I'd used mode-based element types in the SVE ACLE implementation, but
it turns out that they don't correspond to the <stdint.h> types used by
ILP32 newlib. GCC already knows what the correct <stdint.h> types are,
I just wasn't using the right interface to find them.
A consequence of this is that ILP32 newlib code needs to cast "int *"
pointers to "int32_t *" before passing them to s32 loads and stores,
since int32_t is defined as "long int" rather than "int". That matches
the normal C++ overloading behaviour for this target, where passing
"int *" to:
void f(int32_t *);
void f(int64_t *);
would be ambiguous. It also matches the corresponding <arm_neon.h>
behaviour.

This is a workaround that emits a BTI after the function label if that
is followed by a patch area. We try to remove the BTI that follows the
patch area (this may fail e.g. if the first instruction is a PACIASP).
So before this commit -fpatchable-function-entry=3,1 with bti generates
.section __patchable_function_entries
.8byte .LPFE
.text
.LPFE:
nop
foo:
nop
nop
bti c // or paciasp
...
and after this commit
.section __patchable_function_entries
.8byte .LPFE
.text
.LPFE:
nop
foo:
bti c
nop
nop
// may be paciasp
...
and with -fpatchable-function-entry=1 (M=0) the code now is
foo:
bti c
.section __patchable_function_entries
.8byte .LPFE
.text
.LPFE:
nop
// may be paciasp
...
There is a new bti insn in the middle of the patchable area users need
to be aware of unless M=0 (patch area is after the new bti) or M=N
(patch area is before the label, no new bti). Note: bti is not added to
all functions consistently (it can be turned off per function using a
target attribute or the compiler may detect that the function is never
called indirectly), so if bti is inserted in the middle of a patch area
then user code needs to deal with detecting it.

The problem in the PR was that make_temporary_var_for_ref_to_temp ran before
determine_visibility, so when we copied the linkage of the reference
variable it had not yet been restricted by its anonymous namespace context,
so the temporary wrongly ended up with TREE_PUBLIC set. The natural
solution is to run determine_visibility earlier. But that needs to happen
after maybe_commonize_var increases the linkage of some local variables, and
on targets without weak symbol support, that function does different things
based on the results of check_initializer, which is what calls
make_temporary_var_for_ref_to_temp. To break this circular dependency I'm
calling maybe_commonize_var early, and then again later if the target
doesn't support weak symbols.
It also occurred to me that make_temporary_var_for_ref_to_temp wasn't
handling DECL_VISIBILITY at all, and verified that we were doing the wrong
thing. So I've combined the linkage-copying code from there and two other

ultimately the problem is that when rs6000_emit_cmove is called for floating

compare_mode is also floating point), the expander makes sure the

__has_include is funky in that it is macro-like from the POV of #ifdef and
friends, but lexes its parenthesize argument #include-like. We were
failing the second part of that, because we used a forwarding macro to an
internal name, and hence always lexed the argument in macro-parameter
context. We componded that by not setting the right flag when lexing, so
it didn't even know. Mostly users got lucky.
This reimplements the handline.
1) Remove the forwarding, but declare object-like macros that
expand to themselves. This satisfies the #ifdef requirement
2) Correctly set angled_brackets when lexing the parameter. This tells
the lexer (a) <...> is a header name and (b) "..." is too (not a string).
3) Remove the in__has_include lexer state, just tell find_file that that's
what's happenning, so it doesn't emit an error.
We lose the (undocumented) ability to #undef __has_include. That may well
have been an accident of implementation. There are no tests for it.
We gain __has_include behaviour for all users of the preprocessors -- not
just the C-family ones that defined a forwarding macro.

The initial structure for vendor and personal branches makes use of
the default remote (normally origin) for the upstream
repository). Unfortunately, this causes some confusion, especially for
personal branches because a push will not push to the correct upstream
location. This can be 'fixed' by adding a push refspec for the remote,
but that has the unfortunate consequence of breaking the push.default
behaviour for git push, and it becomes too easy to accidentally commit
something unintended to the main parts of the repository.
To work around this, this patch changes the configuration to use
separate 'remotes' for these additional refs, with one remote for the
personal space and another remote for each vendor's space. The
personal space is called after the user's preferred branch-space
prefix (default 'me'), the vendor spaces are called
vendors/<vendor-name>.
As far as possible, I've made the script automatically restructure any
existing fetch or push lines that earlier versions of the scripts may
have created - the gcc-git-customization.sh script will convert all
vendor refs that it can find, so it is not necessary to re-add any
vendors you've already added.
You might, however, want to run
git remote prune <origin>
after running to clean up any stale upstream-refs that might still be
in your local repo, and then
git fetch vendors/<vendor>
or
git fetch <me>
to re-populate the remotes/ structures.
Also, for any branch you already have that tracks a personal or vendor
branch upstream, you might need to run
git config branch.<name>.remote <new-remote>
so that merges and pushes go to the right place (I haven't attempted
to automate this last part).
For vendors, the new structure means that
git checkout -b <vendor>/<branch> remotes/vendors/<vendor>/<branch>
will correctly set up a remote tracking branch.
Please be aware that if you have multiple personal branches set up, then
git push <me>
will still consider all of them for pushing. If you only want to push
one branch, then either write
git push <me> HEAD
or
git push <me> <me>/branch
as appropriate.
And don't forget '-n' (--dry-run) to see what would be done if this
were not a dry run.
Finally, now that the vendors spaces are isolated from each other and
from the other spaces, I've added an option "--enable-push" to
git-fetch-vendor.sh. If passed, then a "push" spec will be added for
that vendor to enable pushing to the upstream. If you re-run the
script for the same vendor without the option, the push spec will be
removed.

One problem is that speuclative code compares call_stmt and lto_stmt_uid in
a way that may get unwanted effect when these gets out of sync. It does not
make sense to have both non-zero so I added code clearing it and sanity check
that it is kept this way.
Other problem is cgraph_edge::make_direct not working well with multiple
targets. In this case it removed one speuclative target and the indirect call
leaving other targets in the tree.
This is fixed by iterating across all targets and removing all except the good
one (if it exists).

(lto_output_ref): Simplify streaming of stmt.
* lto-streamer-in.c (fixup_call_stmt_edges_1): Clear lto_stmt_uid.
When building offloading cross-compiler from x86_64-linux to nvptx-none, the
build fails with:
../../gcc/cp/coroutines.cc: In function 'tree_node* get_fn_local_identifier(tree, const char*)':
../../gcc/cp/coroutines.cc:2255:12: error: expected ';' before 'char'

* coroutines.cc (get_fn_local_identifier): Fix NO_DOT_IN_LABEL
but non-NO_DOLLAR_IN_LABEL case build.
* config/cris/arit.c (DS): Apply attribute fallthrough.
Without this, there are, for each compilation of arit.c, 30ish
occurrences of "this statement may fall through
[-Wimplicit-fallthrough=]", for lines that look like
case 32: DS; case 31: DS; case 30: DS; case 29: DS;
This marks the parameter &fi as unused so it doesn't
cause a boostrap failure.
committed under the obvious rule.
gcc/ChangeLog:
* config/aarch64/aarch64-sve-builtins-base.cc (memory_vector_mode):
Mark parameter unused.
