gcc: Drop 5.4 series

We now have gcc 6 and gcc 7 recipes, the gcc 5 series can be dropped
as we're no longer going to support it for targets.

Subject: [PATCH 11/46] gcc-poison-dir-extend
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 12/46] gcc-4.3.3: SYSROOT_CFLAGS_FOR_TARGET
Before committing, I noticed that PR/32161 was marked as a dup of PR/32009, but my previous patch did not fix it.
This alternative patch is better because it lets you just use CFLAGS_FOR_TARGET to set the compilation flags for libgcc. Since bootstrapped target libraries are never compiled with the native compiler, it makes little sense to use different flags for stage1 and later stages. And it also makes little sense to use a different variable than CFLAGS_FOR_TARGET.
Other changes I had to do include:
- moving the creation of default CFLAGS_FOR_TARGET from Makefile.am to configure.ac, because otherwise the BOOT_CFLAGS are substituted into CFLAGS_FOR_TARGET (which is "-O2 -g $(CFLAGS)") via $(CFLAGS). It is also cleaner this way though.
- passing the right CFLAGS to configure scripts as exported environment variables
I also stopped passing LIBCFLAGS to configure scripts since they are unused in the whole src tree. And I updated the documentation as H-P reminded me to do.
Bootstrapped/regtested i686-pc-linux-gnu, will commit to 4.4 shortly. Ok for 4.3?

Subject: [PATCH 13/46] 64-bit multilib hack.
GCC has internal multilib handling code but it assumes a very specific rigid directory
layout. The build system implementation of multilib layout is very generic and allows
complete customisation of the library directories.
This patch is a partial solution to allow any custom directories to be passed into gcc
and handled correctly. It forces gcc to use the base_libdir (which is the current
directory, "."). We need to do this for each multilib that is configured as we don't
know which compiler options may be being passed into the compiler. Since we have a compiler
per mulitlib at this point that isn't an issue.
The one problem is the target compiler is only going to work for the default multlilib at
this point. Ideally we'd figure out which multilibs were being enabled with which paths
and be able to patch these entries with a complete set of correct paths but this we
don't have such code at this point. This is something the target gcc recipe should do
and override these platform defaults in its build config.

Subject: [PATCH 14/46] optional libstdc
gcc-runtime builds libstdc++ separately from gcc-cross-*. Its configure tests using g++
will not run correctly since by default the linker will try to link against libstdc++
which shouldn't exist yet. We need an option to disable -lstdc++
option whilst leaving -lc, -lgcc and other automatic library dependencies added by gcc
driver. This patch adds such an option which only disables the -lstdc++.
A "standard" gcc build uses xgcc and hence avoids this. We should ask upstream how to
do this officially, the likely answer is don't build libstdc++ separately.

While compiling gcc-crosssdk-initial-x86_64 on some host, there is
occasionally failure that test the existance of default.h doesn't
work, the reason is tm_include_list='** defaults.h' rather than
tm_include_list='** ./defaults.h'
So we add the test condition for this situation.

Subject: [PATCH 20/46] cpp: honor sysroot.
Currently, if the gcc toolchain is relocated and installed from sstate, then you try and compile
preprocessed source (.i or .ii files), the compiler will try and access the builtin sysroot location
rather than the --sysroot option specified on the commandline. If access to that directory is
permission denied (unreadable), gcc will error.
This happens when ccache is in use due to the fact it uses preprocessed source files.
The fix below adds %I to the cpp-output spec macro so the default substitutions for -iprefix,
-isystem, -isysroot happen and the correct sysroot is used.

