[New-bugs-announce] [issue45363] Use instruction offsets in co_lnotab

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

It was a part of the original patch for issue27129.

As well as in jumping instructions we can use instruction offsets instead of bytes offset in co_lnotab. It increases the range of offsets which can be encoded with a single byte, and therefore reduce the size of co_lnotab and its decoding time. It will allow to simplify the code if we use instruction offsets everywhere.
