gcc/doc/invoke.texi still reads:
@item -fsee
@opindex fsee
Eliminates redundant extension instructions and move the non redundant
ones to optimal placement using LCM.
Enabled at level @option{-O3}.
Would you mind adjusting this as well (and restore it when/if -fsee
gets enabled at -O3 again)?
Thanks,
Gerald
