Comment (by SimonKing):
Here is another experience:
I patched the gcc spkg as follows:
{{{
#!diff
diff --git a/spkg-install b/spkg-install
Index: spkg-install
===================================================================
--- a/spkg-install
+++ b/spkg-install
@@ -82,6 +82,8 @@
../src/configure \
--prefix="$SAGE_LOCAL" \
--with-local-prefix="$SAGE_LOCAL" \
+ --with-cloog="$SAGE_LOCAL" --with-ppl="$SAGE_LOCAL" \
+ --enable-lto \
--with-gmp="$SAGE_LOCAL" --with-mpfr="$SAGE_LOCAL" --with-
mpc="$SAGE_LOCAL" \
--with-system-zlib \
--disable-multilib \
}}}
Then, I added the modified gcc spkg to 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
and of course also added the mpc spkg. I didn't bother to modify the
spkg/deps file, but instead built the gcc spkg manually after installing
the dependencies for graphite and lto support.
I have tried to build Sage with `C(XX)FLAGS="-O3 -march=native -floop-
interchange -floop-strip-mine -floop-block -fno-strict-aliasing -flto"`
and LDFLAGS=-flto. Singular did not build (see #12738) and R did not build
(see #12741), so that I removed `-flto` for these two spkgs.
In principle, it worked. sage -testall resulted in
{{{
All tests passed!
Total time for all tests: 6515.9 seconds
}}}
However, that is significantly ''slower'' than the 4951.8 seconds that
sage -testall would take on this machine without optimization flags and
with gcc 4.6.2.
Note that Leif pointed out that the failures when building Singular and R
might come from a slightly too old ld version on my system. But don't be
afraid: I do ''not'' intend to create a binutils spkg.
