Most of the standard prelude is implemented in a combination of code
lowered by the front-end (standard operators, contants, etc) and
functions provided by the libga68 run-time library, to which the
former libcalls. Until now, all the support routines in libga68 were
written in C. However, many of the transput facilities are better
implemented in Algol 68.
The Revised Report includes a reference implementation (code listing)
of many of the standard routines. This implementation, however, makes
use of an "extended" program notation in order to denote certain
notions to avoid repetitive code. Therefore this commit includes
sppp, a build-time pre-processor written in awk that is only intended
to be used internally by the libga68 run-time library. This
preprocessor allows us to write code like:
proc subwhole = (Number v, int width) string:
case v in
{iter L {short short} {short} {} {long} {long long}}
{iter S {LENG LENG} {LENG} {} {SHORTEN} {SHORTEN SHORTEN}}
({L} int x):
begin string s, {L} int n := x;
while dig_char ({S} (n MOD {L} 10)) +=: s;
n %:= {L} 10; n /= {L} 0
do ~ od;
(UPB s > width | width * errorchar | s)
end
{reti {,}}
esac;
Resulting in cases for short short int, short int, int, long int and
long long int being macro-expanded in the routine's conformance
clause.
This commit also adds the necessary infrastructure for writing Algol
68 code in the libga68 library, including the ability of having
modules exported by libga68. An implementation of some of the
transput routines is also provided in standard.a68: whole, fixed,
float, string_to_L_real, char_in_string, L_int_width, L_real_width and
L_exp_with.
The build system changes include the backport of the Automake Algol 68
support, which is in a released version of Automake but not in the
version used for GCC, to libga68/m4/autoconf.m4.

In the explict-relocs path through the RISC-V backend we generate sequences
using auipc which stores its result in a GPR.
Under the right circumstances we can end up with cases where we try to use
pseudos which may not be Pmode sized or worse yet may be a floating point mode.
This patch forces those paths to generate a fresh temporary when the provided
one isn't already Pmode. That helps this bug, but I'm not 100% convinced the
explict-relocs stuff is correct and I wouldn't be surprised to find other bugs
lurking in here.

This fixes up a missed optimization regression for riscv in ifcvt after r16-6350-g9e61a171244110.

After failing to parse a type-requirement during tentative parsing and
hitting error recovery code in cp_parser_skip_to_end_of_statement that

[basic.link] p14.4 says that a declaration naming a TU-local entity is
an exposure, ignoring "any reference to a non-volatile const object or
reference with internal or no linkage initialized with a constant
expression that is not an odr-use".
To implement this, we cannot stream these entities but must fold them
into their underlying values beforehand. This was already done to a
degree by cp_fold, but it didn't handle all cases, and notably was not
performed on the saved body of a constexpr function, which would then
cause errors during modules streaming.
This patch implements this by supplementing cp_fold with additional
rules to fold non-ODR usages of contants. We need to do this as an
additional walk before saving the constexpr function definition, so we
also disable as much other folding during this walk as possible to
prevent removing any information that the constexpr interpreter
requires to function correctly.
With this we still will error on uses in templates. In general it's
impossible to tell within an uninstantiated template body whether a
reference is an ODR-use in the face of dependent expressions, so we
don't attempt to do anything for this case.

GNU ld gained separate Solaris-specific linker emulations (*_sol2) long
ago. Since their introduction, GCC has preferred them over their
non-*_sol2 counterparts but supported both forms. This has changed for
GCC 16: since all supported versions of GNU ld do support the *_sol2
emulations, GCC now uses them unconditionally.
libtool has also been updated to handle this since libtool 2.4.2 back in
2011. However, that change has only partially been backported to the
heavily patched libtool.m4 in the GCC tree: the sparcv9 part is there,
but the amd64 part is missing for some reason. This causes problems
with some recent binutils changes.
Therefore this patch cherry-picks the libtool patch to bring
Solaris/x86_64 in sync with Solaris/sparcv9 and upstream libtool.
Bootstrapped without regressions on {amd64,i386}-pc-solaris2.11 and

dwarf2out uses "LM" for line-info labels in text sections, using the
global counter line_info_label_num to get unique label names. The
Algol 68 exports were using the same string for the mode labels in the
.a68_exports sections using its own private counter. This led to
assemblers to not be happy whey they find duplicated labels in the

So the problem here is during LRA we are eliminating argp and trying to
simplify the RTL as we go but inside a debug insn, almost all subreg
are valid due to gen_lowpart_for_debug done during debug insn simplification.
So simplify_gen_subreg will fail on some subregs and return null.
This causes problems later on. The solution is create a raw SUBREG

9. It is the precursor to current GNU CTF, meant primarily for tools
like the low-level debugger mdb or DTrace that would like to avoid the
overhead of full DWARF-2 debugging information. However, for a long
time creation required separate steps to convert DWARF information
(version 2 only) to CTF in the input objects and later merge this into
the final objects. The tools to do so were available, but they were
barely documented and their use restricted to the core OS because of
this difficulty.
There's recently been a massive effort to simplify this and allow for
wider adoption. The native linker has been extended to take GNU CTF
info in the input objects and convert that to Solaris CTF itself. At
the same time, the massively enhanced tools and the format itself are
fully documented.
To make this even simpler to use, this patch introduces a new -gsctf
option to hide the details from users. At compile time, it just passes
-gctf to the compiler, and at link time it invokes ld with -z ctf.
Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11.

Several recent tests that use check-function-bodies on x86 FAIL on Solaris:
they all lack dg-add-options check_function_bodies which is required to
handle some Solaris differences. One test also needs -fomit-frame-pointer
to deal with a different Solaris/x86 default.
Tested on i386-pc-solaris2.11 and x86_64-pc-linux-gnu.

With Solaris/x86 as, GCC uses the -xbrace_comment option if supported.
Since it is present in the Solaris 11.4 FCS assembler and 11.4 is the
only supported Solaris version, this check is no longer necessary.

As planned, this commit removes a crude hack (the coalescing of 'pub'
symbols right after bottom-up parsing) that I introduced during the
initial implementation of modules. The goal was to get working
separated compilation as soon as possible. Now the rest of the
parser, and also the lowerer pass, is made to know about these 'pub'
symbols.
