qemu can freeze and stop responding if the socket buffer connected to a tcp
serial connection fills up. This happens of course when the reader of
the serial data doesn't actually read it.
This happened in the qemurunner code, because after checking for the
"login:" sentinel, data was never again read from the serial connection.
This patch solves the potential freeze by adding a thread to continuously
read the data from the console and log it. So it also will give a full log
of the console, rather than just up to the login prompt.
To simplify this patch, another serial port was also added to use for the
sole purpose of watching for the sentinel as well as being the interactive
serial port. This will also prevent the possibility of lots of debug
data on the console preventing the sentinel value from being seen due to
interleaved text.

neither the TARGET_ARCH nor the TRANSLATED_TARGET_ARCH. So let's drop

Use i686 as TARGET_ARCH for 32bit core2 (and corei7 and atom) builds.
In most cases, i586 and i686 are equivalent values for TARGET_ARCH, however
one important exception is glibc. When configured for i686, glibc enables
optimised string functions (SSE, SSE2, etc), which are not used when
building for i586.
The benefits of i686 optimised string functions vary depending on the
application and the CPU, however in some cases the improvements are
significant. In one test, a 50% increase in FPS was seen when running the
'smashcat' benchmark [1] in a qtwebkit browser on an Intel Atom based SoC.
The gain seems to comes from a 3x improvement in memcpy performance when
copying graphics buffer lines (5120 bytes, or 1280 x 4 bytes/pixel), from
the CPU to GPU. Note that very large memcpy's (e.g. 32MB) on the same
machine show no particular performance increase between i586 and i686.
[1] http://www.smashcat.org/av/canvas_test/
Warning: The change in TARGET_ARCH means that _i586 architecture specific
over-rides will no longer take effect. Both oe-core and meta-oe have been
updated to replace _i586 over-rides with _x86, however other layers may
still need review and updating.

[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.

Only one of the mips64-n32 or mips64 toolchains is built. Causing the
other to be unavailable. This is due to both recipes ending up with the

The toolchain uses the TRANSLATED_TARGET_ARCH in it's name, however the

Avoid this conflict by adding the ABIEXTENSION to the name.

The following patch also passes a "--with-cpu=e300c3" argument to GLIBC.
For this to have any effect the sqrt/sqrtf implementations added by the

The tune-x86_64.inc file is conceptually flawed. x86_64 is more akin to
the x86 and x86-32 ABIs defined in arch-x86.inc than it is a concrete
tune file, such as i586 or core2 - to the extent that everything but the
default tune is defined in the arch-x86.inc file. This becomes very
apparant when attempting to include tune-x86_64.inc in the x86 tune
hierarchy.
Remove the tune-x86_64.inc tune file in favor of it being an ABI
definition in arch-x86.inc and relying on the linear hierarchy of
concrete cpu-types in tune-i586, tune-core2, and tune-corei7.
core2_64 should suffice in lieu of x86_64 for all but a couple esoteric
corner cases involving older pre-core2 CPUs. In these cases, if they
exist at all, the BSP can replace the include tune-x86_64.inc with
arch-x86.inc and set the default tune to x86_64.

cpu-type described in the tune-core2 file.
From the GCC(1):
Intel Core i7 CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3,
SSSE3, SSE4.1 and SSE4.2 instruction set support.
This offers optimizations for Nehalem and Silvermont (e.g. Bay Trail)
CPUs (and beyond).

Core2 has both a 32b and a 64b variant. Currently, core2 implies 32b,
while core2_64 is the 64b version. This implicit 32b mode will become
confusing in later architectures, such as corei7, where it would be
natural for people to assume "corei7" meant 64 bit.
Rather than carrying forward an implicit 32b mode and rather than
changing the naming scheme part way through the architecture hiearchy,
make the 32b and 64b variant explicit in the tune name by changing core2
to core2-32. This patch also standardises on using '-' in the names.

Inherit the PACKAGE_EXTRA_ARCHS from i586 and only explicitly add core2
here.

-march specifies which ISA to use. -mtune specifies which cpu-type to
optimize instruction ordering for, but not which ISA to use. There are
times when it may make sense to specify mtune=generic and use a more
specific march, such as core2, but the opposite makes little sense at
all: use cpu-type specific ISA, but order the instructions
generically. While the -mtune is implied by -march, gcc does not verify
it is using -mtune=core2 with:
gcc -Q -march=core2 --help=target
Explicitly specify -mtune=core2 to be sure.
Add a comment header describing the CPUs targeted by this tune file.
