[PATCH 0/2] MR122: vkd3d-shader/sm4: Set "dst_count" to 0 when we clear "dst" in shader_sm4_read_instruction().

[PATCH 1/2] vkd3d-shader/sm4: Set "dst_count" to 0 when we clear "dst" in shader_sm4_read_instruction().

[Henri Verbeet]

From: Henri Verbeet

VKD3D_SM4_OP_DCL_RESOURCE currently has 1 for "dst_count", but NULL for
"dst". This is largely harmless because we never attempt to access the
destintation register of VKD3DSIH_DCL instructions, but nevertheless not
quite proper.

[PATCH 2/2] vkd3d-shader/sm4: Do not specify a destination register for VKD3D_SM4_OP_DCL_RESOURCE in opcode_table[].

[Henri Verbeet]

From: Henri Verbeet

We do not set one in shader_sm4_read_dcl_resource(), and
shader_sm4_read_instruction() explicitly sets this to 0.
