PR libcc1/113977 points out a case where a simple expression is
rejected with a compiler error message. The bug here is that gdb does
not inform the plugin of the correct alignment -- in fact, there is no
way to do that.
This patch adds a new method to allow the alignment to be set, and
bumps the C front end protocol version.
It also includes some updates to various comments in 'include', done
here to simplify the merge to binutils-gdb.

This fixes version negotiation in the libcc1 plugins. It's done in a
simple way: the version number from the context object is now passed
to base_gdb_plugin.
The idea behind this is that when the client (gdb) requests version N,
the plugin should respond with the newest version that it knows of
that is backward compatible to N. That is, the connection can be
upgraded. Note that the protocol does not change much, and no
backward incompatibilities have ever been needed.
The C plugin is also changed to advertise GCC_C_FE_VERSION_1.
The version negotiation approach should of course be documented, but I
did that in a subsequent patch, in order to only have one patch
touching the 'include' directory and thus needing a merge to
binutils-gdb.

While working on another patch, I discovered that the libcc1 plugin
code never did version negotiation correctly. So, the patches to
introduce v1 never did anything -- the new code, as far as I know, has
never been run.
Making version negotiation work shows that the existing code causes
crashes. For example, safe_lookup_builtin_type might return
error_mark_node in some cases, which the callers aren't prepared to
accept.
Looking into it some more, I couldn't find any justification for this
v1 code for the C compiler plugin. Since it's not run at all, it's
also clear that removing it doesn't cause any regressions in gdb.
However, rather than remove it, this patch changes it to handle
ERROR_MARK better, and then to fall back to the v0 code if the new
code fails to find the type it's looking for.

Here the problem is that we give hard errors while substituting
template parameters during overload resolution of is_throwable
which has an invalid throw in decltype.
The backtrace shows that fn_type_unification -> instantiate_template
-> tsubst* passes complain=0 as expected, but build_throw doesn't
have a complain parameter. So let's add one. Also remove a redundant
local variable which I should have removed in my P2266 patch.
There's still one problem for which I opened <https://gcc.gnu.org/PR113853>.
We need to patch up treat_lvalue_as_rvalue_p and remove the dg-bogus.
Thanks to Patrick for notifying me of this PR. This doesn't fully fix
113789; there I think I'll have to figure our why a candidate wasn't
discarded from the overload set.

Adds the xobj_flag member to lang_decl_fn and a corresponding member access
macro and predicate to support the addition of explicit object member
functions. Additionally, since explicit object member functions are also
non-static member functions, we need to change uses of
DECL_NONSTATIC_MEMBER_FUNCTION_P to clarify whether they intend to include
or exclude them.

Recent Darwin versions place contraints on the use of run paths
specified in environment variables. This breaks some assumptions
in the GCC build.
This change allows the user to configure a Darwin build to use
'@rpath/libraryname.dylib' in library names and then to add an
embedded runpath to executables (and libraries with dependents).
The embedded runpath is added by default unless the user adds
'-nodefaultrpaths' to the link line.
For an installed compiler, it means that any executable built with
that compiler will reference the runtimes installed with the
compiler (equivalent to hard-coding the library path into the name
of the library).
During build-time configurations any "-B" entries will be added to
the runpath thus the newly-built libraries will be found by exes.
Since the install name is set in libtool, that decision needs to be
available here (but might also cause dependent ones in Makefiles,
so we need to export a conditional).
This facility is not available for Darwin 8 or earlier, however the
existing environment variable runpath does work there.
We default this on for systems where the external DYLD_LIBRARY_PATH
does not work and off for Darwin 8 or earlier. For systems that can
use either method, if the value is unset, we use the default (which
is currently DYLD_LIBRARY_PATH).

