Subject: [PATCH] x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if needed
When -z separate-code, which is enabled by default for Linux/x86, is
used to create executable, ld won't place any data in the code-only
PT_LOAD segment. If there are no data sections placed before the
code-only PT_LOAD segment, the program headers won't be mapped into
any PT_LOAD segment. When the executable tries to access it (based
on the program header address passed in AT_PHDR), it will lead to
segfault. This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if
there may be no data sections before the text section so that the
first PT_LOAD segment won't be code-only and will contain the program
header.
Testcases are adjusted to either pass "-z noseparate-code" to ld or
discard the .note.gnu.property section. A Linux/x86 run-time test is
added.

Subject: [PATCH] x86: Properly merge GNU_PROPERTY_X86_ISA_1_USED
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
Without the GNU_PROPERTY_X86_ISA_1_USED property, all ISAs may be used.
If a bit in the GNU_PROPERTY_X86_ISA_1_USED property is unset, the
corresponding x86 instruction set isn’t used. When merging properties
from 2 input files and one input file doesn't have the
GNU_PROPERTY_X86_ISA_1_USED property, the output file shouldn't have
it neither. This patch removes the GNU_PROPERTY_X86_ISA_1_USED
property if an input file doesn't have it.
This patch replaces the GNU_PROPERTY_X86_ISA_1_USED property with the
GNU_PROPERTY_X86_ISA_1_NEEDED property which is the minimum ISA
requirement.

Subject: [PATCH 12/12] static-pie
in gcc-8 -static means static non-pie, even if -pie or -static-pie
are specified, -static-pie can be used to build static pie.
in musl toolchains -static -pie always meant static pie, so this
patch fixes the link specs accordingly, the new -static-pie is just
an alias to -static -pie.

Ensure that msgfmt doesn't encounter problems during gcc bootstrapping.
Solves error messages like the following:
msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
The libgcc_s.so used during build doesn't satisfy the needs of the
libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
is used as a stand-alone application here, and what library it uses
behind the scenes is of no concern to the gcc build process.
Therefore, simply invoking it "as usual", i.e. without any special
library path, will make it work as expected here.

Author: Timo Teräs <timo.teras@iki.fi>
Alpine musl package provides libssp_nonshared.a. We link to it unconditionally,
as otherwise we get link failures if some objects are -fstack-protector built
and final link happens with -fno-stack-protector. This seems to be the common
case when bootstrapping gcc, the piepatches do not seem to fully fix the
crosstoolchain and bootstrap sequence wrt. stack-protector flag usage.

From: Jakub Jelinek <jakub@redhat.com>
Subject: [PATCH] Use --push-state --as-needed and --pop-state instead of --as-needed and --no-as-needed for libgcc
As discussed, using --as-needed and --no-as-needed is dangerous, because
it results in --no-as-needed even for libraries after -lgcc_s, even when the
default is --as-needed or --as-needed has been specified earlier on the
command line.
If the linker supports --push-state/--pop-state, we should IMHO use it.
2018-04-11 Jakub Jelinek <jakub@redhat.com>
* configure.ac (LD_AS_NEEDED_OPTION, LD_NO_AS_NEEDED_OPTION): Use
--push-state --as-needed and --pop-state instead of --as-needed and
--no-as-needed if ld supports it.
* configure: Regenerated.

Subject: [PATCH 01/13] i386: Move struct ix86_frame to machine_function
Make ix86_frame available to i386 code generation. This is needed to
backport the patch set of -mindirect-branch= to mitigate variant #2 of
the speculative execution vulnerabilities on x86 processors identified
by CVE-2017-5715, aka Spectre.

Subject: [PATCH 03/13] i386: Use const reference of struct ix86_frame to avoid
copy
We can use const reference of struct ix86_frame to avoid making a local
copy of ix86_frame. ix86_expand_epilogue makes a local copy of struct
ix86_frame and uses the reg_save_offset field as a local variable. This
patch uses a separate local variable for reg_save_offset.
Tested on x86-64 with ada.

