--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
cc1 debug info increases like the following
VM SIZE FILE SIZE
++++++++++++++ GROWING ++++++++++++++
[ = ] 0 .debug_info +1.63Mi +1.3%
[ = ] 0 .debug_str +263Ki +3.4%
[ = ] 0 .debug_abbrev +101Ki +4.9%
[ = ] 0 .debug_line +5.71Ki +0.0%
+44% +16 [Unmapped] +48 +1.2%
-------------- SHRINKING --------------
[ = ] 0 .debug_loc -213 -0.0%
-0.0% -48 .text -48 -0.0%
[ = ] 0 .debug_ranges -16 -0.0%
-0.0% -32 TOTAL +1.99Mi +0.6%
Throwing dzw on both makes the difference

I'm with Jakub here, having the information is useful, esp. at -O0 where
we never had any of it.
