The GCC 4.0.0 documentation, page 71 in the PostScript version,
<http://gcc.gnu.org/onlinedocs/gcc-4.0.0/gcc/Optimize-Options.html#Optimize-Options>
in the HTML version, says the following:
-ftree-dce
Perform dead code elimination (DCE) on trees. This flag is enabled by default
at -O and higher.
-ftree-dominator-opts
Perform dead code elimination (DCE) on trees. This flag is enabled by default
at -O and higher.
Dominator options seem to be different from dead code, so presumably these are
different.
Alternatively, if they have the same behavior under different names, that
should be noted explicitly, as
it is elsewhere for such options.
