musl e.g. is configured to not use fixed-include
which is an improvement btw. but libgcc-initial configure
has tests which probe for limits.h and since we put
it in include-fixed/ dir and that dir does not appear
in gcc's internal default search path the configure tests
for CPP detection fail and libgcc-initial can not be compiled.

The gcc-runtime recipe builds the gcc libraries including libstdc++ with
$TARGET_CC_ARCH flags, which include -march=FOO flags that affect
whether atomic instructions are available. This causes an ABI
incompatibility when the compiler by default generates code for less
capable architectures. For example, gcc-runtime libraries on a
Cortex-A8 are built with a different C++11/C++14 mutex implementation
than is used code compiled outside OE and without architecture-specific
flags.
This commit fixes the problem specifically for ABI issues related to
atomic instructions available in ARMV6 and subsequent architectures.
Other ABI incompatibilities may remain in other architectures.

A long-standing bug in gcc turns out to cause problems with unpatched
Linux versions due to improved optimization enabled by gcc 4.9. The
upstream fix missed the gcc-4.9.1 cut-off. It's also been applied
upstream to the 4.8 branch so is being added for OE's 4.8 as well.

0037-gcc-4.8-PR56797.patch was originally added as an OE backport during
4.8.0. Upstream merged it in 4.8.1, and it was present in 4.9.0.
The original patch still applies to 4.9.1 (and presumably 4.8.2), but
now is modifying store_multiple_sequence instead of
load_multiple_sequence (the two functions are nearly identical). It may
or may not be necessary in store_multiple_sequence, but absent a bug
report upstream supporting its application in this case, or a least an
updated comment and upstream status in the patch, I think this patch
should be dropped.

We already indicate our intentions to use ld.bfd by
specifying it in configure using --with-ld which works
ok unless here where we manually create symlinks to
binutils-cross components, when we use ld-is-gold feature
default ld points to gold and this symlinking has to be
aware of the fact that we configured binutils and gcc-cross to use
gold as default ld but gcc-cross-initial uses BFD ld
This would be visible when using gold and rebuilding
eglibc

Fix an issue on a multilib configuration that contains more then 1 multilib.
I.e. on MIPS64:
DEFAULTTUNE = "mips64"
MULTILIBS = "lib32n:mips64_n32 lib32:mips32"
While normally you'd use 'libn32', the above is legal.
With the startswith code, the system will look to expand the 'lib32' element
and find the 'lib32n' instead, and will result in a warning:
lib32 doesn't have a corresponding tune. Skipping...

The gcc-ar.o, gcc-nm.o, gcc-ranlib.o and errors.o included
config.h which was a generated file. But no explicity rule
to clarify the dependency. There was potential building
failure while parallel make.
For gcc-ar.o, gcc-nm.o and gcc-ranlib.o, they were compiled from one C
source file gcc-ar.c, we add them to ALL_HOST_BACKEND_OBJS, so the
'$(ALL_HOST_OBJS) : | $(generated_files)' rule could work for these
objects.
For errors.o, it is part of gengtype, and the gengtype generator program
is special: Two versions are built. One is for the build machine, and one
is for the host. We refered what gengtype-parse.o did (which also is part
of gengtype).

In subdir 'gcc', Most C source files included config.h which was
generated by a rule. But no related prerequisites was added to
the C source compiling rule. There was potential building failure
while makefile enabled parallel.
The C source compiling rule used suffix rule '.c.o', but the suffix
rule doesn't support prerequisites.
https://www.gnu.org/software/make/manual/html_node/Suffix-Rules.html
We used the pattern rule '%.o : %.c' to instead, and add the config.h
as its prerequisite
We also moved the '%.o : %.c' rule down to the 'build/%.o :' rule, which
makes '%.o : %.c' rule doesn't override 'build/%.o :'.

MULTILIB_OPTIONS takes the parameters which trigger a given multilib to be
selected. It supports *one* option per multilib, '/' separated. Spaces
separate options used to generate additional multilib combinations.
Adding in all of CFLAGS to this is therefore clearly a really bad idea
but how do we fix things?
The best option I've come up with so far is a list of whitelist variables
to use to trigger the multilibs. Its populated with the standard multilibs
we support, anyone setting up an advanced multilib can populate the variable
with the correct trigger parameters.
This has the advantage of simplifying the code and allowing us to remove
the code filtering blocks since there is no longer option duplication. Testing
after this change shows a much improved sdk toolchain functionality.

