test-suite: Added new test suite feature (experimental)

This patch adds support for installing the gcc test suite. A helper
Makefile is provided for building and running the gcc tests.

The default configuration runs all gcc tests and requires automatic
ssh/scp login access to a networked target board. See README for
more details.

Note: Current feature is tested with the powerpc-unknown-linux-gnu
sample but it should work with others as well.

scripts/wrapper.c: Under MacOS set DYLD_LIBRARY_PATH

Depending on (predefined) macro __APPLE__, use DYLD_LIBRARY_PATH
instead of LD_LIBRARY_PATH.

docs/overview.txt: Provide short mercurial HOWTO

The usage of hg mq is imho not very well documented.
Give a short intro for the most important use cases
for contributions to ct-ng.

yann.morin.1998@anciens.enib.fr:
Slightly rewrote the explanations for the introductory message.

ct-ng: Add ability to configure and use some GNU tools

Make the paths to libtool, objcopy, objdump, readelf, patch configurable.

scripts/build/internals.sh: Always use binary wrapper under BSD/MacOS

The shell wrapper script uses a nonportable call to readlink.
Thus, always use the binary wrapper under BSD/MacOS.

yann.morin.1998@anciens.enib.fr:
Use 'case' instead of 'if'.

scripts/wrapper.in: Add a comment about readlink not being portable.

Documented that the call to readlink will not work on BSD systems.

configure: make call to readlink portable to non-GNU (BSD) systems

The argument '-e' for readlink is a GNU extension.
In setting the variable 'where' the argument '-e' is not necessary, thus eliminated.

scripts/crosstool-NG.sh.in: On MacOS/BSD use the output of CT_DoConfigGuess for CT_BUILD.

On 64bit MacOS `gcc -dumpmachine` gives i686 for the host machine.
This conflicts with the expectations of some following configure scripts
that a 64bit x86 is given as x86_64; i686 is understood as a 32 bit machine.
config.guess sets the host machine in CT_BUILD correctly.

yann.morin.1998@anciens.enib.fr:
As suggested by Khem RAJ on the ML, always use config.guess.

configure: Do not require stat to be of GNU coreutils

calls to stat have been made portable, thus it is not necessary
that the GNU version is present on the user's system.

scripts/functions: Use stat correctly on non-GNU (BSD/Darwin) systems.

Call to get the directory mode depending on $CT_SYS_OS

yann.morin.1998@anciens.enib.fr:
CT_SYS_OS has changed on Linuxsystem, it only gets the kernel name "Linux",
and not the system name, 'GNU/'.

build/internals.sh: Replace nonportable call to stat

The call to stat to find out if a file is a symlink works only on GNU systems,
and the replacing portable call to readlink is also shorter and more concise code.

yann.morin.1998@anciens.enib.fr:
Apply simpler test, after discussion with author and Arnaud LACOMBE on the ML.

crosstool-NG.sh: suppress failure message from uname -o

On non-GNU systems (BSD/MacOS) there is no uname -o.
Suppress the failure message on these systems in the
call to set CT_SYS_OS (uname -s actually sets this variable).

yann.morin.1998@anciens.enib.fr: remove 'uname -o' altogether.

When cpmpanion libraries are built statically, it is useless to set

non-shared companion libraries. Document that.

cc/gcc: use proper host compiler for canadian bare-metal

While compiling a canadian toolchain for host=mingw32, build=linux,
target=m68k-elf the build fails because in this step of the gcc build
the Host compiler is used in this stage with the build-flags for the
build system. This results in an error where the header <sys/wait.h>

Insight seems to be very slow to follow up on mainstreram gdb.
Latest snapshots are more than 6 months old.

