This series of patches adds glibc support for MicroBlaze architecture.
The first patch adds the microblaze glibc/ports component.
The second patch will be forwarded to libc-alpha, as it adds
microblaze relocations to elf/elf.h
The final patch is the latest version of config.sub from the upstream
repo (config.guess hasnt moved) and adds support for microblaze-xilinx
targets.
Thanks,
David

Thanks for the new port!
I just wanted to set the expectation here.
We are in the middle of the 2.17 code freeze.
The master branch will likely thaw at the
start of Janaury once 2.17 goes out and open
for 2.18 development.
We can still work on reviewing your patches,
but keep in mind that our resources are
focused on the current 2.17 release.
To start off with what is your FSF copyright
status?
Cheers,
Carlos.

You don't give any background or rationale for the design choices you
made. There are several things in this submission that don't generally
make sense for new ports.
You need to say how the port was tested. Do you have any compilation
warnings (building with GCC 4.7 or later)? If so, you need to make sure
they are architecture-independent, or do not relate to any issue with the
port itself. Do you have any testsuite failures? If so, what tests fail,
and why?

First some general comments about things missing from the port:
* You don't have a shlib-versions file. A new port should generally set
the minimum symbol version to that of the next glibc release, so either
GLIBC_2.17 or GLIBC_2.18 depending on when this port gets in, which is
done with a DEFAULT line in a shlib-versions file.
* You don't have a kernel-features.h file. There are various features
that the generic kernel-features.h file only enables for particular
architectures, not unconditionally for all kernels with a certain version
or later. As for other architectures, you need to go through all those
macros and define them in the MicroBlaze kernel-features.h for the
relevant kernel.org kernel versions in which the feature was added
(unconditionally, if the feature was present for MicroBlaze in kernel
2.6.30 when MicroBlaze support was added).
* You don't have a libm-test-ulps file, and should add one. A review of
test results should have shown that such a file was missing.
* You don't have a sotruss-lib.c file, and should add one. A review of
compiler warnings should have shown that such a file was missing.
* You don't have a tst-audit.h file, and should add one.
Now more specific comments on the changes:

Comments (which should end with ".") should not just repeat the plain
meaning of the source code. Instead, explain *why* a frame pointer is
needed (on this architecture).

I don't think it's a good idea to put this sort of thing in sysdeps files;
certainly not when you need to name every library, probably including new
ones as and when added to glibc.
Instead, note that on x86_64, for example, the installed libc.so linker
script contains:
GROUP ( /lib64/libc.so.6 /usr/lib64/libc_nonshared.a AS_NEEDED ( /lib64/ld-linux-x86-64.so.2 ) )
I think we should make all the miscellaneous shared libraries and .so
files be linked more like normal libraries linked with a shared glibc
after installation. That is, --start-group libc.so libc_nonshared.a
--as-needed ld.so --no-as-needed --end-group. And with that change,
remove all the miscellaneous rules in various makefiles (sysdeps and
otherwise) to link this or that library with ld.so or libc_nonshared.a.
That sort of architecture-independent change does have risks that would
put it off past 2.17 now we're in the freeze, but it seems the right way
to do this rather than duplicating a long list of libraries in sysdeps
files.

Will not be needed when you use GLIBC_2.18 in shlib-versions; functions
from libgcc should only be exported like this for backwards binary
compatibility in very old ports that have been around since 2.0.

Likewise. The comment about MIPS also seems suspicious. And, since you
define exceptions and rounding modes, you need implementations of the fe*

Given the use of GLIBC_2.18 versions, compatibility with any legacy

That's not how bits/fcntl.h files using fcntl-linux.h should work.

2.6.16 is the global minimum now, you should use 2.6.30 or newer since

Where the i386 file you're including says "Consider moving to

Thanks very much for the comments. The MicroBlaze port has existed out of tree for quite
some time, and as such we've missed some of the changes which occurred upstream for
other ports. I'll address your comments in an updated version of this patch.
I appreciate that the testing for 2.17 release is a busy period, so we'll be grateful for any
progress that can be made here towards inclusion.
thanks again,
David

Being in the ports/ tree is no different from being a separate add-on port.
So you can update your code and test it against the trunk that way.
For the items where Joseph suggested the clean solutions would involve some
change to the main tree, you can work on each of those patches and post it
without delay. We'll decide case-by-case whether each one is safe enough
to commit during the freeze. elf.h additions will be fine, for example.
If it turns out that all the changes you need outside your own port are
safe enough to let in during the 2.17 freeze, then your port can make 2.17
too. But we'll have to take it one change at a time and see how it goes.
Thanks,
Roland
