Mistake in AMD GCN 3 ISA Reference (VOP_SDWA, VOP_DPP)

Hi, I am amateur.

I found mistake in AMD GCN3 ISA Reference in VOP2, VOP1 and VOPC encoding format. In these places manual describes values in SRC0 field and

describes 249 and 250 values as reserved. This is mistake because these values indicates respectively VOP_SDWA and VOP_DPP additional dwords whose were described in VOP_SDWA and VOP_DPP sections.

Dear AMD engineers. Can you fix GCN3 ISA Refman and provide correct reference?

I just want to thank You for mentioning this new manual.

I've checked the new things in it. There are very cool improvements for byte based things. Good job, AMD!
