Christopher Haster	eb8be9f351	Some improvements to size scripts ... - Added -L/--depth argument to show dependencies for scripts/stack.py, this replaces calls.py - Additional internal restructuring to avoid repeated code - Removed incorrect diff percentage when there is no actual size - Consistent percentage rendering in test.py	2022-03-20 03:28:21 -05:00
Christopher Haster	50ad2adc96	Added make *-diff rules, quick commands to compare sizes ... This required a patch to the --diff flag for the scripts to ignore a missing file. This enables the useful one liner for making comparisons with potentially missing previous versions: ./scripts/code.py lfs.o -d lfs.o.code.csv -o lfs.o.code.csv function (0 added, 0 removed) old new diff TOTAL 25476 25476 +0 One downside, these previous files are easy to delete as a part of make clean, which limits their usefulness for comparing configuration changes...	2022-03-11 14:40:54 -06:00
Christopher Haster	d7582efec8	Changed script's CSV formats to allow for merging different measurements ... - size -> code_size - size -> data_size - frame -> stack_frame - limit -> stack_limit - hits -> coverage_hits - count -> coverage_count	2022-03-11 14:40:54 -06:00
Christopher Haster	f4c7af76f8	Added scripts/stack.py for viewing stack usage ... Note this detects loops (recursion), and renders this as infinity. Currently littlefs does have a single recursive function and you can see how this infects the full call graph. Eventually this should be removed.	2022-03-11 14:40:54 -06:00
