[Buildroot] [pull request v2] Pull request for branch for-2012.02/ext-toolchain-updates

[Thomas Petazzoni]

Hello,

What follows is a set of patches doing various improvements and
updates to the external toolchain support:

 * Fixes to the x86_64 handling of BR2_GCC_TARGET_ARCH and addition of
   the Atom processor variant. Those changes are needed to make a
   better usage of the Sourcery CodeBench x86/x86_64 toolchain (i.e,
   allow the selection of the available multilib variants).

 * Improve the logic to copy libraries from the toolchain to the
   staging directory and the target directory to handle the directory
   organization of the Sourcery CodeBench x86/x86_64 toolchain.

 * Improve the same logic to support multilib toolchains with multilib
   variants in directories of multiple levels. For example, the MIPS
   Sourcery CodeBench toolchain has many multilib variants, and some
   of them are in directories like mips16/soft-float/el/. This
   requires a small modification of the way we create the symlink that
   allows to fake the original sysroot location.

 * Expand the external toolchain wrapper to include
   BR2_TARGET_OPTIMIZATION.

 * Various updates to the available external toolchains: add ARM
   Sourcery CodeBench 2011.03, update the MIPS Sourcery CodeBench
   2011.03, add the PowerPC Sourcery CodeBench 2011.03, add the
   x86/x86_64 Sourcery CodeBench 2011.09, add the Blackfin 2011R1-RC4
   toolchain.

 * Document how to use the various multilib variants available.

 * Adjust the uClibc detection logic to support static-only
   toolchains.

 * Adds support for the Linaro 2012.01 toolchain.

Changes since the v1 posted on January 4th 2012:

 - Add comments mentionning that Atom processors are only supported
   since gcc 4.5 (Peter Korsgaard comment)

 - Re-add $(Q) where appropriate (Thomas De Schampheleire comment)

 - Replaced CodeSourcery by Mentor Graphics where appropriate (Thomas
   De Schampheleire comment)

 - Add support for the Linaro 2012.01 toolchain

This patchset has been tested by doing a Buildroot build of a simple
Busybox filesystem, with the following toolchains used as external
toolchains:

 * ARM CodeSourcery 2010q1, default multilib config (ARMv5)
 * ARM CodeSourcery 2011.03, ARMv4 multilib config
 * ARM CodeSourcery 2011.03, default multilib config (ARMv5)
 * ARM CodeSourcery 2011.09, Thumb2 multilib config
 * ARM CodeSourcery 2011.09, default multilib config (ARMv5)
 * Blackfin toolchain, with shared lib support
 * Blackfin toolchain, without shared lib support
 * Basic ARM Buildroot external toolchain with C++ support

[Buildroot] [PATCH 01/16] Add x86_64 variants to BR2_GCC_TARGET_ARCH

[Thomas Petazzoni]

With the Sourcery CodeBench IA32/AMD64 toolchain, the proper -march=
switch must be passed. So, on x86_64, we make sure that
BR2_GCC_TARGET_ARCH gets defined to the correct value, just as we do
on x86.

[Buildroot] [PATCH 03/16] Improve external toolchain logic to support IA32 Sourcery CodeBench toolchain

[Thomas Petazzoni]

The IA32 Sourcery CodeBench toolchain has a relatively special
structure, with the following multilib variants:

 * Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to
   the main sysroot, with the libraries in the lib/ directory.

 * Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative
   to the main sysroot, with the libraries in the lib64/ directory.

 * Intel Atom 32 bits, the multilib variant is in atom/ relative to
   the main sysroot, with the libraries in the lib/ directory.

 * Intel Core 2 64 bits, the multilib variant is in core2/ relative to
   the main sysroot, with the libraries in lib64/ directory.

So the first two variants are in the same sysroot, only the name of
the directory for the libraries is different.

Therefore, we introduce a new ARCH_LIB_DIR variable, which contains
either 'lib' or 'lib64'. This variable is defined according to the
location of the libc.a file for the selected multilib variant, and is
then used when copying the libraries to the target and to the staging
directory.

In addition to this, we no longer use the -print-multi-directory to
get the ARCH_SUBDIR, since in the case of the 64 bits variants of this
toolchain, it returns just '64' and not a real path. Instead, we
simply compute the difference between the arch-specific sysroot and
the main sysroot.

We also take that opportunity to expand the documentation on the
meaning of the different variables.

[Buildroot] [PATCH 04/16] Support multilib variants in sub-subdirectories

[Thomas Petazzoni]

When an external toolchain has multiple variants organized in
sub-directories, Buildroot only copies the selected sysroot and not
all sysroots. In order to make this work, Buildroot creates a symbolic
link of the name of the original selected sysroot to the main sysroot
to trick the compiler so that it finds its libraries at the expected
location.

