While continuing to work on a proposal for splitting up the optimization
options section of the GCC manual into subsections (just posted to
gcc@), I found that -funroll-loops and -funroll-all-loops also had
duplicate entries. As with the previous patch to remove the duplicate
for -ftracer, I kept the more featureful of the two entries.
Patch committed as obvious.
