vplan log
Hi all! My first issue here.
Python script in LLVM project called
extract_vplan.py:(https://github.com/llvm/llvm-project/blob/master/llvm/utils/extract_vplan.py#L27
is not able to extract VPlan graph because of regexp matching error. It seems
logging output has changed and regexp in the python script is not updated.
Following error is produced:
File "../llvm/llvm/utils/extract_vplan.py", line 30, in <module>
raise ValueError("Can't get the right VPlan name")
ValueError: Can't get the right VPlan name
I added part of the log file as an attachment which can be used to test this.
To test it run this at llvm project root:
cat digraph.log | python utils/extract_vplan.py --png
When I change the regexp line:
- m = re.search("graph \[.+(VF=.+,UF.+), ", vplan)
+ m = re.search("graph \[.+(VF=.+,UF.+)", vplan)
It starts to work and I'm able to generate png images just fine. I don't think
there are test cases for this. I'd like to contribute and fix this as my first
issue. Any pointers should test be added for this and where?
