Configuring gcc with --enable-target-optspace (which causes gcc to
append "-g -Os" to the default CFLAGS_FOR_TARGET and so force libgcc
etc target libraries to always be optimised for size) dates back to
the very first commit in oe-core git in 2005 (for gcc 3.4.3).
Configuring gcc with --enable-target-optspace is not done widely
elsewhere (it's not used for Ubuntu or Fedora host gcc, the Linaro
binary toolchain or in Buildroot since early 2015). Sometime around
gcc 4.5.x it caused problems for powerpc and so was disabled for that
architecture:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810
This patch removes --enable-target-optspace completely (ie powerpc is
no longer a special case) and allows optimisation of libgcc etc to be
controlled directly by the flags present in TARGET_CFLAGS.

in a separate meta-nommu layer).

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.

[YOCTO #7230]
In certain system configurations TRANSLATED_TARGET_ARCH will not
expand in the right order for gcc-cross-candian-mips64n32 to be
generated properly.
This will cause SDKs to fail to generate properly.
Changing the global definition of TRANSLATED_TARGET_ARCH always
expands the ABIEXTENSION, which causes the OVERRIDES to pick it up
as well. This effectively defines a new class of overrides for the 'n32'.
The side effect is that we need to duplicate some mips64 overrides, and
redefine others that were previously 'n32' or 'mips64' exclusive to have
the correct semantics.

The current implementation of shared work for gcc is at best confusing. It relies
on the fetch/unpack/patch tasks having exactly the same stamps and if this gets
broken for some reason, its hard to figure out what the problem is. It also
leads to complex code in bitbake.
The benefits of shared work for gcc are clear but a better approach is needed. This
patch adjusts things so that a single new recipe (gcc-source) provides the
fetch/unpack/patch/preconfigure tasks, the rest of gcc simply depends on these tasks
and have no fetch/unpack/patch tasks of their own.
This means we should get the significant benefits (disk usage/performance) of the
single source tree but in a way which has less potential for problems and is
easier for people to understand. The cost is an extra recipe/some inc files
which is probably a good tradeoff.

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.

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.

There were puzzling failures when you make a force recompile of any gcc

being detected in config.log files.
gcc is different in that many of the config.log files are generated during
the do_compile phase. This means this host contamination issue has always
been present but only shows up on a rebuild.
The fix is to force the appropriate configuration variable to "none required"
then gcc won't look in the bad locations.

The fetch/unpack/patch/headerfix tasks are shared and hence their sstate hashes
should also match. Sadly this is not the case since:
a) gcc-runtime applies an additional patch
b) The do_headerfix task was missing from libgcc
c) The do_headerfix task is a shell task and hence depends
on all exported variables which can vary between cross and target
recipes.
To fix this, the patch moves the patch to the common code, adds
the headerfix task to a common include file and disabled shell
dependencies on the do_headerfix task since its clear in this case
we don't need thsoe dependencies since we just call sed.
With this patch applied, all these recipes now share common sstate checksums.

This patch introduces a distro feature which enables gcc to produce
both 32bit and 64bit code, and enables binutils to operate on both
32bit and 64bit binaries. It differs from multilib toolchains in
that it does not require to compile a version of the libc for each
architecture variant. However, the code produced for the secondary
architecture will not be linkable against the libc.
v2: - Renamed the feature name from "biarch" to "multiarch". The GCC
installation manual claims that the mips-linux can be made a tri-arch
compiler (http://gcc.gnu.org/install/configure.html)
- For x86_64, the compiler is made bi-arch by default, so nothing
has to be done in particular.
- I analyzed the gcc/config.gcc from GCC sources and added in this
patch all the architectures that could be made biarch with the version
of gcc currently used in OE, which are powerpc, and sparc, in addition
to x86. mips and s390 will probably be supported in future versions of
gcc. For x86 and sparc, only the --enable-targets=all option is valid
to make this work (this option doesn't have any other side effects than
making the compiler bi-arch). For powerpc, I used the
--enable-targets=powerpc64 option (although 'all' also works).
Note: - Untested on powerpc and sparc. But I believe it works the same
as with x86.
- gcc in meta-toolchain is also made multiarch.

