[PATCH] doc, d: Add note that D front end now requires GDC installed in order to bootstrap.
Hi,
As asked for, this adds the documentation note in install.texi about the
upcoming bootstrap requirements.
Obviously this will be applied alongside the patch posted previously:
https://gcc.gnu.org/pipermail/gcc-patches/2021-October/582917.html
Final batch of testing before proceeding has taking a bit longer than I
expected. Currently bootstrapping on sparcv9-sun-solaris2.11, and will
push forward once have confirmed that it works as well as the current
C++ implementation of the D front end.
OK for mainline? Any improvements on wording?
Thanks,
Iain.
