See http://patchwork.openembedded.org/patch/116843/ discussion, the
patch from Ross mentioned bellow fixes it better and is already merged
in master.

BTW: this is causing gdb-cross-* to depend on target readline, which may
have different signatures for different MACHINEs with the same arch.

E.g. after adding qemuarm7 MACHINE, you can easily get gdb-cross-arm
being rebuilt/extracted-from-sstate after each MACHINE change.

I'm not sure why selftest didn't catch this, but it can be seen with:

Something has regressed. Do you know when this last passed? Looks like
we need to add some extra tests to selftest and get this fixed.

Sadly I'm drowning in problems to fix at the moment :(

To answer my own question, it looks like:

gcc-configure-common.inc:EXTRA_OECONF_append_armv6 = " --with-arch=armv6"
gcc-configure-common.inc:EXTRA_OECONF_append_armv7a = " --with-arch=armv7-a"
gcc-configure-common.inc:EXTRA_OECONF_append_armv7ve = " --with-arch=armv7-a"

which effectively comes from:

http://git.yoctoproject.org/cgit.cgi/poky/commit/meta/recipes-devtools/gcc/gcc-configure-common.inc?id=c0a071e16ec04f485f06eece5b807e5afbe1c1f1

The concept of having one gcc for each arch precludes such changes :(.

I believe these overrides need to move to the gcc-target.inc file.

Reverting this change in Dizzy based build fixes the signatures for
gcc-cross(-initial)-arm

for gdb-cross-arm, there is still datadir -> TUNE_PKGARCH dependency from even
older change:

OE qemuarm7@ ~/build/oe-core/openembedded-core $ git show -1 3e87aba1
commit 3e87aba1ee2ca0e39ba66fb7cba52e48df499c23
Author: Phil Blundell <pb@pbcl.net>
Date:   Wed Apr 24 16:15:54 2013 +0100

    gdb-cross: Adjust ${datadir} to avoid file conflicts in sysroot
    

+datadir .= "/gdb-${TUNE_PKGARCH}${TARGET_VENDOR}-${TARGET_OS}"

Reverting this change fixes gdb-cross-arm signatures.

Will try what happens when I revert this in master and move --with-arch
options to gcc-target.inc only.

I have an untested patch for the latter:

http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=rpurdie/wip
&id=3b30d958abff7ab913ed9d4852dfd44a57e84eb1

(just not gotten to it yet).

We do have a bigger problem in that I think if you switch tunes between
things which change TARGET_OS (e.g. an x86 x32 build, mips n32 or ppc
spe) we'll have the same issue. To fix that we'll likely need the
target OS mangling that cross-canadian does and that is going to be
pretty invasive to implement.

The good news is that sstate will remove/install the correct gcc-cross
quite happily so whilst annoying, builds don't break.

The ppc spe v1 issue is more pressing since python3 is breaking on the
autobuilder due to that :(

Cheers,

Richard

Yes.  Fundamentally the Yocto concept of arch appears to be inconsistent 
with gcc's concept in that the defaults for Yocto don't match the 
defaults for gcc on the same platform.  At the time I submitted that 
patch reworking how the toolchain is built wasn't feasible.

I'm not working with Yocto at this time so can't contribute to the 
solution, however if/when I get the opportunity I can help verify that 
the bug the patch fixed hasn't been re-introduced.
