I would like to propose this patch as a step toward building gcc using a
C++ compiler. This patch builds stage1 with the C compiler as usual,
and defaults to building stages 2 and 3 with a C++ compiler built during
stage 1.
I just completed a run using the following language configure options:
../gcc/configure \
...
--enable-build-with-cxx \
--enable-languages=c,c++,fortran,ada \
on x86-64-unknown-linux-gnu. As far as I can see it was successful:
http://gcc.gnu.org/ml/gcc-testresults/2011-07/msg01852.html
For extra fun, the 0:20 UTC run at home using:
../gcc/configure \
...
--with-build-config=bootstrap-lto \
is going to use Ada as a language *of choice* instead of Fortran based
on the value of $RANDOM in the bash shell :-)
language=fortran
if [ $RANDOM -lt 16384 ]
then
language=ada
fi
....
../gcc/configure \
--prefix=/tmp/lto \
--enable-languages=$language \
--with-build-config=bootstrap-lto \
I'll see you tomorrow (evil cackle) :-)
All this is using:
$ gcc -v
Using built-in specs.
