Perhaps it is time to introduce some additional requirements for
candidate patches.
Anything that breaks bootstrap prevents other developers making progress.
I would have thought that bootstrap-O3 would be a minimal requirement
for any patch.
The protocol is published at:
https://gcc.gnu.org/contribute.html#testing
In practice I use this:
CC="clang -Wall" CXX="clang++ -Wall" \
../trunk.git/configure --prefix=/home/dcb/gcc/$PREFIX \
--disable-multilib \
--disable-werror \
--with-pkgversion=$HASH \
--enable-checking=df,extra,fold,rtl,yes \
--enable-languages=c,c++,fortran
sed 's/-O2/-O3 -march=native/' < Makefile > Makefile.tmp
diff Makefile Makefile.tmp
mv Makefile.tmp Makefile
This works well for me.
