The following SyntaxWarning was observed with Python3.12 .
```
llvm-project/clang/tools/libclang/linker-script-to-export-list.py:9:
SyntaxWarning: invalid escape sequence '\s'
m = re.search("^\s+(clang_[^;]+)", line)
```
Similar problem had been reported here
https://stackoverflow.com/questions/57645829/why-am-i-getting-a-syntaxwarning-invalid-escape-sequence-s-warning
.
It would be better to fix it.
Thanks.
