Maybe include some of that data (summary of total binary size change/total debug info size change - and if you could include the flags (was this an -O0 -g build? Optimized (at what level)? Compressed debug info (-gz)? etc) that'd be helpful to better understand the comparison.

Ah, cool - could you include % growth on those rows

(hmm, .debug_line and .debug_str shouldn't be changing in size with this change, right? If you use the same clang version to test the two cases (if you're using a bootstrap with/without the patch applied, then the patch changes itself would show up as changes here))

& if you could include this table in the commit message, that'd be great!

(can you commit this yourself, or do you need someone to do that for you?)
