New submission from Serhiy Storchaka:
Here is a patch which gets rid of small performance regression introduced by
issue20426 patch. No need to check flags before cache lookup because patterns
with the DEBUG flag are newer cached.
$ ./python -m timeit -s "import re" -- "re.match('', '')"
Before patch: 9.08 usec per loop
After patch: 8 usec per loop
