HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; D3D12_SET_WORK_GRAPH_DESC サイズ: 80 バイト(x64)
dim st, 20    ; 4byte整数×20(構造体サイズ 80 / 4 切り上げ)
; ProgramIdentifier : D3D12_PROGRAM_IDENTIFIER (+0, 32byte)  varptr(st)+0 を基点に操作(32byte:入れ子/配列)
; Flags : D3D12_SET_WORK_GRAPH_FLAGS (+32, 4byte)  st.8 = 値  /  値 = st.8   (lpoke/lpeek も可)
; BackingMemory : D3D12_GPU_VIRTUAL_ADDRESS_RANGE (+40, 16byte)  varptr(st)+40 を基点に操作(16byte:入れ子/配列)
; NodeLocalRootArgumentsTable : D3D12_GPU_VIRTUAL_ADDRESS_RANGE_AND_STRIDE (+56, 24byte)  varptr(st)+56 を基点に操作(24byte:入れ子/配列)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