Moreover, I don't have time to maintain insight support in crosstool-NG;
and, because I don't use it, I am unable to find any breakage.

debug/gdb: reorder options in the menuconfig

complibs/gmp: mark 5.0.1 as being experimental

MPFR can't cope with GMP > 4.x.y so hide it behind EXPERIMENTAL

samples: add Blackfin sample

Add basic support for the Blackfin architecture

For uClibc, the name of the Blackfin architecture is 'bfin'. Actually,
the naming of the architecture is quite messy: for toolchain tuples
and uClibc, it's bfin, but for the kernel, it's blackfin. We've
arbitraly choosen to name it "blackfin" in Crosstool-NG.

Add Blackfin-related uClibc patch to fix a build failure related to
fork() being used in unistd/daemon.c.

Yann E. MORIN:

config: fix style issues when source-ing files

Always enclose the sourced file between double-quotes (purely for
consistency; enclosing or not are both allowed by the kconfig language).

config: move backend-related options to their own file

config: hide arch and kernel selection when used as a backend

When used as a backend, it is the responsibility of the upper-layer build
system to set the target architecture and kernel.

config: hide options to debug crosstool-NG when a backend

When used as a backend, it does not make sense to debug crosstool-NG,
so hide the option.

config: hide more config options when a backend

Hide the prompts for some behavioral options, for which the upper-layer build
system is responsible for:
- parallel jobs and maximum load
- use pipes
- use custom shell

config: hide paths when used as a backend

When crosstool-NG is used as a backend, it is the responsibility of the
upper-layer build-system to properly set paths, so we just hide the
prompts in this case.

scripts/populate: optimise search loop

Curently, populate will iterate over all ELF (shared objects|executables)
to look for missing NEEDED DSOs, adding to the list at every iterations
of the search loop.

Instead of looking again at previously handled ELF files, recursively
resolve every ELf files.

Also, in case there are a whole lot of files (more than the shell can
accept as arguments list, or creating a command line longer than the
shell can cope with), use a temporary file with the list of files
to search for missing dependencies.

scripts/populate: cleanups and misc fixes

- it's a POSIX compliant shell script: drop bash, use /bin/sh
- fix help text
- use an absolute path for sysroot
- replace "echo" with "printf"
- replace "stat -c '%i'" with "ls -1id"
- replace "pushd / popd" with "cd / cd -"
- remove superfluous break
- bail out if required lib not found, except if forced

scripts/populate: fix handling the forced libraries list-file

If a list-file is used, then each library in the file will be handled
twice (not a real issue, as the second iteration will find the library
already present, just avoid doing the job twice).

scripts/populate: properly locate the sysroot and required tools

This fixes two problems:
- the sysroot might be in a sub-directory (think SYSROOT_DIR_PREFIX)
- it is not needed to have the target tuple to properly detect the sysroot
and the required tools

As a side effect, this script is now no longer dependent on the target
tuple, and in the future, we might be able to share it across many
toolchains (when/if we can install all of them in the same place).

scripts/populate: add -m option, to merge source and dest

Merge the source rootfs into the (pre-existing) destination rootfs,
and populate the result accordingly.

scripts/populate: add option to use an alternate sysroot

Add a new command line option, "-r", which allows the user to specify
an alternate sysroot location to copy libraries from. This is useful
when using the toolchain in combination with a separate root filesystem,
or when working with multiple different root filesystems.

When using an environment variable to set a config entry,

config: prepare for build-system backend

When acting as a backend for a build-system, we should not build
any application that runs on the target, that is:
- no native gdb
- no companion libraries
- no binutils libraries
- no debug tools (save for gdbserver)
- ...

Here, we simply prepare the (hidden) config option that will detect
that we are acting as a back-end.

Update doc accordingly.

libc/glibc: get the version string from version.h

We can not rely on the user-provided version string (be it via the

configure: do not require hg when configuring in an hg clone

When configuring in an hg clone, we need hg to compute the version string.
It can happen that users do not have Mercurial (eg. if they got a snapshot
rather that they did a full clone). In this case, we can still run, of
course, so simply fill the version string with a sufficiently explicit
value, that does not require hg. The date is a good candidate.

debug/strace: fix strace 4.5.19 to properly build with latest Linux kernels

Here's a couple of patches to get strace 4.5.19 to configure and build

enough while we wait for 4.5.20 to be released.