I.e, if the toolchain as the following organization (example take on
the ARM CodeSourcery toolchain) :

     .	    	for ARMv5T
     armv4  	for ARMv4T
     thumb2 	for ARMv7-A/Thumb

and ARMv4T is selected, then Buildroot will copy the contents of
armv4t/ from the toolchain into its $(STAGING_DIR) and then create a
$(STAGING_DIR)/armv4t symbolic link to $(STAGING_DIR).

However, our logic to do so only works when there was one directory
level for multilib sysroots. But in the MIPS CodeSourcery toolchain
there are multiple levels. For example, the MIPS16 soft-float
little-endian sysroot variant is in mips16/soft-float/el/ compared to
the main sysroot.

This patch improves our logic to support this case. The logic is a bit
more complicated as we don't want to create a symbolic link to an
absolute path, but a symbolic link to a relative path, because we want
the host/ directory to be relocatable.

[Buildroot] [PATCH 05/16] Expand external toolchain wrapper to custom flags

[Thomas Petazzoni]

The BR2_TARGET_OPTIMIZATION flags were not used by the external
toolchain wrapper, which broke the multilib selection logic of
multilib external toolchains. It also simplifies the compilation of
external programs since all flags are properly passed automatically by
the toolchain wrapper.

I still have an issue with CodeSourcery toolchain and u-boot for TI (am3517):

CodeSourcery toolchains from 2009 produce correct code, but two latest
produce wrong code (u-boot is functioning, but cannot start kernel). I
reported on this issue for some time and last week I worked with
u-boot again and tested various toolchains. Peter, you said you're
going to work with TI hardware, could you please check this issue?

I don't normally use codesourcery toolchains, but will give it a try
once I have hw.

That's good to know, but I don't think it should prevent the newest
CodeSourcery toolchains from being integrated into Buildroot: there are
many other targets for which they generate correct code. Or maybe I
missed your point?

I'm not against new versions. I just like to understand and fix the
issue. Perhaps I should ask this question in the u-boot mailing list.

[Buildroot] [PATCH 12/16] external-toolchain: details on selecting the multilib variants

[Thomas Petazzoni]

Each multilib variant need to be selected using a special combination
of flags, requiring specific choices of the Buildroot options. This
commit documents those configuration choices to make it easier to use
the various multilib variants.

[Buildroot] [PATCH 13/16] external-toolchain: run checks even on extracted toolchains

[Thomas Petazzoni]

When the mechanism that allows Buildroot to download external
toolchains automatically was added, all the sanity checks on the
external toolchains were not performed. This commit re-enables those
checks that we already do on external toolchains that are not
downloaded/extracted by Buildroot. This makes the toolchain checks
more consistent accross various configurations.

[Buildroot] [PATCH 14/16] external-toolchain: adjust check for uClibc static toolchains

[Thomas Petazzoni]

The current check for uClibc toolchain was verifying that a
ld-uClibc.so dynamic loader was present. However, with static-only
uClibc toolchains, this does not work. Instead, we check for an
uClibc-specific header file in the sysroot.

[Buildroot] [PATCH 16/16] external-toolchain: add support for Linaro 2012.01

[Thomas Petazzoni]

Linaro has just released a new pre-built toolchain, available as a
tarball, which is a pure toolchain (only the C library is
included). This makes this new Linaro 2012.01 toolchain usable in
Buildroot, so let's integrate the support for it.

In addition to simply adding the new external toolchain at the usual
locations, this patch allows need to adapt a few things to support
Linaro toolchains. Most toolchains store their libraries in the "lib/"
or "usr/lib" directories relative to the toolchain. Buildroot
toolchains on the other hand, store the libraries in the
"usr/<target-name>/lib" directory. And the Linaro toolchain has
choosen to use the "lib/<target-name>" directory. Therefore, this
patch adjust:

 * The logic to search a particular library when that library needs to
   be copied to the target directory

 * The logic to deduce the sysroot directory from the libc.a file
   location in the toolchain: removing "(usr/?)lib(64?)" is no longer
   sufficient, we need to take into account the "lib/<target-name>/"
   case.

Since the Linaro toolchain generates code for Cortex-A processors
only, the selection of this toolchain is limited to Cortex-A8 and
Cortex-A9.

 Up to patch 14/16:
Tested-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
 on i386 and x86_64 with a random set of packages.

