[Buildroot] [PATCH 0/9] Fix internal blackfin toolchain

[Gustavo Zacarias]

This patchset fixes the internal blackfin toolchain build.
It's been broken for ages (never worked maybe?)
Testers wanted, it builds what's supposed to build but i lack hardware
to see if it really works.

Gustavo Zacarias (9):
  gcc/bfin: doesn't support --with-cpu defaults
  uclibc/bfin: only supports linuxthreads.old
  uclibc: make target utils optional
  gcc/bfin: 4.{6,7,8}.x are broken
  uclibc: use builtin startfiles target
  uclibc/bfin: set the appropiate binfmt in the configuration
  uclibc/bfin: don't install host utils if not FDPIC
  blackfin: set GNU_TARGET_NAME accordingly
  gcc/mudflap: disable for blackfin, it doesn't build

This looks odd because the BR2_GCC_TARGET_CPU_REVISION thing was added
by Sonic Zhang, see 66d41890ec2b76189bcd427a0cc3966ff56f9712. So it is
specifically useful on Blackfin. Maybe just with Analog Devices
toolchains, I don't know. But clearly, removing that for Blackfin seems
wrong.

Exactly, with their twisted toolchains, snip without it:

checking for clock_t... yes
checking for .preinit_array/.init_array/.fini_array support... yes
checking if mkdir takes one argument... no
This target does not support --with-cpu.
Valid --with options are:
make[1]: *** [configure-gcc] Error 1
make[1]: Leaving directory
`/home/gustavoz/b/fin/output/build/host-gcc-initial-4.5.4/build'
make: ***

While at re-ordering, you could have also reorderd x86_i386.
Note this in the commit log, such as:
   trivial options re-rodering at the same time.

Although I would prefer you not mix cosmetics with actual changes.

Regards,
Yann E. MORIN.

As suggested by Yann, I've splitted this in two patches, one adding
the !bfin dependency, another one doing the re-ordering, including
x86_i386.

Now that we've dropped 0.9.31.x we can use the startfiles /

Isn't the 'uclinux' OS part something that is not specific to Blackfin?
I.e, should this rather be something like:

ifeq ($(BR2_USE_MMU),y)
OS=linux
else
OS=uclinux
endif

GNU_TARGET_NAME=$(ARCH)-buildroot-$(OS)-$(LIBC)$(ABI)

Thanks!

[Buildroot] [PATCH 8/9] blackfin: set GNU_TARGET_NAME accordingly

In theory, yes.
For blackfin, doesn't seem so.
Seems (caveat: no access to blackfin.uclinux.org IF it's even
documented, bizarre patches and so on) that for blackfin being MMU-less
across the whole arch it's used to select from FDPIC and FLAT*.
Again going to the source (gcc to be precise) we see that crtreloc.o
(for FDPIC targets) is used in gcc/config/bfin/linux.h (linux tuple),
and crtlibid (for FLAT targets, internal to gcc) is used in
gcc/config/bfin/uclinux.h
crtreloc.o is generated by uClibc only when doing FDPIC, and used by
'linux', and 'uclinux' doesn't do FDPIC (no linking with crtreloc.o)
hence FLAT.
Regards.

I've changed that to keep a single GNU_TARGET_NAME definition and to
use a new TARGET_OS variable, like the existing LIBC and ABI variables
we had.

Committed entire series, with the minor fixes I pointed on the
individual patches.

Note that when you select FLAT format, it is still ELF binaries that
are produced in $(O)/target. Most likely related to our non-working
handling of elf2flt, as discussed recently on the list regarding ARM
noMMU platforms. So this patch series certainly improves the situation,
but doesn't fix the whole thing yet :)

Thanks!

Thanks.
Yes, as i've stated, it's a first patchset/try of fixing things, but
most certainly not tested :)
I've been playing a bit with fixing ARM nommu, quick notes say we need
to ditch libmudflap, change the tuple (uclinux-eabi & maybe
uclinux-elf), make host-elf2flt a hard dep (it's invoked at link time by
gcc with the appropiate tuple), probably add the mmu-less cortex
processors (M*, R4), and get someone to test the whole thing.
I've still didn't get the whole thing to build properly but it's close.
Regards.