With the current strace-4.5.19 patches I failed to get the configure
script running even on my host environment. Also, when cross building
the configure script needs to look for the proper system headers to be
able to properly set HAVE_LINUX_NETLINK_H. Otherwise you get:

aria2 is a powerfull downloader that is capable of chunking and

Due to li;itations in crosstool-NG retrieval facilities, it's not possible
to take fully advantage of aria2. It might happen that, in the future,
those limitations get lifted away, so we can take use features such as
parallel downloading from more than one server at the same time. For now,
it should still speed up downloads thanks to parallel downloading of chunks.

with the new ones. This can be annoying to loose the original patches.
Fix this by putting the new patchs in a directory of their own.

patches/binutils/2.20: make patches appliable

Fix filenames in patch files for binutils-2.20.
Some patch files were only usable with patch argument '-p0'.
Fix the diff context to match 2.20 release.

samples: update all samples to the new set of options

No version change is made.

config: mark now old versions as being OBSOLETE

These versions are kept for the upcoming release, but they
will be removed from the next release if they are not used.

config/binutils: add latest version 2.20

Also add patchset vampirised from Gentoo.

debug/strace: add latest version, unmarkprevious EXPERIMENTAL

Also propagate the patchset from 4.5.18 to 4.5.19.

debug/gdb: add latest version 7.0

cc/gcc: add latest 4.4.2 version as EXPERIMENTAL

kernel/linux: add latest versions

binutils: remove duplicate config entries for binutils & elf2flt

scripts: add sed expression to apply when renumbering patches

Some patchsets have superfluous members in their names (eg. the ones coming
from Gentoo), so it can come in handy to pass a sed RE to strip them out of
the final patch name.
Also add a 'fake' mode, where the command will only be printed and not
executed, so we can check beforehand if the rename will be OK.

scripts: fis addToolVersion wrt binutils

binutils' config file has moved; update the addToolVerion script accordingly.

kernel/linux: remove the version prompt

debug/gdb: remove old versions

config/binutils: remove obsolete experimental versions

libc/uClibc: fix building on system with recent glibc

While trying to build a toolchain with ct-ng 1.5.0,
arm-unknown-linux-uclibcgnueabi target,
I get the following error:

[INFO ] Installing C library headers
[EXTRA] Copying sources to build dir
[EXTRA] Applying configuration
[EXTRA] Building headers
[EXTRA] Installing headers
[ERROR] extra/scripts/unifdef.c:209: error: conflicting types for 'getline'
[ERROR] make[2]: *** [extra/scripts/unifdef] Error 1
[ERROR] Build failed in step 'Installing C library headers'

The following patch solves the problem.
(It's a backport of this uClibc commit:
http://git.uclibc.org/uClibc/commit/?id=49e81cada73616864b9b31df0aeb6961c30f5a6e
)

[--SNIP from another mail--]
AFAIK this is a problem since glibc 2.10.

1.5: update to 1.5.0+hg

Tagging release 1.5.1

1.5: update version to 1.5.1

arch/arm: add sample for nommu bare-metal Cortex-M3 with newlib

arch/arm: add THUMB interworking support

Add config option to build wtarget code with THUMB interworking.
This is used to build the C library as well as all other code
that runs on the target.

arch/arm: add THUMB mode config option

arch/arm: no need to check for the ABI option

The ABI option can not be set if EABI was selected,
so no need to check for it.

arch/arm: add support for noMMU

Some ARM cores do not have an MMU (eg. Cortex-Mx and Cortex-Rx series).
Thus, allow the user to configure out the MMU for ARM.

libc/newlib: allow using CVS snapshots

The newlib "team" rolls new releases about once a year (december).
This is quite a long time between releases, in case code was fixed.
So, allow user to use a CVS snapshot to benefit early from fixes
and enhancements to newlib.

