a4c6bd0821 S/390: libatomic: Fix 16 byte atomic exchange
The compiler builtin will use the hardware instruction cdsg if the
memory operand is properly aligned and will fall back to the
library call otherwise.
In case the compiler for one part is able to detect that the
location is aligned and fails to do so for another usage of the hw
instruction and the sw fall back would be mixed on the same memory
location.  To avoid this the library fall back also has to use the
hardware instruction if possible.

14e335edc8 CET shouldn't be enabled in 32-bit run-time libraries by defualt
ENDBR32 and RDSSPD are multi-byte NOPs on x86-64 processors and
newer x86 processors, starting Pentium Pro.  They are UD on older
32-bit processors. Detect this at configure time and adjust the
default value for enable_cet. GCC will enable CET in 32-bit run-time
libraries in any case if --enable-cet is used to configure GCC.

e64944ac65 [arm] Fix architecture selection when building libatomic with automatic FPU selection
Libatomic builds a few functions for Arm with an explicit -march
option.  This option does not specify an FPU, which can lead to
problems when targeting a hard-float or softfp environment since the
architecture appears to be incompatible with the selected ABI.

The fix is simple enough, just add +fp (the minimum floating point
option) to the architecture.  We don't use anything from the FP
architecture, so it shouldn't really change anything; and if we are
building for -mfloat-abi=soft the canonicalization process will remove
the unnecessary fp attributes anyway.

	* Makefile.am: (IFUNC_OPTIONS): Set the architecture to
	-march=armv7-a+fp on Linux/Arm.
	* Makefile.in: Regenerated.

7c961392a6 Fix libatomic multilib parallel build (PR other/67627)
The all-multi target may be built in parallel with the %_.lo
targets which generate make dependencies that are parsed during
the build of all-multi.

This patch forces all-multi to only run after the *_.lo targets
are done.

libatomic:
	PR other/67627
	* Makefile.am (all-multi): Add dependency.
	* Makefile.in: Regenerate.

c29c36ad5d Add out-of-line versions of some <stdatomic.h> functions (PR c/65083).
PR c/65083 notes that some functions in <stdatomic.h> are normal
functions, not generic functions, and so need to have out-of-line
copies that can be called when macro expansion is suppressed (unlike
the generic functions where DR#419 makes it undefined if you suppress
a macro expansion).

This patch adds such out-of-line definitions in libatomic for those
six functions, at a new LIBATOMIC_1.2 symbol version, as trivial
wrappers to the <stdatomic.h> macros, along with declarations of those
functions in <stdatomic.h>.  Tests are added that are based on the
corresponding tests for the macros, but with parentheses around the
function names to force the out-of-line functions to be used.

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

gcc:
	* ginclude/stdatomic.h (atomic_thread_fence, atomic_signal_fence)
	(atomic_flag_test_and_set, atomic_flag_test_and_set_explicit)
	(atomic_flag_clear, atomic_flag_clear_explicit): Declare as
	functions before defining as macros.

gcc/testsuite:
	* gcc.dg/atomic/stdatomic-fence-2.c,
	gcc.dg/atomic/stdatomic-flag-2.c: New tests.

libatomic:
	* fence.c, flag.c: New files.
	* Makefile.am (libatomic_la_SOURCES): Add fence.c and flag.c.
	* Makefile.in: Regenerate.
	* configure.ac (libtool_VERSION): Change to 3:0:2.
	* configure: Regenerate.
	* libatomic.map (LIBATOMIC_1.2): New symbol version.

9e531d3749 Testsuite: add dg-{begin|end}-multiline-output commands
This patch adds an easy way to write tests for expected multiline
output.  For example we can test carets and underlines for
a particular diagnostic with:

/* { dg-begin-multiline-output "" }
 typedef struct _GMutex GMutex;
                ^~~~~~~
   { dg-end-multiline-output "" } */

multiline.exp is used by prune.exp; hence we need to load it before
prune.exp via *load_gcc_lib* for the testsuites of the various
non-"gcc" support libraries (e.g. boehm-gc).

gcc/testsuite/ChangeLog:
	* lib/multiline.exp: New file.
	* lib/prune.exp: Load multiline.exp.
	(prune_gcc_output): Call into multiline.exp to handle any
	multiline output directives.
	* lib/libgo.exp: Load multiline.exp before prune.exp, using
	load_gcc_lib.
