From 8bcc0f85ed1718c0dd9033ad4a34df181aabaffe Mon Sep 17 00:00:00 2001
From: Mark Eggleston <markeggleston@gcc.gnu.org>
Date: Fri, 22 Jan 2021 13:11:06 +0000
Subject: [PATCH 05/10] Allow old-style initializers in derived types
This allows simple declarations in derived types and structures, such as:
LOGICAL*1 NIL /0/
Only single value expressions are allowed at the moment.
Use -fdec-old-init to enable. Also enabled by -fdec.

From 786869fd62813e80da9b6545a295d53c36275c19 Mon Sep 17 00:00:00 2001
From: Mark Eggleston <markeggleston@gcc.gnu.org>
Date: Fri, 22 Jan 2021 13:12:14 +0000
Subject: [PATCH 06/10] Allow string length and kind to be specified on a per
variable basis.
This allows kind/length to be mixed with array specification in
declarations.
e.g.
INTEGER*4 x*2, y*8
CHARACTER names*20(10)
REAL v(100)*8, vv*4(50)
The per-variable size overrides the kind or length specified for the type.
Use -fdec-override-kind to enable. Also enabled by -fdec.
Note: this feature is a merger of two previously separate features.
Now accepts named constants as kind parameters:
INTEGER A
PARAMETER (A=2)
INTEGER B*(A)
Contributed by Mark Eggleston <mark.eggleston@codethink.com>
Now rejects invalid kind parameters and prints error messages:
INTEGER X*3
caused an internal compiler error.

Subject: [PATCH 02/10] Convert LOGICAL to INTEGER for arithmetic ops, and vice
versa
We allow converting LOGICAL types to INTEGER when doing arithmetic
operations, and converting INTEGER types to LOGICAL for use in
boolean operations.
This feature is enabled with the -flogical-as-integer flag.
Note: using this feature will disable bitwise logical operations enabled by
-fdec.

libgcc: Honor LDFLAGS_FOR_TARGET when linking libgcc_s
When building gcc with some specific LDFLAGS_FOR_TARGET, e.g.
LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now
those flags propagate info linking of target shared libraries,
e.g. lib{ubsan,tsan,stdc++,quadmath,objc,lsan,itm,gphobos,gdruntime,gomp,go,gfortran,atomic,asan}.so.*
but there is one important exception, libgcc_s.so.* linking ignores it.
The following patch fixes that.
Bootstrapped/regtested on x86_64-linux with LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now
and verified that libgcc_s.so.* is BIND_NOW when it previously wasn't, and
without any LDFLAGS_FOR_TARGET on x86_64-linux and i686-linux.
There on x86_64-linux I've verified that the libgcc_s.so.1 linking command
line for -m64 is identical except for whitespace to one without the patch,
and for -m32 multilib $(LDFLAGS) actually do supply there an extra -m32
that also repeats later in the @multilib_flags@, which should be harmless.

c++: Optimize constinit thread_local vars [PR101786]
The paper that introduced constinit mentioned in rationale that constinit
can be used on externs as well and that it can be used to avoid the
thread_local initialization wrappers, because the standard requires that
if constinit is present on any declaration, it is also present on the
initialization declaration, even if it is in some other TU etc.
There is a small problem though, we use the tls wrappers not just if
the thread_local variable needs dynamic initialization, but also when
it has static initialization, but non-trivial destructor, as the
"dynamic initialization" in that case needs to register the destructor.
So, the following patch optimizes constinit thread_local vars only
if we can prove they will not have non-trivial destructors. That includes
the case where we have incomplete type where we don't know and need to
conservatively assume the type will have non-trivial destructor at the
initializing declaration side.

compilers on the va-opt-5.c testcase.

(vaopt_state::stringify): New method.
(stringify_arg): Replace arg argument with first, count arguments
and add va_opt argument. Use first instead of arg->first and
count instead of arg->count, for va_opt add paste_tokens handling.
(paste_tokens): Fix up len calculation. Don't spell rhs twice,
instead use %.*s to supply lhs and rhs spelling lengths. Don't call
_cpp_backup_tokens here.
(paste_all_tokens): Call it here instead.
(replace_args): Adjust stringify_arg caller. For vaopt_state::END
