README contains a description of the front-end, and brief instructions
for developers.
At the moment the front-end doesn't define any custom tree node, as of
yet. gcc/algol68/a68-tree.def is a placeholder where to have these
node codes.
a68-types.h and a68.h are the main header files used by the front-end.
Together they provide data definitions and prototypes of functions
defined in the .cc files.
ga68.vw contains a revised-report like formal description of the
language implemented by this compiler. This includes GNU extensions.

There were two issues preventing OpenMP reductions of UDTs from working
in modules.
Firstly, we were failing a number of checking asserts in the streaming
logic because the declaration is a DECL_LOCAL_DECL_P but was not
correctly added to the BLOCK of the function template. This is because
cp_parser_omp_declare_reduction only called pushdecl when
!processing_template_decl; correcting this fixed this issue.
The second issue is that modules saw this as a function definition and
so attempted to call allocate_struct_function on it, which crashes.
Given that these reduction functions don't really behave like real
function definitions in any other way, I think the cleanest solution is
to just skip all the function definition post-processing in modules;
this seems to work to get the test functioning correctly, from what I
can see.

The extra handling of jumps across vacuous inits for -std=c++26
or -ftrivial-auto-var-init={zero,pattern} added for P2795R5 is undesirable
when processing_template_decl, because it creates labels without DECL_NAME
and GOTO_EXPRs to those and those can't be tsubsted.
I was afraid the pop_labels and check_goto_1 and check_previous_goto_1
handling might not happen again during instantiation, but clearly it does
happen fully (and has to, because whether some declaration has vacuous
initialization or not can't be decided in some cases when parsing the
template, if dependent types are involved).
So, this patch just restricts the P2795R5 PR114457 r16-4212 changes
to !processing_template_decl and adds 2 copies of the erroneous2.C testcase,
one changing the function into a function template where nothing is
dependent and another one where most of the declarations are dependent.

frv.opt has a few options that have never been documented in the
manual. In the initial commit of the FRV port (prior to the adoption
of .opt files) they were marked as "Internal debug switch" so I have
explicitly made them "Undocumented", consistently with other options
similarly marked in the original port.
The documentation changes all straightforward here, to bring this
section into conformance with conventions being applied through this
chapter of the manual.

The Darwin target options documentation was a bit of a mess, with several
undocumented options, some that were listed in the option summary or mentioned
in discussion of other options but not actually documented, and a large
number of options listed in darwin.opt as being obsolete.
I've undocumented all the obsolete options to streamline things, plus a few
others that seem to have been intentially undocumented or supplanted by
other options. For the others that were probably supposed to documented,
I did my best to guess what they're for by reading the code or just
copying the documentation string in the .opt file, but it's certainly
possible I screwed some up.