It was observed that code using STLport 4.6 fails to compile under the
SDK with the following error message:
.../includes/cstddef:38:46: fatal error: ../4.7.2/cstddef: No such file
or directory
STLport 4.6 (screwily) assumes that the C++ system headers live in a
gcc-versioned subdirectory, for gcc>=3.0; cf
http://sourceforge.net/p/stlport/code/ci/STLport-4.6-patch/tree/stlport/config/stl_gcc.h#l269.
This assumption is *almost always* valid, because that matches the
default setting of --with-gxx-include-dir. We can match that behavior by
appending "/${BINV}" to our own --with-gxx-include-dir settings.

When enabling a lib32-gcc in a 64 bit build, without doing any
other configuration, the mutilib dir is unspecified, which is
represented internally in gcc as "." and as such uncovers an
invalid free on a non-malloc'd pointer.
As suggested by the gcc folks, simply make sure the "." case
is also stored in a malloc'd pointer, so that the intended
runtime behaviour of the code remains unchanged.
Patch has been accepted by upstream maintainers of gcc.

The gengtype patch we apply to gcc aims to ensure that the build and host
config headers don't get confused. We're seeing build failures where
both headers have been included, likely due to a race over the configuration
files.
It seems the gengtype-lex.c file isn't being regenerated when it should
and the unconditional inclusion of bconfig.h is resulting in these issues.
The fix is therefore to remove the file, forcing its regeneration.

The do_configure_prepend was duplicated in gcc-4.X.inc and
gcc-configure-common.inc leading to confusion when reading the resulting
do_configure task where the file was processed twice.
The only difference was the removal of the include line for gcc 4.8/4.9.
On mingw were were seeing two issues, firstly that the if statements meant
the values we wanted weren't being set, the second that the include
paths were still wrong as there was no header path set.
To fix the first issue, the #ifdef conditionals were removed, we want
to set these things unconditionally. The second issue is addressed by
setting the NATIVE_SYSTEM_HEADER_DIR variable here (it was already
set in t-oe).

There is a fix about to go into bitbake to ensure that datastores
being accessed with a name other than "d" are correctly reflected
in checksums. This will cause this function to add in a number of
dependencies we don't want.
These do need to be properly unravelled in due course but would
only really affect multilib builds. For now therefore just exclude
the variables as per the old behaviour.

The class itself currently does nothing. The idea is to mark all recipes that
make use of the texinfo utilities. In the future, this class could be used to
suppress the generation/formatting of documentation for performance,
explicitly track dependencies on these utilities, and eliminate Yocto's
current dependency on the host system's texinfo utilities.

Within the OE build environment, we supply the correct fpu settings. These
only need to be spelt out for the on-target gcc.
Doing this means the checksums for the core compiler don't depend on the fpu
settings. We exclude the compiler tunes for similar reasons, it doesn't need
to influence the compiler build.

As far as I can tell this variable is now completely unneeded. It would
only ever get used in target builds and these are now correctly done
in the target environment namespace, not any of our cross environments.
As such, CC and other variables contain the correct compilers and other
tune options and these are correctly picked up when building libgcc,
libstdc++ and others.
I tried to figure out where else these would make any sense and couldn't
find anything. Builds appear fine without them so lets drop the complexity
including the patch adding in this flag to gcc.

This command modifies ${S} and can race against other tasks running do_configure and
having the scripts disappear from under them. To avoid this move to its own
task and work on the shared work directory as a common task.

Currently the gcc builds are building copies of the target libraries
that we never use (it isn't installed in do_install). This is a rather
pointless waste of cpu time.
Instead just compile the host targets. Comparing the package output of
this compared to a previous build shows that the unwind.h header is
missing since its provided by gcc. Fix this simply by copying it in.

Rather than building the whole of libgcc to obtain the unwind.h header
