Thank you Wei. It's interesting though that the full vs HVM only is almost identical in terms of SLOC's Lars
The cloc target counts the files in the dependency graph generated by make.
Do we know for sure that CLOC counts everything in a file or does it honour the pre-processor settings?
We certainly don't feed any preprocessor defines to it. I doubt it understand C to that level of details anyway.
LoC isn't a fantastic metric under any circumstance.
Bigger code is definitely better, if the reason it is bigger is because it is because it is formatted for readability/clarity etc.
Attempting to optimise for smaller LoC, other than making entire functional areas optional, is usually short sighted.
For instance, we could probably decrease the LoC by nearly 20k by changing the style not to give the opening bracket its own line:
$ find . -name '*.c' | xargs grep '^[[:space:]]*{' | wc -l 19896 $ find . -name '*.[ch]' | xargs grep '^[[:space:]]*{' | wc -l 21847
This is hypervisor only BTW (run from xen.git/xen).It is a bit mind-boggling to think that there are more open brackets inthe Xen code base than there is PV-specific code. O_o
As we have the same coding conventions across hypervisor code, that shouldn't make a difference
