Series [committed,01/19] configure, d: Add support for bootstrapping the D front-end |

Commit Message

Iain Buclaw Nov. 30, 2021, 2:14 p.m. UTC 
  The D front-end is now itself written in the D language.  In order to
build GDC you will need a working GDC compiler (GCC version 9.1 or later).
Predominantly I have been testing with 10.3 on x86_64-linux, 11.2 on
mips-linux, ppc64le-linux, and sparc-solaris, and current mainline on
x86_64-darwin20.

This series is split up to keep the size down, but has been committed as
one changeset.  All other changes that follow deal with removing the old
and importing the new D front-end sources.

This patch adds the required components in order to have a D front-end
written in D itself.  Because the compiler front-end only depends on the
core runtime modules, only libdruntime is built for the bootstrap stages.

Reviewed: https://gcc.gnu.org/pipermail/gcc-patches/2021-October/582828.html

Bootstrapped and regression tested on x86_64-linux-gnu, and committed to
mainline.

Regards,
Iain.