>       external-toolchain: fix description of PowerPC 2010.09 from Mentor Graphics
>       external-toolchain: add support for Linaro 2012.01
 But those two shouldn't affect x86 architectures.

 Regards,
 Arnout

[Buildroot] [pull request] Pull request for branch for-2012.05/ext-toolchain-updates

[Thomas Petazzoni]

Hello,

What follows is a set of patches doing various improvements and
updates to the external toolchain support:

 * Fixes to the x86_64 handling of BR2_GCC_TARGET_ARCH and addition of
   the Atom processor variant. Those changes are needed to make a
   better usage of the Sourcery CodeBench x86/x86_64 toolchain (i.e,
   allow the selection of the available multilib variants).

 * Improve the logic to copy libraries from the toolchain to the
   staging directory and the target directory to handle the directory
   organization of the Sourcery CodeBench x86/x86_64 toolchain.

 * Improve the same logic to support multilib toolchains with multilib
   variants in directories of multiple levels. For example, the MIPS
   Sourcery CodeBench toolchain has many multilib variants, and some
   of them are in directories like mips16/soft-float/el/. This
   requires a small modification of the way we create the symlink that
   allows to fake the original sysroot location.

 * Expand the external toolchain wrapper to include
   BR2_TARGET_OPTIMIZATION.

 * Various updates to the available external toolchains: add ARM
   Sourcery CodeBench 2011.03, update the MIPS Sourcery CodeBench
   2011.03, add the PowerPC Sourcery CodeBench 2011.03, add the
   x86/x86_64 Sourcery CodeBench 2011.09, add the Blackfin 2011R1-RC4
   toolchain.

 * Document how to use the various multilib variants available.

 * Adjust the uClibc detection logic to support static-only
   toolchains.

 * Adds support for the Linaro 2012.01 toolchain.

Chances since the v2 posted on January 28th 2012:

 - Update to latest master.

Changes since the v1 posted on January 4th 2012:

 - Add comments mentionning that Atom processors are only supported
   since gcc 4.5 (Peter Korsgaard comment)

 - Re-add $(Q) where appropriate (Thomas De Schampheleire comment)

 - Replaced CodeSourcery by Mentor Graphics where appropriate (Thomas
   De Schampheleire comment)

 - Add support for the Linaro 2012.01 toolchain

This patchset has been tested by doing a Buildroot build of a simple
Busybox filesystem, with the following toolchains used as external
toolchains:

 * ARM CodeSourcery 2010q1, default multilib config (ARMv5)
 * ARM CodeSourcery 2011.03, ARMv4 multilib config
 * ARM CodeSourcery 2011.03, default multilib config (ARMv5)
 * ARM CodeSourcery 2011.09, Thumb2 multilib config
 * ARM CodeSourcery 2011.09, default multilib config (ARMv5)
 * Blackfin toolchain, with shared lib support
 * Blackfin toolchain, without shared lib support
 * Basic ARM Buildroot external toolchain with C++ support
 * Basic ARM Buildroot external toolchain without C++ support
 * ARM Buildroot toolchain with all features enabled (largefile, etc.)
 * ARM Buildroot toolchain without thread support
 * Crosstool-NG ARM eglibc toolchain
 * Crosstool-NG ARM uClibc toolchain
 * Crosstool-NG mipsel eglibc toolchain
 * x86 Buildroot toolchain with all features enabled
 * mipsel o32 Buildroot toolchain with all features enabled
 * PowerPC e500mc Buildroot toolchain with all features enabled
 * x86_64 Nocona Buildroot toolchain with all features enabled
 * Crosstool-NG mips uclibc toolchain
 * Crosstool-NG powerpc uclibc toolchain
 * Crosstool-NG x86_64 eglibc toolchain
 * CodeSourcery PowerPC 2010.09, 603 multilib variant
 * CodeSourcery PowerPC 2010.09, e500mc multilib variant
 * CodeSourcery PowerPC 2011.03, e500v2 variant
 * CodeSourcery PowerPC 2011.03, default multilib variant
 * CodeSourcery PowerPC 4.4, default multilib variant
 * CodeSourcery IA32 2010.09 x86_64 Core 2 toolchain
 * CodeSourcery IA32 2010.09 x86 Pentium 4 toolchain
 * Linaro ARM 2012.01 toolchain
 * CodeSourcery MIPS 2011.03, default multilib variant

[Buildroot] [PATCH 06/16] external-toolchain: remove 2009q1 ARM Sourcery toolchain

[Thomas Petazzoni]

We are going to add one more ARM Sourcery toolchain version, so it's
time to remove the oldest version.
