Add & test the remaining arithmetic operations for VecValue in ptodsl by liggest · Pull Request #919 · hw-native-sys/PTOAS

liggest · 2026-07-09T02:23:07Z

ptodsl 中的 VecValue 类型只定义了乘法操作，这个 PR 简单补全了剩余的加、减操作（SIMT 中的向量除法不被 bisheng 支持），使得 ptodsl 在编译带有这些向量运算操作的 kernel 时不会报错，并添加了相应的测试

Code Review

This pull request implements basic vector arithmetic operations (addition, subtraction, and division) for surface values in the DSL, including their reflected counterparts. It also adds a JIT compilation test to verify that these operations lower correctly to MLIR vector instructions. There are no review comments, and I have no feedback to provide.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

你现在在审查 GitHub PR。

仓库：hw-native-sys/PTOAS
PR：#919 Add & test the remaining arithmetic operations for VecValue in ptodsl
作者：liggest
base branch：origin/main
head branch：HEAD（当前已 checkout 到 PR head）

要求：
1. 只审查这个 PR 相对 origin/main 的改动，必要时可以看上下文文件。
2. 重点找真实的 correctness / regression / contract mismatch / CI / runtime / compatibility 问题。
3. 不要提纯风格建议，不要提低价值猜测。
4. 严格按优先级输出：
   - P1：高概率会导致错误结果、编译/运行失败、严重回归、发布阻断
   - P2：重要缺陷、行为回归、遗漏校验/测试、较大兼容性问题
   - P3：次要但明确可改的问题
5. 如果没有问题，summary 直接写：未检查到 PR #919 存在问题，并返回 findings=[]。
6. 如果有问题，summary 简洁概括，findings 里每条都要给出：
   - severity
   - title
   - body（说明为什么是问题，尽量具体）
   - file（尽量给相对路径）
   - line（能确定就填整数，否则 null）

建议先查看：
- git status --short
- git diff --stat origin/main...HEAD
- git diff --unified=80 origin/main...HEAD

最终输出必须严格匹配 JSON schema。
