From 36362544fb039599c0eb58d839e90ffb5410ad27 Mon Sep 17 00:00:00 2001
From: Marek Polacek <polacek@redhat.com>
Date: Wed, 9 Feb 2022 15:18:43 -0500
Subject: [PATCH] configure: Implement --enable-host-bind-now
As promised in the --enable-host-pie patch, this patch adds another
configure option, --enable-host-bind-now, which adds -z now when linking
the compiler executables in order to extend hardening. BIND_NOW with RELRO
allows the GOT to be marked RO; this prevents GOT modification attacks.
This option does not affect linking of target libraries; you can use
LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now to enable RELRO/BIND_NOW.
Bootstrapped/regtested on x86_64-pc-linux-gnu (with the option enabled vs
not enabled). I suppose this is GCC 13 material, but maybe I'll get some
comments anyway.
c++tools/ChangeLog:
* configure.ac (--enable-host-bind-now): New check.
* configure: Regenerate.
gcc/ChangeLog:
* configure.ac (--enable-host-bind-now): New check. Add
-Wl,-z,now to LD_PICFLAG if --enable-host-bind-now.
* configure: Regenerate.
* doc/install.texi: Document --enable-host-bind-now.
lto-plugin/ChangeLog:
* configure.ac (--enable-host-bind-now): New check. Link with
-z,now.
* configure: Regenerate.

commit 14c7757e9b751781360737f53b71f851fc356d3d
Author: Jeff Law <jeffreyalaw@gmail.com>

Avoid overly-greedy match in dejagnu regexp.
Occasionally I've been seeing failures with the multi-line diagnostics. It's never been clear what's causing the spurious failures, though I have long suspected a greedy regexp match.
It happened again yesterday with a local change that in no way should affect diagnostics, so I finally went searching and found that sure enough the multi-line diagnostics had a ".*" in their regexp. According to the comments, the .* is primarily to catch any dg directives that may appear -- ie it should eat to EOL, but not multiple lines. But a .* can indeed match a newline and cause it to eat multiple lines.
The fix is simple. [^\r\n]* will eat to EOL, but not further.
Regression tested on x86_64 and on our internal target.

* lib/multiline.exp (_build_multiline_regex): Use a better
regexp than .* to match up to EOL.

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.

[sanitizer] Use _thread_db_sizeof_pthread to obtain struct pthread size
This symbol has been exported (as an internal GLIBC_PRIVATE symbol) from libc.so.6 starting with glibc 2.34. glibc uses it internally for its libthread_db implementation to enable thread debugging on GDB, so it is unlikely to go away for now.
Fixes #52989.

From 088d8e322811394203220663c3b9c925980d57a2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] configure: Implement --enable-host-pie
This patch implements the --enable-host-pie configure option which
makes the compiler executables PIE. This can be used to enhance
protection against ROP attacks, and can be viewed as part of a wider
trend to harden binaries.
It is similar to the option --enable-host-shared, except that --e-h-s
won't add -shared to the linker flags whereas --e-h-p will add -pie.
It is different from --enable-default-pie because that option just
adds an implicit -fPIE/-pie when the compiler is invoked, but the
compiler itself isn't PIE.
Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH
regressions.
I plan to add an option to link with -Wl,-z,now.
c++tools/ChangeLog:
* Makefile.in: Rename PIEFLAG to PICFLAG. Set LD_PICFLAG. Use it.
Use pic/libiberty.a if PICFLAG is set.
* configure.ac (--enable-default-pie): Set PICFLAG instead of PIEFLAG.
(--enable-host-pie): New check.
* configure: Regenerate.
gcc/ChangeLog:
* Makefile.in: Set LD_PICFLAG. Use it. Set enable_host_pie.
Remove NO_PIE_CFLAGS and NO_PIE_FLAG. Pass LD_PICFLAG to
ALL_LINKERFLAGS. Use the "pic" build of libiberty if --enable-host-pie.
* configure.ac (--enable-host-shared): Don't set PICFLAG here.
(--enable-host-pie): New check. Set PICFLAG and LD_PICFLAG after this
check.
* configure: Regenerate.
* doc/install.texi: Document --enable-host-pie.
libcody/ChangeLog:
* Makefile.in: Pass LD_PICFLAG to LDFLAGS.
* configure.ac (--enable-host-shared): Don't set PICFLAG here.
(--enable-host-pie): New check. Set PICFLAG and LD_PICFLAG after this
check.
* configure: Regenerate.
libcpp/ChangeLog:
* configure.ac (--enable-host-shared): Don't set PICFLAG here.

