--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
It looks like both the pragma and the attribute accept any kind of -f/-O
options
regardless of them being marked as 'Optimization' in the .opt file. They
get applied via decode_options and thus may have side-effects not reflected by
cl_optimization_save/restore.
I have a patch to issue
/tmp/t.c:2:9: warning: bad option -fno-lto to pragma attribute [-Wpragmas]
#pragma GCC optimize ("-fno-lto")
