The gcc default, bss-plt, will cause errors when using the prelinker. All
other distributions that I am aware of are using the the secure-plt. For an
explanation of the differences, the gcc docs:
Current PowerPC GCC accepts a `-msecure-plt' option that generates code
capable of using a newer PLT and GOT layout that has the security
advantage of no executable section ever needing to be writable and no
writable section ever being executable. PowerPC ld will generate this
layout, including stubs to access the PLT, if all input files (including
startup and static libraries) were compiled with `-msecure-plt'.
`--bss-plt' forces the old BSS PLT (and GOT layout) which can give
slightly better performance.
The security of the new PLT and ability to run the prelinker outweigh
any performance penalty.
The secure-plt is enabled by default. The old bss-plt can be enabled by
selecting 'bssplt' in the DISTRO_FEATURES.

Various pieces of the code assume that the --sysroot option gets passed
into the compiler tools. By having a "sane" default, we don't always
spot when this occurs and this can later show up as breakage in sstate,
or in usage of the external toolchain.
We've long since talked about poisoning the default such that it will
break unless the correct option is specified. This patch does just that.
If this patch causes something to fail to build, it most likely means
the various compiler flags and commands are not correctly being passed
through to the underlying piece of software and that there is a real
problem that needs fixing, its not the fault of this patch.

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.

This variable is used to ensure the proper version of --with-float=FOO
is passed to gcc's configure script. gcc also has a --with-fpu=FOO
option that means something different. To avoid confusion, change the
names to be consistent.

Consistent use of whitespace in multi-line assignment, with special
focus on OECONF modifications. Quotes on separate lines, four-space
indentation, one value per line.

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

This allows them to co-exist together in the native sysroot, with one

Its useful to separate out the native (cross) binaries from the target
compilation. We already do this for libgcc, this now takes the same
approach for -initial.

If sstate-inputdirs and sstate-outputdirs don't match with ending '/'
characters, the manifest file can end up corrupted. This change
ensures the metadata is consistent in ending do_populate_root tasks
with this character to avoid manifest file corruption.

The removal of gcc-cross-intermediate inadvertently reintroduced a
problem with the limits.h file being incorrectly/inconsistently
generated.
http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=b0faebd1f07e1616004bd19664395932e7c2c48f
reverted part of:
http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=c8815d2f21849deb9359706f54dc71490773415e
This reintroduces the protected sysroot ensuring the limits.h file is
always correctly generated. To reproduce the bug, build gcc-cross, then
rebuild gcc-cross-initial and it will reference the limits.h file from
gcc-cross in the sysroot.

Now glibc can be compiled with gcc-cross-initial therefore prepare
the stage to drop gcc-cross-intermediate
Also drop arm-nolibfloat.patch should not be needed anymore
half of changes in this patch are meant for OABI which we dont
use anymore

If we don't do this, a stale limits.h may be detected in STAGING_DIR_TARGET
which would result in a different limits.h getting generated by gcc-cross-initial
that references it. The referenced limits.h will then not get found by eglibc-initial
causing rather strange build failures.
The simplest solution is to create a temporary sysroot containing only the things
gcc-cross-initial should care about and this results in a correct limits.h file
regardless of what else may have been built.

currently gcc installs a limits.h which references to another
limits.h which it expects from target sysroot and that header
in target sysroot will come from eglibc. So we need to break
this catch-22 and hence we install a self sufficient limits.h
which is then happy when referenced and doesnt complain about
missing limits.h from target sysroot.
This is mostly used when eglibc-initial configure is run

If EXTRA_OECONF_FPU is left set, certain ARM variables related to hard-float
can get pulled in and trigger rebuilds of the crosssdk code. The best solution
is to simply force the variable to a known correct value for the SDK targets
currently supported in the same way as TARGET_FPU.
There is some slight rearrangement of the gcc code to ensure the variable is
always used to call the fpu function.

this option by default points to /usr/local no matter
what so we cant let it sit on sidelines otherwise it
will access host machine's /usr/local which may not
be desired. So disable this option. This also helps in making
gcc's shared state more consistent

Currently we stash the libgcc install tree and then reuse that
to populate libgcc recipe later. This mechanism does not work
for gcc 4.7/trunk since now libstdc++ needs access to build tree
of libgcc. This patch stashes the gcc-cross build tree
and then reuses this in libgcc as well as in gcc-runtime
recipe builds.
Now we build libgcc in the libgcc recipe instead of just
using the prebuilt install tree

Right now for cross recipes e.g. gcc-cross and binutils-cross
we specify --disable-nls .... --enable-nls on configure cmdline
the --enable-nls coming from gettext bbclass.
So we disable nls for all cross inheriting recipes in gettext
bbclass and then we remove the extra --disable-nls in gcc-cross
and binutils-cross
This patch needs testing. Please help

We force the C locale when running builds for determinstic error messages. We
therefore have no need to NLS support in binutils cross or gcc cross.
We also don't need the standard base/autotools dependencies for our
toolchain components since we don't autoreconf these.
This patch turns off nls and cleans up some of the dependencies resulting
in a slightly less convoluted set of build dependencies.

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.
The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.
Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.
