-------------------------+--------------------------------------------------
I took sage-5.0.beta9, replaced the ppl package by the one from #12672,
added the cloog-ppl package from #12666, replaced the glpk package by the
one from #12703, added a new libelf spkg, added the mpc and gcc spkgs from
#12369 and modified the gcc spkg such that the gcc is built with support
of loop optimization (graphite) and lto.
Then, I tried to build Sage with rather high optimization:
{{{
king@mpc622:/mnt/local/king/SAGE/testinggcc/lto/sage-5.0.beta9$ echo
$CFLAGS
-O3 -march=native -floop-interchange -floop-strip-mine -floop-block -fno-
strict-aliasing -flto
king@mpc622:/mnt/local/king/SAGE/testinggcc/lto/sage-5.0.beta9$ echo
$CXXFLAGS
-O3 -march=native -floop-interchange -floop-strip-mine -floop-block -fno-
strict-aliasing -flto
king@mpc622:/mnt/local/king/SAGE/testinggcc/lto/sage-5.0.beta9$ echo
$LDFLAGS
-flto
}}}
It was needed to temporarily remove `-flto` in order to build Singular
(see #12738). Later, R failed to build - see this