Subject: [PATCH 22/46] Define GLIBC_DYNAMIC_LINKER and UCLIBC_DYNAMIC_LINKER
relative to SYSTEMLIBS_DIR
This patch defines GLIBC_DYNAMIC_LINKER and UCLIBC_DYNAMIC_LINKER
relative to SYSTEMLIBS_DIR which can be set in generated headers
This breaks the assumption of hardcoded multilib in gcc
Change is only for the supported architectures in OE including
SH, sparc, alpha for possible future support (if any)
Removes the do_headerfix task in metadata

Subject: [PATCH 23/46] gcc: Fix argument list too long error.
There would be an "Argument list too long" error when the
build directory is longer than 200, this is caused by:
headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u`
The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle
it, use the $(sort list) of GNU make which can handle the too long list
would fix the problem, the header would be short enough after sorted.
The "tr ' ' '\012'" was used for translating the space to "\n", the
$(sort list) doesn't need this.

Subject: [PATCH 24/46] Disable sdt.
We don't list dtrace in DEPENDS so we shouldn't be depending on this header.
It may or may not exist from preivous builds though. To be determinstic, disable
sdt.h usage always. This avoids build failures if the header is removed after configure
but before libgcc is compiled for example.

Subject: [PATCH 25/46] libtool
libstdc++ from gcc-runtime gets created with -rpath=/usr/lib/../lib for qemux86-64
when running on am x86_64 build host.
This patch stops this speading to libdir in the libstdc++.la file within libtool.
Arguably, it shouldn't be passing this into libtool in the first place but
for now this resolves the nastiest problems this causes.
func_normal_abspath would resolve an empty path to `pwd` so we need
to filter the zero case.

Subject: [PATCH 26/46] gcc: armv4: pass fix-v4bx to linker to support EABI.
The LINK_SPEC for linux gets overwritten by linux-eabi.h which
means the value of TARGET_FIX_V4BX_SPEC gets lost and as a result
the option is not passed to linker when chosing march=armv4
This patch redefines this in linux-eabi.h and reinserts it
for eabi defaulting toolchains.
We might want to send it upstream.

Subject: [PATCH 29/46] export CPP
The OE environment sets and exports CPP as being the target gcc. When
building gcc-cross-canadian for a mingw targetted sdk, the following can be found
in build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log:
configure:3641: checking for _FILE_OFFSET_BITS value needed for large files
configure:3666: gcc -c -isystem/media/build1/poky/build/tmp/sysroots/x86_64-linux/usr/include -O2 -pipe conftest.c >&5
configure:3666: $? = 0
configure:3698: result: no
configure:3786: checking how to run the C preprocessor
configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32
configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
configure:3876: $? = 0
Note this is a *build* target (in build-x86_64-linux) so it should be
using the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32
headers are very different, using the wrong cpp is a real problem. It is leaking
into configure through the CPP variable. Ultimately this leads to build
failures related to not being able to include a process.h file for pem-unix.c.
The fix is to ensure we export a sane CPP value into the build
environment when using build targets. We could define a CPP_FOR_BUILD value which may be
the version which needs to be upstreamed but for now, this fix is good enough to
avoid the problem.

Subject: [PATCH 30/46] Enable SPE & AltiVec generation on powepc*linux target
When is configured with --target=powerpc-linux, the resulting GCC will
not be able to generate code for SPE targets (e500v1/v2).
GCC configured with --target=powerpc-linuxspe will not be able to
generate AltiVec instructions (for e6500).
This patch modifies the configured file such that SPE or AltiVec code
can be generated when gcc is configured with --target=powerpc-linux.
The ABI and speciffic instructions can be selected through the
"-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters.

Subject: [PATCH 31/46] Disable the MULTILIB_OSDIRNAMES and other multilib
options.
Hard coding the MULTILIB_OSDIRNAMES with ../lib64 is causing problems on
systems where the libdir is NOT set to /lib64. This is allowed by the
ABI, as
long as the dynamic loader is present in /lib.
We simply want to use the default rules in gcc to find and configure the
normal libdir.

Subject: [PATCH 32/46] Ensure target gcc headers can be included
There are a few headers installed as part of the OpenEmbedded
gcc-runtime target (omp.h, ssp/*.h). Being installed from a recipe
built for the target architecture, these are within the target
sysroot and not cross/nativesdk; thus they weren't able to be
found by gcc with the existing search paths. Add support for
picking up these headers under the sysroot supplied on the gcc
command line in order to resolve this.

