Subject: [PATCH] LoongArch: Only allow valid binary op when optimize
conditional move
It is wrong that optimize from `if (cond) dest op= 1 << shift` to
`dest op= (cond ? 1 : 0) << shift` when `dest op 0 != dest`.
Like `and`, `mul` or `div`.
And in this optimization `mul` and `div` is optimized to shift.
gcc/ChangeLog:
* config/loongarch/loongarch.cc
(loongarch_expand_conditional_move): Only allow valid binary
op when optimize conditional move.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/conditional-move-opt-1.c: Remove mul.
* gcc.target/loongarch/conditional-move-opt-2.c: Remove and.
* gcc.target/loongarch/conditional-move-opt-3.c: New test.

Subject: [PATCH] tree-object-size.cc: Fix assert constant offset in
check_for_plus_in_loops [PR122012]
After commit 51b85dfeb19652bf3e0aaec08828ba7cee1e641c, when the
pointer offset is a variable in the loop, the object size of the
pointer may also need to be reexamined.
Which make gcc_assert in the check_for_plus_in_loops failed.

for the variable offset

Subject: [PATCH] gcc: poison-system-directories
Add /sw/include and /opt/include based on the original
zecke-no-host-includes.patch patch. The original patch checked for
/usr/include, /sw/include and /opt/include and then triggered a failure and
aborted.
Instead, we add the two missing items to the current scan. If the user
wants this to be a failure, they can add "-Werror=poison-system-directories".

Subject: [PATCH] specs: turn on -Wl,-z,now by default
Previously, we also used to turn on -z relro here, but we now build
binutils with --enable-relro, which is functionally equivalent.
Binutils does not appear to have a similar option for enabling -z
now by default.

Subject: [PATCH] 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.

Subject: [PATCH] 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.

Subject: [PATCH] riscv: disable multilib support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From the musl wiki [1]:
musl does not support sharing an include directory between archs
[…], and thus is not compatible with GCC-style multilib. It is
recommended that distributions build GCC with multilib disabled,
and use library directories named lib, not lib64 or lib32.
For this reason, we patch existing GCC configuration files (gcc/config)
to pin MULTILIB_OSDIRNAMES to lib, there is also a corresponding GCC
upstream bug about this issue [2]. Avoiding the use of lib64 and lib32
directories is a bit more difficult on the RISC-V architecture. This is
due to the fact that the default RISC-V configuration does not only use
the lib64 and lib32 directories but also subdirectories within these
directories for different RISC-V ABIs (e.g. lp64d, lp64, …) [3].
This patch aligns the RISC-V configuration with other architectures by
pinning MULTILIB_OSDIRNAMES to lib for rv64gc (our default RISC-V
-march). Furthermore, this patch removes the ABI-specific startfile
prefix spec. Since both of these impact the default LIBRARY_PATH [4]
this patch thereby aligns the default RISC-V LIBRARY_PATH with that from
other Alpine architectures and thereby fixes #13369 [5].
Incidentally, this also fixes gccgo on riscv64, as without this patch
gccgo is otherwise not able to find the *.gox files for the Go standard
library.

Subject: [PATCH] configure: fix detection of atomic builtins in libatomic
configure script
Alpine's --enable-autolink-libatomic (which is enabled for riscv64 by
default) causes the libatomic configure script to incorrectly detect
which builtins are available on riscv64. This then causes incorrect code
generation for libatomic since it assumes compiler builtins to be
available which are not actually available on riscv64.
This commit fixes this issue by disabling linking of libatomic configure
test code entirely, thereby preventing linking against libatomic.
See:
* https://gitlab.alpinelinux.org/alpine/aports/-/issues/12948
* https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101996#c6

Subject: [PATCH] static PIE: ensure -static reaches the linker
on some targets, the logic for the compiler option -static seems not
to be processed when -pie is present. rather than playing
whack-a-mole, just ensure LD_PIE_SPEC specs always pass -static to ld
if either -static or -static-pie is present on the compiler driver
command line.
this may produce redundant -static arguments but it doesn't matter.

From 4c8cc9a8621b91f8aa83d8ca81f22b00a98d9fa9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] except: Don't use the cached value of the gcc_except_table
section for comdat functions [PR119507]
This has been broken since GCC started to put the comdat functions' gcc_except_table into their
own section; r0-118218-g3e6011cfebedfb. What would happen is after a non-comdat function is processed,
the cached value would always be used even for comdat function. Instead we should create a new
section for comdat functions.
OK? Bootstrapped and tested on x86_64-linux-gnu.
PR middle-end/119507
gcc/ChangeLog:
* except.cc (switch_to_exception_section): Don't use the cached section if
the current function is in comdat.
gcc/testsuite/ChangeLog:
* g++.dg/eh/pr119507.C: New test.

View file

Provide struct_sock_fprog_sz on Linux, rather than on Linux+glibc.
With `#include <linux/filter.h>` `struct sock_fprog` is available when
linux headers are available. It seems that glibc is just including that header
as an implementation detail, while musl does not.

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.

# DP: Retry the build on an ice, save the calling options and preprocessed
# DP: source when the ice is reproducible.
2004-01-23 Jakub Jelinek <jakub@redhat.com>
* gcc.c (execute): Don't free first string early, but at the end
of the function. Call retry_ice if compiler exited with
ICE_EXIT_CODE.
(retry_ice): New function.
* diagnostic.c (diagnostic_count_diagnostic,
diagnostic_action_after_output, error_recursion): Exit with
ICE_EXIT_CODE instead of FATAL_EXIT_CODE.

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.
Backport from mainline

* config/i386/i386.c (ix86_frame): Moved to ...
* config/i386/i386.h (ix86_frame): Here.
(machine_function): Add frame.
* config/i386/i386.c (ix86_compute_frame_layout): Repace the
frame argument with &cfun->machine->frame.
(ix86_can_use_return_insn_p): Don't pass &frame to
ix86_compute_frame_layout. Copy frame from cfun->machine->frame.
(ix86_can_eliminate): Likewise.

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.

From 61bb7f0e152ce5be700a44007d036ea0de4b254d Mon Sep 17 00:00:00 2001
From: "H.J. Lu" <hjl.tools@gmail.com>
Date: Sat, 6 Jan 2018 22:29:56 -0800
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".

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.
git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/gcc-7-branch@257067 138bc75d-0d04-0410-961f-82ee72b054a4
