Comment (by SimonKing):
But helas, even the new Singular spkg from 5.0-beta9 (namely
singular-3-1-3-3.p6.spkg) failed to build. I used
{{{
king@mpc622:/mnt/local/king/SAGE/testinggcc/lto/sage-5.0.beta9$ echo
$LDFLAGS
-flto
king@mpc622:/mnt/local/king/SAGE/testinggcc/lto/sage-5.0.beta9$ 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
}}}
Is there a ticket to enable Singular with -flto? Namely, the -floop
options have not been a problem when I recently tried.
