treewide: remove scaled from phoc.ini

Removes the scaled key from phoc.ini, as this should be fixed upstream and not
hacked in downstream configs. Most devices should work with the default
scaling configuration.

+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.

+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

+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

+ -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.

+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:

++# The libatomic configure script performs several checks to determine
++# whether builtins for atomic operations are available. When compiling
++# with --enable-autolink-libatomic the test code compiled by the
++# configure script is also linked against libatomic. This causes it
++# to think that builtins are available, even if there are not, since
++# the tested symbols are provided by libatomic.
++#
++# This is a hack to ensure that we don't link against libatomic by not

+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.

+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.
+

+
+	* g++.dg/eh/pr119507.C: New test.

+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.

+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.

+
+Binutils does not appear to have a similar option for enabling -z

+Date: Fri, 21 Aug 2020 06:50:33 +0000
+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.

+ This seems to be the common case when bootstrapping gcc, the piepatches do

+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:

++# The libatomic configure script performs several checks to determine
++# whether builtins for atomic operations are available. When compiling

+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.

+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.

+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.