The GCC_ENABLE_PLUGINS configure logic for detecting whether -rdynamic
is necessary and supported uses an appropriate objdump for $host
binaries (running on $build) in cases where $host is $build or
$target.
However, it is missing such logic in the case where $host is neither
$build nor $target, resulting in the compilers not being linked with
-rdynamic and plugins not being usable with such a compiler. In fact
$ac_cv_prog_OBJDUMP, as used when $build = $host, is always an objdump
for $host binaries that runs on $build; that is, it's appropriate to
use in this case as well.
Tested in such a configuration that it does result in cc1 being linked
with -rdynamic as expected. Also bootstrapped with no regressions for
x86_64-pc-linux-gnu.

My previous nm patch handled all cases but one -- if the user set NM in
the environment to a path which contained an option, libtool's nm
detection tries to run nm against a copy of nm with the options in it:
e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
This is unlikely to be desirable: in this case we should run
"/usr/bin/nm --blargle /usr/bin/nm".
Furthermore, as part of this nm has to detect when the passed-in $NM
contains a path, and in that case avoid doing a path search itself.
This too was thrown off if an option contained something that looked
like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
to see whether that nm exists, finds it doesn't, and wrongly concludes
that nm -p or whatever does not work).
Fix all of these by clipping all options (defined as everything
including and after the first " -") before deciding whether nm
contains a path (but not using the clipped value for anything else),
and then removing all options from the path-modified nm before
looking to see whether that nm existed.
NM=my-nm now does a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM=/usr/bin/my-nm now avoids a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM="my-nm -p../wombat" now does a path search and runs e.g.
/usr/bin/my-nm -p../wombat -B /usr/bin/my-nm
NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm
This seems to be all combinations, including those used by GCC bootstrap
(which, before this commit, fails to bootstrap when configured
--with-build-config=bootstrap-lto, because the lto plugin is now using
--export-symbols-regex, which requires libtool to find a working nm,
while also using -B../prev-gcc to point at the lto plugin associated
with the GCC just built.)

Libtool needs to get BSD-format (or MS-format) output out of the system
nm, so that it can scan generated object files for symbol names for
-export-symbols-regex support. Some nms need specific flags to turn on
BSD-formatted output, so libtool checks for this in its AC_PATH_NM.
Unfortunately the code to do this has a pair of interlocking flaws:
- it runs the test by doing an nm of /dev/null. Some platforms
reasonably refuse to do an nm on a device file, but before now this
has only been worked around by assuming that the error message has a
specific textual form emitted by Tru64 nm, and that getting this
error means this is Tru64 nm and that nm -B would work to produce
BSD-format output, even though the test never actually got anything
but an error message out of nm -B. This is fixable by nm'ing *nm
itself* (since we necessarily have a path to it).
- the test is entirely skipped if NM is set in the environment, on the
grounds that the user has overridden the test: but the user cannot
reasonably be expected to know that libtool wants not only nm but
also flags forcing BSD-format output. Worse yet, one such "user" is
the top-level Cygnus configure script, which neither tests for
nor specifies any BSD-format flags. So platforms needing BSD-format
flags always fail to set them when run in a Cygnus tree, breaking
-export-symbols-regex on such platforms. Libtool also needs to
augment $LD on some platforms, but this is done unconditionally,
augmenting whatever the user specified: the nm check should do the
same.
One wrinkle: if the user has overridden $NM, a path might have been
provided: so we use the user-specified path if there was one, and
otherwise do the path search as usual. (If the nm specified doesn't
work, this might lead to a few extra pointless path searches -- but
the test is going to fail anyway, so that's not a problem.)
(Tested with NM unset, and set to nm, /usr/bin/nm, my-nm where my-nm is a
symlink to /usr/bin/nm on the PATH, and /not-on-the-path/my-nm where
*that* is a symlink to /usr/bin/nm.)
ChangeLog:
* libtool.m4 (LT_PATH_NM): Try BSDization flags with a user-provided
NM, if there is one. Run nm on itself, not on /dev/null, to avoid
errors from nms that refuse to work on non-regular files. Remove
other workarounds for this problem. Strip out blank lines from the
nm output.