This patched is derived from Richard, make gcc use the shared source
directory during the different building:
1) Make gcc-cross, gcc-cross-initial, gcc-cross-intermediate and
gcc-runtime share the same source directory.
2) The source directory is ${TMPDIR}/work-shared/gcc-${PV}, for example:
tmp/work-shared/gcc-4.5.1
3) Fix do_clean to clean the shared source directory and stamps
4) gcc uses sed and creates config files against ${S} which means the
directory should not be shared. Change the way to make it work:
* The configure option --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS}
can replace the sed command, see the code in configure:
if test "x$with_headers" != x; then
glibc_header_dir=$with_headers
This has the same effect as the sed command:
sed -i 's:^\([ ]*\)glibc_header_dir=\"${with_build_sysroot}/usr/include\": ...
so add the --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS} to
gcc-configure-cross.inc( not add to gcc-configure-common.inc, since
not all the gcc building need this, the one which has its own do_configure
doesn't need it).
* Move t-oe from ${T} to ${B}/gcc, so that the patched Makefile.in
can read it easily, please see the commit for gcc-4.5.1 and
gcc-4.6.0.
* Use the defaults.h in ${B}/gcc instead of ${S}/gcc, and the patched
configure.ac(configure) can read it correctly, please see the
commit for gcc-4.5.1 and gcc-4.6.0.
* The gcc-crosssdk.inc used sed to edit ${S}/config/*/linux*.h
to change the GLIBC_DYNAMIC_LINKER, which made the source
incompatible. To make the source compatible:
- Use:
sed -i ${S}/gcc/config/*/linux*.h -e \
's#\(GLIBC_DYNAMIC_LINKER[^ ]*\)\( *"/lib.*\)#\1 SYSTEMLIBS_DIR\2#'
so entries in the files that look like:
#define GLIBC_DYNAMIC_LINKER64 "/lib64/ld-linux-x86-64.so.2"
would become
#define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"
and we define SYSTEMLIBS_DIR in defaults.h.
NOTE:
#define GLIBC_DYNAMIC_LINKER64 (SYSTEMLIBS_DIR "/ld-linux-x86-64.so.2")
doesn't work in in the following define:
#define LINUX_DYNAMIC_LINKER \
CHOOSE_DYNAMIC_LINKER (GLIBC_DYNAMIC_LINKER, UCLIBC_DYNAMIC_LINKER)
so use
#define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"
5) Add do_configure_prepend to gcc-configure-common.inc and remove the
one in gcc-crosssdk.inc, this makes it easy to share the source,
otherwise we need do extra changes in gcc-configure-sdk.inc.
6) Use "cat > file <_EOF" to replace the "echo > file"

path, gcc knows whether target (e)glibc implements stack protector itself.
However this breaks meta-toolchain, which actually has target libc headers
installed under {with-build-sysroot}/opt/... This way features.h is not found
and thus gcc-crosssdk-intermediate thinks that target (e)glibc doesn't support ssp.
Later when building eglibc-nativesdk, undefined reference to "__stack_chk_guard"
occurs which was caused by:
o eglibc do_configure found that gcc-crosssdk-intermediate supports ssp,
and thus enable -fstack-protector for nscd
o eglibc itself supports stack smash proctection for some architectures such
as i386, x86-64, etc. It's expected to use its own method to provide stack
protection, instead of relying on gcc. So eglibc rtld.os doesn't export
__stack_chk_guard to other modules
o then when installing nscd objects, gcc-crosssdk-intermediate sees the
flag "-fstack-protector", while it thought this eglibc doesn't implement
ssp itself, so gcc turns to the alternative to find a valid
__stack_chk_guard exported. eglibc doesn'g export it, while
gcc-crosssdk-intermediate itself disables libssp.
Then the undefined reference happens. If enabling libssp for gcc-crosssdk-
intermediate, it may also work-around this issue. But the ideal fix is still
to replace hard coded path with the actual one where target libc gets installed.
glibc-nativesdk doesn't encounter this issue because it thinks gcc doesn't
support ssp, and thus doesn't enable "-fstack-protector" for nscd. Don't know
the reason yet

If not configured with --enable-target-optspace, gcc will report
errors if there is '-Os' optimization in parameters.
This fixes [BUGID #342]
Also add "--enable-target-optspace" option to arm gcc configuration.

Fix one parameter order issue for base_contains function,
which impacts glibc build under new gcc.
Add new judge code to determine whether <altivec.h> is needed.
This fixes the mpeg2dec build failure under new gcc.
Use O2 as the optimization flag to tinylogin as it will meet
segfault if compiled by gcc-4.5.0 when enable both frename-registers
and Os options. Use O2 instead.

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.
