研究方向
The issue reports that update llc test checks.py fails on Windows due to differences in assembly output. First, review the 13 comments in the issue for any suggested fixes or analysis. Then, examine the script (likely in utils/update llc test checks.py) to understand how it parses assembly. Compare the assembly output on Windows and Linux to identify the specific differences that cause the failure. Consider checking if there are existing test cases that reproduce the issue.
