0d78e4aa06 re PR fortran/89843 (CFI_section delivers incorrect result descriptor)
2019-04-14  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/89843
	* trans-decl.c (gfc_get_symbol_decl): Assumed shape and assumed
	rank dummies of bind C procs require deferred initialization.
	(convert_CFI_desc): New procedure to convert incoming CFI
	descriptors to gfc types and back again.
	(gfc_trans_deferred_vars): Call it.
	* trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Null the CFI
	descriptor pointer. Free the descriptor in all cases.

	PR fortran/89846
	* expr.c (is_CFI_desc): New function.
	(is_subref_array): Tidy up by referencing the symbol directly.
	* gfortran.h : Prototype for is_CFI_desc.
	* trans_array.c (get_CFI_desc): New function.
	(gfc_get_array_span, gfc_conv_scalarized_array_ref,
	gfc_conv_array_ref): Use it.
	* trans.c (get_array_span): Extract the span from descriptors
	that are indirect references.

	PR fortran/90022
	* trans-decl.c (gfc_get_symbol_decl): Make sure that the se
	expression is a pointer type before converting it to the symbol
	backend_decl type.
	* trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Eliminate
	temporary creation for intent(in).

2019-04-14  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/89843
	* gfortran.dg/ISO_Fortran_binding_4.f90: Modify the value of x
	in ctg. Test the conversion of the descriptor types in the main

	* gfortran.dg/ISO_Fortran_binding_1.c: Correct the indexing for
	the computation of 'ans'. Also, change the expected results for
	CFI_is_contiguous to comply with standard.
	* gfortran.dg/ISO_Fortran_binding_1.f90: Correct the expected

2019-04-14  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/89843
	* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Only
	return immediately if the source pointer is null. Bring
	forward the extraction of the gfc type. Extract the kind so
	that the element size can be correctly computed for sections
	and components of derived type arrays. Remove the free of the
	CFI descriptor since this is now done in trans-expr.c.
	(gfc_desc_to_cfi_desc): Only allocate the CFI descriptor if it
	is not null.
	(CFI_section): Normalise the difference between the upper and
	lower bounds by the stride to correctly calculate the extents
	of the section.

	PR fortran/89846
	* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Use
	the stride measure for the gfc span if it is not a multiple
	of the element length. Otherwise use the element length.

	PR fortran/90022
	* runtime/ISO_Fortran_binding.c (CFI_is_contiguous) : Return
	1 for true and 0 otherwise to comply with the standard. Correct
	the contiguity check for rank 3 and greater by using the stride
	measure of the lower dimension rather than the element length.

0aa6ee3670 Make GFORTRAN_9 symbol node depend on GFORTRAN_8.
At some point when the GFORTRAN_9 node was added it was forgotten to
make it depend on GFORTRAN_8. This patch fixes this.

Committed as obvious.

854cedfd40 Initialize backtrace state once
From backtrace.h for backtrace_create_state:

   Calling this function allocates resources that can not be freed.
   There is no backtrace_free_state function.  The state is used to
   cache information that is expensive to recompute.  Programs are
   expected to call this function at most once and to save the return
   value for all later calls to backtrace functions.

So instead of calling backtrace_create_state every time we wish to
show a backtrace, do it once and store the result in a static
variable.  libbacktrace allows multiple threads to access the state,
so no need to use TLS.

With multiple threads, using an unprotected static variable to check
whether recursion has occured isn't valid, as one thread might have
modified the variable, thus causing another thread to incorrectly

0536d5b37d Replace sync builtins with atomic builtins
The old __sync builtins have been deprecated for a long time now in
favor of the __atomic builtins following the C++11/C11 memory model.
This patch converts libgfortran to use the modern __atomic builtins.

At the same time I weakened the consistency to relaxed for
incrementing and decrementing the counter, and acquire-release when
decrementing to check whether the counter is 0 and the unit can be
freed.  This is similar to e.g. std::shared_ptr in C++.

22e0527251 Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).
This patch updates GCC to use autoconf 2.69 and automake 1.15.1.
(That's not the latest automake version, but it's the one used by
binutils-gdb, with which consistency is desirable, and in any case
seems a useful incremental update that should make a future update to
1.16.1 easier.)

The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf.  Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree.  Autoconf 2.69 has Go support, so
local copies of that support are removed.  I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update.  Changes to how automake generates
runtest calls mean quotes are removed from RUNTEST definitions in five
lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm,
libphobos, libvtv; some others have RUNTEST definitions without
quotes, which are still OK); libgo and libphobos also get
-Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST
do not generate automake warnings.

Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory).  Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.

While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers.  Specifically, most of those warnings
were of the following form (example from libgfortran):

Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled.  For now, the corresponding output
automake: object file(s) will be placed in the top-level directory.  However,
automake: this behaviour will change in future Automake versions: they
will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.

I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed.  In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.

I've tested this with native, cross and Canadian cross builds.  The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.

edaaef601d Use vectored writes when reporting errors and warnings.
When producing error and warning messages, libgfortran writes a
message by using many system calls.  By using vectored writes (the
POSIX writev function) when available and feasible to use without
major surgery, we reduce the chance that output gets intermingled with
other output to stderr.

In practice, this is done by introducing a new function estr_writev in
addition to the existing estr_write.  In order to use this, the old
st_vprintf is removed, replaced by direct calls of vsnprintf, allowing
more message batching.

Regtested on x86_64-pc-linux-gnu.

ef5057c89e [libgfortran] Fix uninitialized variable use in fallback_access
I've been tracking down a bug in a Fortran program on a newlib target and it boils down to fallback_access doing something bad.
The unconditional calls to close cause havoc when open doesn't get called due to the short-circuiting in the if-statement above
because the fd is uninitialised. In my environment GCC ends up calling close on file descriptor 0, thus trying to close stdin.

This patch tightens up the calling so that close is called only when the corresponding open call succeeded.
With this my runtime failure disappears.

Bootstrapped and tested on aarch64-none-linux-gnu.
Though that doesn't exercise this call I hope it's an obviously correct change. 

	* io/unix.c (fallback_access): Avoid calling close on
	uninitialized file descriptor.

72ced87475 Fix interleaving of Fortran STOP messages
Fortran STOP and ERROR STOP use a different function to print the "STOP" string
and the message string.  On GCN this results in out-of-order output, such as
"<msg>ERROR STOP ".

This patch fixes the problem by making estr_write use the proper Fortran write,
not C printf, so both parts are now output the same way.  This also ensures
that both parts are output to STDERR (not that that means anything on GCN).
