Split up optabs.[hc]
optabs.[hc] is a bit of a behemoth. It includes basic functions for querying
what a target can do, related tree- and gimple-level query functions,
related rtl-level query functions, and the functions that actually
generate code. Some gimple optimisations therefore need:
#include "insn-config.h"
#include "expmed.h"
#include "dojump.h"
#include "explow.h"
#include "emit-rtl.h"
#include "varasm.h"
#include "stmt.h"
#include "expr.h"
purely to query whether the target has support for a particular operation.
This patch splits optabs up as follows:
- optabs-query.[hc]: IL-independent functions for querying what a target
can do natively.
- optabs-tree.[hc]: tree and gimple query functions (an extension of
optabs-query.[hc]).
- optabs-libfuncs.[hc]: optabs-specific libfuncs (an extension of
libfuncs.h)
- optabs.h: For now includes optabs-query.h and optabs-libfuncs.h.
Only two files outside optabs need to include both optabs.h and
optabs-tree.h: expr.c and function.c. I think that's expected given
that both are related to expand.
It might be good to split optabs.h further, but this is already quite
a big patch.
I changed can_conditionally_move_p from returning an int to returning
a bool and fixed a few formatting glitches. There should be no other
changes to the functions themselves.

compiler: Issue channel type errors earlier.
When asking for the type of a receive operation, the compiler would
return an error type if the receive operator was being used on an
invalid channel type and the error would be reported in a later pass.
There are several ways that the type checking pass would not see
the original node and fail to issue the error. This patch modifies
receive operations to give an error immediately once it is known that
the channel type is invalid.

[AArch64] Handle literal pools for functions > 1 MiB in size.
This patch fixes the issue in PR63304 where we have
functions that are > 1MiB. The idea is to use adrp / ldr or adrp / add
instructions to address the literal pools under the use of a command line
option. I would like to turn this on by default on trunk but keep this
disabled by default for the release branches in order to get some
serious testing for this feature while it bakes on trunk.
As a follow-up I would like to try and see if estimate_num_insns or
something else can give us a heuristic to turn this on for "large" functions.
After all the number of incidences of this are quite low in real life,
so may be we should look to restrict this use as much as possible on the
grounds that this code generation implies an extra integer register for
addressing for every floating point and vector constant and I don't think
that's great in code that already may have high register pressure.
Tested on aarch64-none-elf with no regressions. A previous
version was bootstrapped and regression tested.
Applied to trunk.

PR28901 -Wunused-variable ignores unused const initialised variables in C
12 years ago it was decided that -Wunused-variable shouldn't warn about
static const variables because some code used const static char rcsid[]
strings which were never used but wanted in the code anyway. But as the
bug points out this hides some real bugs. These days the usage of rcsids
is not very popular anymore. So this patch changes the default to warn
about unused static const variables in C with -Wunused-variable. And it
adds a new option -Wno-unused-const-variable to turn this warning off.
For C++ this new warning is off by default, since const variables can be
used as #defines in C++. New testcases for the new defaults in C and C++
are included testing the new warning and suppressing it with an unused
attribute or using -Wno-unused-const-variable.