This implements ABI-compliant lambda discriminators. Not only do we
have per-scope counters, but we also distinguish by lambda signature.
Only lambdas with the same signature will need non-zero
discriminators. As the discriminator is signature-dependent, we have
to process the lambda function's declaration before we can determine
it. For templated and generic lambdas the signature is that of the
uninstantiated lambda -- not separate for each instantiation.
With this change, gcc and clang now produce the same lambda manglings
for all these testcases.

We currently use a per-extra-scope counter to discriminate multiple
lambdas in a particular such scope. This is not ABI compliant. This
patch merely refactors the existing code to make it easier to drop in
a conformant mangling -- there's no functional change here. I rename
the LAMBDA_EXPR_DISCIMINATOR to LAMBDA_EXPR_SCOPE_ONLY_DISCRIMINATOR,
foreshadowing that there'll be a new discriminator. To provide ABI
warnings we'll need to calculate both, and that requires some
repacking of the lambda_expr's fields. Finally, although we end up
calling the discriminator setter and the scope recorder (nearly)
always consecutively, it's clearer to handle it as two separate
operations. That also allows us to remove the instantiation
special-case for a null extra-scope.

This change adds the configury bits to activate the build of
shared libs on VxWorks ports configured with --enable-shared,
for libraries variants where this is generally supported (rtp,
code model !large - currently not compatible with -fPIC).
Set lt_cv_deplibs_check_method in libtool.m4, so the build of
libraries know how to establish dependencies. This is useful in
configurations such as aarch64 where proper support of LSE relies
on accurate dependency information between libstdc++ and libgcc_s
to begin with.
Regenerate configure scripts to reflect libtool.m4 change.
2022-10-09 Olivier Hainque <hainque@adacore.com>
* libtool.m4 (*vxworks*): When enable_shared, set dynamic_linker
and friends for rtp !large. Assume the linker has the required
abilities and set lt_cv_deplibs_check_method.

In order to properly implement two-stage name lookup for dependent
operator expressions, we need to remember the result of unqualified
lookup of the operator at template definition time, and reuse that
result rather than performing another unqualified lookup at
instantiation time.
Ideally we could just store the lookup in the expression directly, but
as pointed out in r9-6405 this isn't really possible since we use the
standard tree codes to represent most dependent operator expressions.
We could perhaps create a new tree code to represent dependent operator
expressions, with enough operands to store the lookup along with
everything else, but that'd require a lot of careful work to make sure
we handle this new tree code properly across the frontend.
But currently type-dependent operator (and call) expressions are given
an empty TREE_TYPE, which dependent_type_p treats as dependent, so this
field is effectively unused except to signal that the expression is
type-dependent. It'd be convenient if we could store the lookup there
while preserving the dependent-ness of the expression.
To that end, this patch creates a new kind of type, called
DEPENDENT_OPERATOR_TYPE, which we give to dependent operator expressions
and into which we can store the result of operator lookup at template
definition time (DEPENDENT_OPERATOR_TYPE_SAVED_LOOKUPS). Since this
type is always dependent (by definition), and since the frontend doesn't
seem to care much about the exact type of a type-dependent expression,
using this type in place of a NULL_TREE type seems to "just work"; only
dependent_type_p and WILDCARD_TYPE_P need to be adjusted to return true
for this new type.
The rest of the patch mostly consists of adding the necessary plumbing
to pass DEPENDENT_OPERATOR_TYPE_SAVED_LOOKUPS to add_operator_candidates,
adjusting all callers of build_x_* appropriately, and removing the now
unnecessary push_operator_bindings mechanism.
In passing, this patch simplifies finish_constraint_binary_op to avoid
using build_x_binary_op for building a binary constraint-expr; we don't
need to consider operator overloads here, as the &&/|| inside a
constraint effectively always has the built-in meaning (since atomic
constraints must have bool type).
This patch also makes FOLD_EXPR_OP yield a tree_code instead of a raw
INTEGER_CST.
Finally, this patch adds the XFAILed test operator-8.C which is about
broken two-stage name lookup for rewritten non-dependent operator
expressions, an existing bug that's otherwise only documented in
build_new_op.
