[PATCH 0/13] Add musl support to GCC
2015-05-08 Szabolcs Nagy <szabolcs.nagy@arm.com>
* config/glibc-stdint.h (OPTION_MUSL): Define.
(INT_FAST16_TYPE, INT_FAST32_TYPE, UINT_FAST16_TYPE, UINT_FAST32_TYPE):
Change the definition based on OPTION_MUSL for 64 bit targets.
* config/linux.h (OPTION_MUSL): Redefine.
* config/alpha/linux.h (OPTION_MUSL): Redefine.
* config/rs6000/linux.h (OPTION_MUSL): Redefine.
* config/rs6000/linux64.h (OPTION_MUSL): Redefine.

This patch brings over a few features from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
* -Werror-maybe-reset
Has the effect of -Wno-error if GCC_NO_WERROR is
set and not '0', a no-operation otherwise. This is
to be able to use -Werror in "make" but prevent
GNU autoconf generated configure scripts from
freaking out.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

I talked to Andrew about what files he changed in GCC and created and
tested this new patch. Andrew also mentioned changing some assembly
files in glibc but I don't see any use of '.section .note.GNU-stack' in
any assembly files in glibc (for any platform) so I wasn't planning on
creating a glibc to add them to mips glibc assembly language files.
OK to check in this patch?

This patch brings over a few features from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
* -Werror-maybe-reset
Has the effect of -Wno-error if GCC_NO_WERROR is
set and not '0', a no-operation otherwise. This is
to be able to use -Werror in "make" but prevent
GNU autoconf generated configure scripts from
freaking out.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

I talked to Andrew about what files he changed in GCC and created and
tested this new patch. Andrew also mentioned changing some assembly
files in glibc but I don't see any use of '.section .note.GNU-stack' in
any assembly files in glibc (for any platform) so I wasn't planning on
creating a glibc to add them to mips glibc assembly language files.
OK to check in this patch?

(steal_delay_list_from_target): Change REDUNDANT array from booleans to
RTXes. Call fix_reg_dead_note on every non-null element.
(steal_delay_list_from_fallthrough): Call fix_reg_dead_note on a
redundant insn, if any. (relax_delay_slots): Likewise.
(update_reg_unused_notes): Rename REDUNDANT_INSN to OTHER_INSN.

gcc/musl: rework SSP-support
Make musl provide libssp_nonshared.a and make GCC link it unconditionally
if musl is used. This should be a no-op if SSP is disabled and seems to be
the only reliable way of dealing with SSP over all packages due to the mess
that is linkerflags handling in packages.

gcc: prevent the use of LDRD/STRD on ARMv5TE
These instructions are for 64-bit load/store. On ARMv5TE, the CPU
requires addresses to be aligned to 64-bit. When misaligned, behavior is
undefined (effectively either loads the same word twice on LDRD, or
corrupts surrounding memory on STRD).
On ARMv6 and newer, unaligned access is safe.
Removing these instructions for ARMv5TE is necessary, because GCC
ignores alignment information in pointers and does unsafe optimizations
that have shown up as bugs in various places.

commit 9dc38e48f7a6f88b7ac7bfaced91f53660204e46

Date: Fri Apr 5 12:36:06 2013 +0000
toolchain/gcc: .init and .fini need to pick one ISA
The .init and .fini sections are built by concatenating code
fragments. Putting mips16 code in the middle of a mips32 code block
doesn't work. Make gcc built the magic crt stuff in no-mips16 mode.
This is specific to 4.6-linaro but is probably portable to other gcc
flavors. Adding this to the t-libgcc-mips16 makefile fragment is a
hack not suitable for pushing upstream, but there is no mips/t-linux
or mips/t-uclibc and I am not going to touch gcc/configure for two
lines.

Date: Tue Jul 31 00:52:27 2007 +0000
Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
SVN-Revision: 8256
This patch brings over a feature from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

I talked to Andrew about what files he changed in GCC and created and
tested this new patch. Andrew also mentioned changing some assembly
files in glibc but I don't see any use of '.section .note.GNU-stack' in
any assembly files in glibc (for any platform) so I wasn't planning on
creating a glibc to add them to mips glibc assembly language files.
OK to check in this patch?

gcc: don't clobber stamp-bits with a symlink to itself
Several versions of gcc have an issue in libstdc++v3 where the build may
clobber stamp-bits with a link to itself. This doesn't manifest itself
on all systems. On several Ubuntu systems, this doesn't appear to be a
problem, but it is an issue on Fedora 16 systems.
To fix the issue, we'll simply filter out stamp-bits from the symlinks
to be generated.
Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
there.

Subject: [PATCH] gotools: fix compilation when making cross compiler
libgo is "the runtime support library for the Go programming language.
This library is intended for use with the Go frontend."
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
the linker will complain that it cannot find it. That's because shared libgcc
is not present in the install directory yet. libgo.so was made without problem
because gcc will emit -lgcc_s when compiled with -shared option. When gotools
were being made, it was supplied with -static-libgcc thus no link option was
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
for linking with libgo.so
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
available after gcc pass2 completed and will meet the gotools link requirement
at gcc pass3

Make musl provide libssp_nonshared.a and make GCC link it unconditionally
if musl is used. This should be a no-op if SSP is disabled and seems to be
the only reliable way of dealing with SSP over all packages due to the mess
that is linkerflags handling in packages.

gcc: prevent the use of LDRD/STRD on ARMv5TE
These instructions are for 64-bit load/store. On ARMv5TE, the CPU
requires addresses to be aligned to 64-bit. When misaligned, behavior is
undefined (effectively either loads the same word twice on LDRD, or
corrupts surrounding memory on STRD).
On ARMv6 and newer, unaligned access is safe.
Removing these instructions for ARMv5TE is necessary, because GCC
ignores alignment information in pointers and does unsafe optimizations
that have shown up as bugs in various places.
