../trunk/configure --prefix=/home/dcb/gcc/results \
--disable-bootstrap \
--disable-multilib \
--disable-werror \
--enable-checking=df,extra,fold,rtl,yes \
--enable-languages=c,c++,fortran
I also do some additional top level Makefile tweeking:
sed 's/-O2/-O3 -march=native -Wlogical-op -Wtautological-compare/' \
< Makefile > Makefile.tmp
mv Makefile.tmp Makefile
From /proc/cpuinfo, machine type for -march=native is
model name : AMD FX(tm)-8350 Eight-Core Processor
