMM_BITS30             ;this will fail  (no ZMMWORD type, source data is DD type)

   ;vmovdqa ymm1, YMM_BITS30             ;this will work

Regards,

John

Please download the latest package from the site and re-test. This latest build of 2.15 r2 should solve the AVX2, ZMM encoding issues you have had (plus a few more we found!).

Regards,

John
