Hi all,

Accidentally the first patch of the series was missing in v3 (wrong usage
of git format-patch command on my side...). So this is a resend of v3, but
now with an extra patch!

The patch set is also published on our github site: 
https://github.com/foss-for-synopsys-dwc-arc-processors/buildroot

Thanks, Mischa

Changes in v4:
 * re-added missing bison/flex host dependencies patch for gcc

Changes in v3:
 * removed GCC arch-dependency cleanup patch (should be discussed separately)
 * 3.9-rc8-->3.9 kernel headers
 * Added bison/flex host dependencies

Changes in v2:
 * BR2_ARC_SITE hardcoded now, and moved to Config.in.arc
 * makeinfo dependency removed from binutils
 * Added 3.9-rc8 kernel headers
 * Patches split where suggested
 * Removed ARC-specific uClibc config
 * Moved ARC-specific binutils out of the choice menu
 * Introduced explicit BR2_arcel, BR2_arceb symbols a la microblaze
 * Added a patch that cleans up GCC architecture dependencies
 * Fixed patches for binutils, gcc

Mischa Jonker (12):
  toolchain/gcc: Add host-{flex,bison} dependencies for GCC 4.2,4.3,4.4
  arc: Add ARC and ARC BE architecture
  arc: Add option for ARC-specific download site
  arc: Add support for ARC-specific binutils
  arc: disable Crosstool-NG for ARC
  arc: add gcc for ARC
  arc: Add support for ARC-specific uClibc
  arc: Make sure that libgcc doesn't get included when it doesn't exist
    yet
  toolchain/gcc: Only enable --with-float when it makes sense
  toolchain/toolchain-buildroot: Disable NPTL for ARC
  arc: Add arc, arcbe to gnuconfig
  kernel-headers: Add support for ARC kernel headers

Note that gcc doesn't use the package infrastructure, and needs proper
$(HOST_MAKE_ENV) and $(TARGET_MAKE_ENV) to be able to find host-flex/
host-bison.

Original patch by Thomas Petazzoni.

As ARC support is not yet in all upstream packages, a different location is
required to download the packages from. This adds an option to specify a
site for ARC-specific versions of packages such as binutils, gcc.

When ARC support has been upstreamed for all packages, this option can be
removed again.

ARC needs a specific GCC for now, while we wait for ARC support to get
upstreamed.

+arc: Fix operand-out-of-range errors

+brcc_s instructions can generate operand-out-of-range errors. While a
+better solution is being discussed by the compiler team, this workaround

For ARC, libgcc is always included, even when -nostdlib is given. This is
related to some small pieces of code that are not always generated by the
compiler; a call to libgcc is used in those cases instead.

During the initial stages of building the toolchain, this is a problem, as
libgcc does not exist yet. The ARC compiler supports -really-nostdlib to
override the default behavior.

According to gcc/config.gcc, only ARM, MIPS and SPARC have the
"--with-float" option when configuring gcc.

This all looks good to me. Peter, can you pull/apply the 12 patches from
Mischa so that we get this in -rc1 ?

Thanks,

Ehh, two things:

- This implements the opposite logic of what the commit message says
  (E.G. adds flex/bison if the version ISN'T 4.2/4.3/4.4)

- It overrides GCC_HOST_PREREQ instead of appending to it even though
  the line just above already appends something.

It isn't clear to me what the gcc version logic should be, and if it is
somehow related to ARC - I don't recall any autobuilder failures
regarding missing flex/bison.

Dear Peter Korsgaard,

Hum, right. Mischa, could you fix those and submit a patch? I've added
a ARC configuration to the autobuilders, and it is now failing since
Peter didn't commit this patch.

The problem is that those old gcc versions require flex/bison to build
properly. The issue was not seen on the autobuilders, because so far the
only architectures that are using those old versions are AVR32 (4.2)
and SPARC/Leon (4.4).

For AVR32, the autobuilder uses a an external toolchain which was built
with a previous version of Buildroot, at a time where the autobuilder
chroot had bison and flex installed system-wide.

For SPARC, there is no autobuilder configuration (maybe I should add
one?).

So this bug already exists today, independently of the ARC support: I
think that if you try to build the AVR32 internal toolchain on a system
where bison and flex are not installed, the build is going to fail.

See
http://autobuild.buildroot.org/results/cc6c6f8036ee2a35c3eec36cf3f4338e76c19d68/build-end.log
for an autobuilder failure that exhibits the problem.

Best regards,

Thomas
