Use FD20 macro that will account for the implicit LSB zero value and is already used for sources. For the new macro we need to use the entire bit-range of the field (55-51), so remove the adjustments we used to do prior to encoding and decoding. Fixes assertion in vkpeak (https://github.com/nihui/vkpeak) when running bf16 tests on BMG. And the code now will correctly apply the subreg_nr to the destination, e.g. a mad(32) gets splitted into two pieces, the generation would not fill out the upper-part of the register ``` mad(16) g13<1>BF g10<8,8,1>BF g12<8,8,1>BF g56<1,1,1>F { align1 1H A@5 }; -mad(16) g13<1>BF g10.16<8,8,1>BF g12.16<8,8,1>BF g57<1,1,1>F { align1 2H A@5 }; +mad(16) g13.16<1>BF g10.16<8,8,1>BF g12.16<8,8,1>BF g57<1,1,1>F { align1 2H A@5 }; ``` Reviewed-by: Matt Turner <mattst88@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/37236>
