* General

- Clean up the sprawl of debian/rules.  I'm sure there are neater
  ways to do some of it; perhaps split it up into some more files?
  Partly done.

- Make debian/rules control build the control file without unpacking
  the sources or applying patches.  Currently, it unpacks the sources,
  patches them, creates the control file, and a subsequent
  dpkg-buildpackage deletes the sources, re-unpacks them, and
  re-patches them.

  This would require hard-coding things like soversions in some
  places. Is it worth it?

- Reorganise debian/rules.defs to decide which packages to build in a
  more straightforward and less error-prone fashion: (1) start with
  all languages; override the list of languages depending on the name
  of the source package (gcc-4.3, gnat-4.3, gdc-4.3).  (2)
  filter the list of languages depending on the target platform; (3)
  depending on the languages to build, decide on which libraries to
  build.

  Now that we build all languages from one source package, should that
  be changed?  Building from separate packages makes building the
  cross compilers more complicated.

- Done: Build both the zero-cost and setjump/longjump exceptions
  versions of libgnat.  In particular, gnat-glade (distributed systems)
  works best with SJLJ.
  This is disabled now in GCC 10.

- Add support for multilib (not yet supported upstream).


* Testsuite

- Only run libgo/x32, if the kernel is prepared to execute the x32
  executables.

- PR target/94278: segfaults running the amdgcn target tools, based
  on LLVM 9 and LLVM 10. https://bugs.llvm.org/show_bug.cgi?id=45887

- Investigate regressions for test failures, seen when turning on the
  hardening flags by default.

- Fix gm2 link errors when running the tests.

- Fix asan test errors in g++. Seen when run locally, e.g. alloca_big_alignment.c
  ==1453818==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.
