目的
DXBC 肯定没有可读性 HLSL 而且我们在 Unity 中平常写的 Shader 多以 HLSL 的语法为主
因为之前有尝试 DXBC 还原恢复到 HLSL
在此过程中，发现了大量的机械化工作：每一个 ASM API 都要转化为对应的 HLSL 代码
然后结合上下文的指令逻辑猜测 HLSL 的逻辑代码
我们将写工具 DXBC2HLSL 最大的目的是减少上述内容：大量的机械化活动
工作制作思路
- 将 dcl_xxx 特殊处理：定义信息的正则提取
- 将 指令部分 使用简单的语义检查(逐字符 扫描 可以)，提取指令名，使用参数(寄存器，什么类型的寄存器，或常量，等)。
- 最终提取的定义信息和指令信息 转换输出对应 HLSL 代码

扩展
(后续有空回来再整)
- 指令中所有的参数部分使用到分量根据指令，或是结果寄存器使用的分量来适合
- 提取、输出DXBC的注释
- 可以输出每一个转换后的HLSL对应的DXBC（放在 HLSL 代码上一句），便于检测转换无误
- 自动检测出
mul(pos, matrix)或是mul(matrix, pos)的语句转换 - 自动检测出
normalize的语句转换
整个工具写下来，貌似没有发现如何能将 shader 中的 meta 数据提取 RenderDoc, GPA 中有些游戏的 shader 可以提取到，有些不行
不过能提取到的，都可以直接再 RenderDoc 或是 GPA 中提取到 HLSL 也就不需要我写的这个工具处理了
所以我这个工具最终还是为了只提供了 DXBC，然后一键转换 HLSL，减少一部分的代码机械化的转换
