Build failure on treeboot-walnut.c

Build failure on treeboot-walnut.c

[Grant Likely]

Building Paul's current powerpc branch with a ppc6xx compiler causes
the following build failure:

  SYSMAP  System.map
  BOOTCC  arch/powerpc/boot/treeboot-walnut.o
{standard input}: Assembler messages:
{standard input}:184: Error: Unrecognized opcode: `mfdcr'
{standard input}:185: Error: Unrecognized opcode: `mfdcr'

{standard input}:217: Error: Unrecognized opcode: `mtdcr'
make[1]: *** [arch/powerpc/boot/treeboot-walnut.o] Error 1
make: *** [uImage] Error 2

This is using ELDK 4.1:
GNU assembler version 2.16.1 (powerpc-linux) using BFD version 2.16.1
gcc version 4.0.0 (DENX ELDK 4.1 4.0.0)

Cheers,

Fixed in my tree.  I'll ask Paul to pull soon.

Looks like the problem is back:

   BOOTCC  arch/powerpc/boot/treeboot-walnut.o
Assembler messages:

Internal error, aborting at 
/tmp/crosstool/crosstool-0.42/build/powerpc-unknown-linux-gnu/gcc-4.0.2_e300-enabled-glibc-2.3.6/binutils-2.16.1-complete/gas/config/tc-ppc.c

Please report this bug.

Question: I'm building a kernel for the 8610.  Why is treeboot-walnut.c being 
compiled at all?

I thought that got fixed already, did the CFLAGS override fall out
somehow?

Policy.  Compiling everything means build bugs - like this one - can
be found by everybody, not just those building for the specific
obscure platform.

Is this a new policy?  Modules in the kernel are not built unless you want 
them.  Even in arch/powerpc/platforms, only the specific platform file I'm 
targeting is built.  So I don't really understand why you claim it's normal 
for platform-specific files to be built, regardless of the actual platform.

And frankly, I don't like this "policy".  Build bugs for 4xx should not 
interfere in my 83xx development.  I can't build any kernels now because of 
this bug!

I fixed this bug.  It should be in Paul's latest tree.  You seem to be
having a different issue with your binutils though.

Just to clarify this is an issue with the particular patched binutils  
Timur is using.

I'll leave it to you guys to fight over if we should be building  
everything or not.

It has been policy as long as we've had the platform+library structure
in arch/powerpc/boot.

The wrapper script is intended to be a standalone tool which is
independent of the kernel configuration, and can be used separately
from the kernel build process.

I'm sure you're not actually that helpless. :)  Just carry a patch to
arch/powerpc/boot/Makefile in your local tree.

Is it ever actually used that way?  I wonder if this "intent" is worth the
pain...

Of course, it also introduces bugs that wouldn't have been an issue if we
didn't try to build everything with the same toolchain. :-P

I'm also somewhat worried what it'll do to build time as platforms
accumulate.

It also provides incentive to keep the bootwrapper small...

No; this is something different.  The assember itself is failing
internally.  What version of binutils are you running?

2.61.1 if we believe his path :)

the assembler is failing because 'icbt' has several possible  
different instruction encodings and I'm guessing he's getting a  
conflict set.

What's the actual compile line?  Want to see the flags to assembler  
of -Wa to the compiler.

How do I modify the makefiles to spit out that command line?