functions: allow using sub-dir of a module

Some projects' module (eg. newlib) are checked-out into a sudirectory
rather than into their own directory. Handle this case in the CT_GetCVS
function.

libc/newlib: allow using newlib with archs other than avr32

libc/newlib: fix namespace in config file

C library config options should be prefixed with 'LIBC_'.

libc/newlib: cleanup the build and finish steps

build step:
- ./configure
- remove glibc-specific options
- pass the target CFLAGS in the correct variable
- make:
- build in //

finish step:
- print proper message in finish step

libc/newlib: fix host/target confusion

newlib handles the build/host/target a bit differently as one would expect:
build : not used
host : the nachine that builds newlib
target : the machine on which newlib will run

debug/dmalloc: fix handling of threading model

config: add help for the MMU/noMMU entry

config/libc: move around hidden config options

This yields a cleaner .config file that is easier to read.

samples: fix the avr32-unknown-none sample

Bizarely enough, binutils-2.18 fails to build when CONFIG_SHELL is set
to /bin/bash (although it has code to recognise bash and act accordingly).

Waht is really strange is that it does build when CONFIG_SHELL is set
to /bin/sh, *although* /bin/sh is a symlink to /bin/bash. WTF?!?!

configure: split has_or_abort in two: one to check, one to abort

Split the has_or_abort function in two:
- one that checks if the tool if found,
- one that calls the above check, and aborts if not found

The rational behind this is to be able to check for a tool
and if not found, fallback to using our bundled version,
should the need arise (and I get time).

libc/glibc: don't use legacy snapshots

glibc snapshots have not been updated for about the
past 5 months. Consider them to be deprecated, now.

libc/glibc: remove dead code

The option to retrieve snapshots is already handled by
the generic 'specific date' and 'use latest' entries.
No need for a special case, as there's no code for it.

Merge.

debug/gdb: cleanup (remove) the static ncurses build

ncurses is built solely for the sake of building a native gdb.
The user should not rely on this library to build his/her userland,
but should rather build his/her own. So we remove it from the
sysroot after we successfully build the native gdb.

doc: update documentation, mostly eye-candy

sample: update the i686-nptl-linux-gnu sample

Update this sample, now it seems to correctly build again.

libc/eglibc: fix building for seemingly native toolchains

comp-libs/cloog: fix building

For CLooG/PPL 0.15.3, the directory name was simply cloog-ppl.
For any later versions, the driectory name does have the version, such as
cloog-ppl-0.15.4.

config: fix indentation for options marked EXPERIMENTAL or OBSOLETE

Change the 2-space separation into a 1-space separation, for the sake
of homogeneity.

scripts: add new version at top of choice

Add new versions at the top of the choice menu, not at the bottom.

config: re-order menu entries so that latest versions are at the top

It makes better sense to have latest versions at the top of the choice
entries.

Merge.

samples: update

comp-libs/mpc: add latest 0.7 version.

comp-libs/cloog: new versions have the version number in the dir name

For CLooG/PPL 0.15.3, the directory name was simply cloog-ppl.

cloog-ppl-0.15.4.

samples: fix saving samples

libc/eglibc: fix download

Merge.

kernel/linux: add latest versions

Add 2.6.27.33 as long-term stable, and 2.6.30.6 and 2.6.31.

gcc: add patch to fix EABI for armv4t

As pointed out by Martin GUY, gcc incorrectly generates armv5t
instrcutions for EABI, even for cores that are an armv4t.
The new patch (for the 4.3 series) fixes the problem by downgrading
the default CPU for EABI to being an armv4t core.

kconfig: allow stdin/stdout redirection

Allow stdin/stdout redirection for the CLI conf (not mconf).
This allows to recall a sample and automatically apply the defaults
to new configuration option, with something like the following:
yes "" |ct-ng "sample_name"

docs: add a tutorial on how to build a toolchain on Mac OS-X

Add a step-bystep tutorial to build a cross-toolchain on Mac OS-X.

