A lot of people at Mozilla didn't know that the GNU toolchain
supported C preprocessor macro debugging information; they've started
using it now. Because DWARF doesn't allow different CUs' macro
information to share strings, .debug_macinfo ends up being 12x the
size of .text. I told them, "It's a bit bulky; you might want to
check your build tree sizes." Nobody cares. They love it.
Different organizations have different concerns. I think it's a
mistake for GCC to assume that a GiB is precious; it's not so for many