* configure.ac (--enable-host-shared): Don't set PICFLAG here.

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.

This patch backports support for PCH with PIE from upstream trunk.
It squashes two commits:
commit e4641191287ca613529d78a906afe4f029c1c3cd
Author: Iain Sandoe <iain@sandoe.co.uk>
Date: Sat Nov 13 12:26:16 2021 +0000
PCH: Make the save and restore diagnostics more robust.
When saving, if we cannot obtain a suitable memory segment there
is no point in continuing, so exit with an error.
When reading in the PCH, we have a situation that the read-in
data will replace the line tables used by the diagnostics output.
However, the state of the read-oin line tables is indeterminate
at some points where diagnostics might be needed.
To make this more robust, we save the existing line tables at
the start and, once we have read in the pointer to the new one,
put that to one side and restore the original table. This
avoids compiler hangs if the read or memory acquisition code
issues an assert, fatal_error, segv etc.
Once the read is complete, we swap in the new line table that
came from the PCH.
If the read-in PCH is corrupted then we still have a broken
compilation w.r.t any future diagnostics - but there is little
that can be done about that without more careful validation of
the file.

pch: Add support for PCH for relocatable executables [PR71934]
So, if we want to make PCH work for PIEs, I'd say we can:
1) add a new GTY option, say callback, which would act like
skip for non-PCH and for PCH would make us skip it but
remember for address bias translation
2) drop the skip for tree_translation_unit_decl::language
3) change get_unnamed_section to have const char * as
last argument instead of const void *, change
unnamed_section::data also to const char * and update
everything related to that
4) maybe add a host hook whether it is ok to support binaries
changing addresses (the only thing I'm worried is if
some host that uses function descriptors allocates them
dynamically instead of having them somewhere in the
executable)
5) maybe add a gengtype warning if it sees in GTY tracked
structure a function pointer without that new callback
option
Here is 1), 2), 3) implemented.
Note, on stdc++.h.gch/O2g.gch there are just those 10 relocations without
the second patch, with it a few more, but nothing huge. And for non-PIEs
there isn't really any extra work on the load side except freading two scalar
values and fseek.

libcpp: Fix up #__VA_OPT__ handling [PR103415]
stringify_arg uses pfile->u_buff to create the string literal.
Unfortunately, paste_tokens -> _cpp_lex_direct -> lex_number -> _cpp_unaligned_alloc
can in some cases use pfile->u_buff too, which results in losing everything
prepared for the string literal until the token pasting.
The following patch fixes that by not calling paste_token during the
construction of the string literal, but doing that before. All the tokens
we are processing have been pushed into a token buffer using
tokens_buff_add_token so it is fine if we paste some of them in that buffer
(successful pasting creates a new token in that buffer), move following
tokens if any to make it contiguous, pop (throw away) the extra tokens at
the end and then do stringify_arg.
Also, paste_tokens now copies over PREV_WHITE and PREV_FALLTHROUGH flags
from the original lhs token to the replacement token. Copying that way
the PREV_WHITE flag is needed for the #__VA_OPT__ handling and copying
over PREV_FALLTHROUGH fixes the new Wimplicit-fallthrough-38.c test.

c++: Add C++20 #__VA_OPT__ support
The following patch implements C++20 # __VA_OPT__ (...) support.
Testcases cover what I came up with myself and what LLVM has for #__VA_OPT__
in its testsuite and the string literals are identical between the two
compilers on the va-opt-5.c testcase.
2021-08-17 Jakub Jelinek <jakub@redhat.com>
libcpp/
* macro.c (vaopt_state): Add m_stringify member.
(vaopt_state::vaopt_state): Initialize it.
(vaopt_state::update): Overwrite it.
(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
if stringify is true handle __VA_OPT__ stringification.
(create_iso_definition): Handle # __VA_OPT__ similarly to # macro_arg.