Subject: [PATCH 40/46] handle sysroot support for nativesdk-gcc
Being able to build a nativesdk gcc is useful, particularly in cases
where the host compiler may be of an incompatible version (or a 32
bit compiler is needed).
Sadly, building nativesdk-gcc is not straight forward. We install
nativesdk-gcc into a relocatable location and this means that its
library locations can change. "Normal" sysroot support doesn't help
in this case since the values of paths like "libdir" change, not just
base root directory of the system.
In order to handle this we do two things:
a) Add %r into spec file markup which can be used for injected paths
such as SYSTEMLIBS_DIR (see gcc_multilib_setup()).
b) Add other paths which need relocation into a .gccrelocprefix section
which the relocation code will notice and adjust automatically.

Subject: [PATCH 41/46] Search target sysroot gcc version specific dirs with
multilib.
We install the gcc libraries (such as crtbegin.p) into
<sysroot><libdir>/<target-sys>/5.2.0/
which is a default search path for GCC (aka multi_suffix in the
code below). <target-sys> is 'machine' in gcc's terminology. We use
these directories so that multiple gcc versions could in theory
co-exist on target.
We only want to build one gcc-cross-canadian per arch and have this work
for all multilibs. <target-sys> can be handled by mapping the multilib
<target-sys> to the one used by gcc-cross-canadian, e.g.
mips64-polkmllib32-linux
is symlinked to by mips64-poky-linux.
The default gcc search path in the target sysroot for a "lib64" mutlilib
is:
<sysroot>/lib32/mips64-poky-linux/5.2.0/
<sysroot>/lib32/../lib64/
<sysroot>/usr/lib32/mips64-poky-linux/5.2.0/
<sysroot>/usr/lib32/../lib64/
<sysroot>/lib32/
<sysroot>/usr/lib32/
which means that the lib32 crtbegin.o will be found and the lib64 ones
will not which leads to compiler failures.
This patch injects a multilib version of that path first so the lib64
binaries can be found first. With this change the search path becomes:
<sysroot>/lib32/../lib64/mips64-poky-linux/5.2.0/
<sysroot>/lib32/mips64-poky-linux/5.2.0/
<sysroot>/lib32/../lib64/

Subject: [PATCH 42/46] Fix various _FOR_BUILD and related variables
When doing a FOR_BUILD thing, you have to override CFLAGS with
CFLAGS_FOR_BUILD. And if you use C++, you also have to override
CXXFLAGS with CXXFLAGS_FOR_BUILD.
Without this, when building for mingw, you end up trying to use
the mingw headers for a host build.
The same goes for other variables as well, such as CPPFLAGS,
CPP, and GMPINC.

Subject: [PATCH] PR target/65358 Avoid clobbering partial argument during
sibcall
PR target/65358
* expr.c (memory_load_overlap): New function.
(emit_push_insn): When pushing partial args to the stack would
clobber the register part load the overlapping part into a pseudo
and put it into the hard reg after pushing. Change return type
to bool. Add bool argument.
* expr.h (emit_push_insn): Change return type to bool.
Add bool argument.
* calls.c (expand_call): Cancel sibcall optimization when encountering
partial argument on targets with ARGS_GROW_DOWNWARD and
!STACK_GROWS_DOWNWARD.
(emit_library_call_value_1): Update callsite of emit_push_insn.
(store_one_arg): Likewise.
PR target/65358
* gcc.dg/pr65358.c: New test.

Subject: [PATCH] Reuse -fdebug-prefix-map to replace -ffile-prefix-map
The oe-core may use external toolchain to compile,
which may not support -ffile-prefix-map.
Since we use -fdebug-prefix-map to do the same thing,
so we could reuse it to replace -ffile-prefix-map.