Subject: [PATCH 06/13] x86: Add -mindirect-branch-register
Add -mindirect-branch-register to force indirect branch via register.
This is implemented by disabling patterns of indirect branch via memory,
similar to TARGET_X32.
-mindirect-branch= and -mfunction-return= tests are updated with
-mno-indirect-branch-register to avoid false test failures when
-mindirect-branch-register is added to RUNTESTFLAGS for "make check".

x86: Rewrite ix86_indirect_branch_register logic
Rewrite ix86_indirect_branch_register logic with
(and (not (match_test "ix86_indirect_branch_register"))
(original condition before r256662))
Backport from mainline
2018-01-15 H.J. Lu <hongjiu.lu@intel.com>
* config/i386/predicates.md (constant_call_address_operand):
Rewrite ix86_indirect_branch_register logic.
(sibcall_insn_operand): Likewise.
Don't check ix86_indirect_branch_register for GOT operand
Since GOT_memory_operand and GOT32_symbol_operand are simple pattern
matches, don't check ix86_indirect_branch_register here. If needed,
-mindirect-branch= will convert indirect branch via GOT slot to a call
and return thunk.
Backport from mainline
2018-01-15 H.J. Lu <hongjiu.lu@intel.com>
* config/i386/constraints.md (Bs): Update
ix86_indirect_branch_register check. Don't check
ix86_indirect_branch_register with GOT_memory_operand.

Subject: [PATCH 08/13] x86: Disallow -mindirect-branch=/-mfunction-return=
with -mcmodel=large
Since the thunk function may not be reachable in large code model,
-mcmodel=large is incompatible with -mindirect-branch=thunk,
-mindirect-branch=thunk-extern, -mfunction-return=thunk and
-mfunction-return=thunk-extern. Issue an error when they are used with
-mcmodel=large.

Subject: [PATCH 09/13] Use INVALID_REGNUM in indirect thunk processing
Backport from mainline
2018-01-17 Uros Bizjak <ubizjak@gmail.com>
* config/i386/i386.c (indirect_thunk_name): Declare regno
as unsigned int. Compare regno with INVALID_REGNUM.
(output_indirect_thunk): Ditto.
(output_indirect_thunk_function): Ditto.
(ix86_code_end): Declare regno as unsigned int. Use INVALID_REGNUM
in the call to output_indirect_thunk_function.

Subject: [PATCH 11/13] i386: Update -mfunction-return= for return with pop
When -mfunction-return= is used, simple_return_pop_internal should pop
return address into ECX register, adjust stack by bytes to pop from stack
and jump to the return thunk via ECX register.
Revision 257992 removed the bool argument from ix86_output_indirect_jmp.
Update comments to reflect it.
Tested on i686 and x86-64.

Subject: [PATCH 13/13] i386: Don't generate alias for function return thunk
Function return thunks shouldn't be aliased to indirect branch thunks
since indirect branch thunks are placed in COMDAT section and a COMDAT
section with indirect branch may not have function return thunk. This
patch generates function return thunks directly.

Ensure that msgfmt doesn't encounter problems during gcc bootstrapping.
Solves error messages like the following:
msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
The libgcc_s.so used during build doesn't satisfy the needs of the
libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
is used as a stand-alone application here, and what library it uses
behind the scenes is of no concern to the gcc build process.
Therefore, simply invoking it "as usual", i.e. without any special
library path, will make it work as expected here.

From 697a7ba791fce2ffab2ed723d909a89684019e3d Mon Sep 17 00:00:00 2001
From: "Tuan M. Hoang" <tmhoang@flatglobe.org>
Date: Sun, 19 Feb 2017 17:03:33 +0000
Subject: [PATCH] main/gcc : when building gcc-java on s390x, libgcj.so
complains about undefined reference to __data_start. Using
SEARCH_FOR_DATA_START instead solved it. Credit to Andrew Haley at RedHat.

@ -0,0 +1,41 @@
When cross compiling a target gcc, target flags may be used on the host
Configure identifies a number of warning flags (WARN_CFLAGS and
WARN_CXXFLAGS) from the $CC value. The cross compiler may be different
from the host compiler and may not support the same set of flags. This
leads to problems such as:
cc1plus: error: unrecognized command line option "-Wno-narrowing"
cc1plus: error: unrecognized command line option "-Wno-overlength-strings"
Work around this problem by removing the warning flags from the
BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.

Author: Timo Teräs <timo.teras@iki.fi>
Alpine musl package provides libssp_nonshared.a. We link to it unconditionally,
as otherwise we get link failures if some objects are -fstack-protector built
and final link happens with -fno-stack-protector. This seems to be the common
case when bootstrapping gcc, the piepatches do not seem to fully fix the
crosstoolchain and bootstrap sequence wrt. stack-protector flag usage.
