[Consult] About tool chains of metag

[Chen Gang]

Hello James Hogan:

Could you provide any related information about metag tool chains?

I plan to cross compile metag with allmodconfig, but now it seems not
quite easy to find related gcc (binutils-2.23.2 support metag, but gcc
main line does not).

And also, welcome any related suggestions or completions.

:-)

Thanks.

A buildroot tree containing a gcc-4.2.4 patch can be found here:

git://github.com/img-meta/metag-buildroot.git metag-core

Use meta2_defconfig

There's a known issue with all/random config builds with this toolchain
which results in internal compiler errors triggered by the inline asm in
arch/metag/include/asm/io.h when used by certain drivers, so I need to
update the patch to the latest before these will go away.

The other main issue with all/random config builds for Meta is a few
missing !METAG dependencies on legacy PC peripherals like SERIO_I8042,
which I believe you've already come across for Arc.

Please read this thread before attempting to fix them:
https://lkml.kernel.org/r/201211161520.03974.arnd-r2nGTMty4D4@public.gmane.org

I haven't got around to fixing this properly myself, but it would be a
worthwhile improvement if you felt inclined to do so.

Cheers
James

I've pushed a new buildroot branch which has the updated GCC 4.2.4 patch:

git://github.com/img-meta/metag-buildroot.git metag-core-2013.11
Again use meta2_defconfig.

Tony: Is this something you can easily use to generate a Meta toolchain
for https://www.kernel.org/pub/tools/crosstool/?

Thanks
James

Re: [Consult] About tool chains of metag

[Chen Gang]

Thank you very much for your details valuable information.

I will/should try my best to let it pass allmodconfig, and I guess
https://lkml.kernel.org/r/201211161520.03974.arnd-r2nGTMty4D4@public.gmane.org is valuable
to me, and I will/should reference it.

I will/should try to finish allmodconfig within one month, but excuse
me, I have to do it in my free time as a volunteer, so maybe it needs
longer (but at least, it should be finished within 2014-1-31).

Thanks.

Oh, excuse me, I can not access "https://lkml.kernel.org/r/..." in
normal way in China.  :-(

Could you please provide another links which include the same contents?

That is really valuable to me!!

You and arnd have done much for HAVE_XXX, and I should continue to try
based on your work. For me, it is really a suitable solution for all
HAVE_XXX (although still need think of more details).  :-)

Welcome another related members to provide your suggestions or completions.

Re: [Consult] About tool chains of metag

[Chen Gang]

Hello Maintainers:

After tried, I guess related binutils and gcc are not match with each
other: gcc support "-minim" option which will pass to gas, but gas can
not recognize it.

With "-mno-minim" option, we can try to bypass this issue (I am just
trying), but it seems not a quite good idea.

Welcome any additional suggestions or completions for it, thanks.

Did you use meta2_defconfig in buildroot as I suggested?

It has --enable-meta-default in BR2_EXTRA_GCC_CONFIG_OPTIONS which prevents 
the compiler defaulting to minim (which isn't supported for Linux).

Oh, sorry, I didn't, I missed understanding (originally, I only noticed
meta2_defconfig for Linux kernel, didn't notice another meta2_defconfig
for global).

Next, I will/should try.

Thank you very much for your details information (after that, we can
generate cross compiler).

And I will/should use "--enable-meta-default" and another options to
generate individual cross-compiler and continue to compile kernel with
allmodconfig.


:-)
