--- Comment #25 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I have, and it doesn't make much difference:
175800 gcc48.so
608280 gcc49.so
1159624 gcc5-cow.so
1176296 gcc6-cow-gc.so
1176296 gcc6-cow.so
1180400 gcc6-gc.so
1180400 gcc6.so
258376 gcc7-cow-patched.so
1188568 gcc7-cow-trunk.so
258384 gcc7-patched.so
1188552 gcc7-trunk.so
-cow means using -D_GLIBCXX_CXX11_ABI=0
-gc means using -Wl,--gc-sections
-patched means I've split the explicit instantiations into separate files and
changed __snprintf_lite to not use __int_to_char from locale-inst.o
The patch makes a big difference.