companion libs: add latest CLooG/PPL versions

Add the latest 0.15.{4,5,6,7} CLoog/PPL.

samples: show the PPL, GLoog/ppl and MPC versions

When displaying a sample, do show the PPL, CLoog/ppl and MPC versions

samples: fix displaying selected tools

Do display selected tools / debug facilities when displaying a sample.

samples: replace usage of echo with printf

Using printf instead of echo allows easier and better formatting.

tools wrapper: fix building

Remove the build tools only after the wrapper is built.
Use the corect C compiler to build the tools wrapper.
Use the correct log level.

crosstool.sh.in: better mesage when creating script-overrides

log functions: fix CT_DoLog and CT_DoExecLog

$@ and $* are different when in double quotes; use $* to print the message.

tools wrapper: move choice selection to a more appropriate place

Move the tools wrapper choice selection down to the companion libraries
sub-menu, to avoid the user going back and forth in the menu.

tools wrapper: fix config dependency

The tools wrapper is not needed only for canadian crosses, but also
for every other type of toolchain.

docs: typo in overview.txt

TODO: update

Add TODO list for m4, autoconf, automake and libtool.
Building our own versions would remove burden from the users
who have older versions on their distributions, and are not
ready/able/allowed to upgrade.

config.{gues,sub}: update

config: move the patch choice to the extract section

Choosing the origin of the patches to apply is best
done in the 'extract' section.

config: add fallback to patch order

Add the possibility to fallback to either bundled or local patches
if local or bundled are missing.

config: add the local,bundled patch order

This ordering first applies the local patches, then the bundeld ones.

config: make selecting the patch origin a choice rather than a bool

functions: do not over-detect error when patching

Merge.

tools wrapper: fix error due to unused argument

In the C wrapper, the argc argument is not used, causing an error
(as we treat warnings as errors). Use a dummy allocation to get
rid of the warning.

tools wrapper: correctly install the C wrapper

When building the C wrapper, specify the source file to be compiled.

config: move the "build shared libraries" option to the OS menu

The "Build shared libraries" config option is dependant on the type of
"Target OS".

Moving this options to the "Target OS" sub-menu is also better in the user
perspective: he/she no longer needs to go back and forth to see if he/she
missed any option.

config: make "Build shared libraries" depend on KERNEL_SUPPORTS_SHARED_LIBS

Now that all kernels that support shared libraries select the correct config
option, we can change the dependency rules of SHARED_LIBS accordingly.

config: Linux kernel selectes shared libraries support

The Linux kernel supports using shared libraries, so prompt the user.

config: introduce the KERNEL_SUPPORTS_SHARED_LIBS silent config option

The target OSes will be able to select this option if they support shared
libraries, instead of having "Build shared libaries" depend on each OS.

config: swap the debug and tools sub-menus

ltrace, in the debug sub-menu, selects libelf, in the tools sub-menu.
Inverse the order of the two sub-menus, so that the user does not have
to go back and forth between the two sub-menus.

config: move down companion libraries sub-menu

Move the companion libraries sub-menu down the main menu.
That way, the user does not need to go back and forth in the menu
to change options set by the different components that select the
companion libraries (binutils, gcc, gdb).

companion-libs: PPL/CLooG/MPC require GMP and MPFR

The PPL, CLoog/ppl and MPC libraries require GMP and MPFR.
Select GMP/MPFR appropriately.

tools wrapper: introduce the silent WRAPPER_NEEDED config option

Add the WRAPPER_NEEDED silent config option, that can be selected by
components that require it (companion libs so far).
Rely on this config option when deciding to install the wrapper,
instead of checking GMP/MPFR or PPL/CLoog/MPC.

Merge the C wrapper.

config: choose whether to use the shell or the C wrapper

Offer a config choice on whether to isntall the script wrapper, or
the compiled C wrapper. Update docs/overview.txt accordingly.

tool wrapper: add initial wrapper coded in C

Add an initial wrapper:
- find the realpath of the tool being called
- add the '.' in front of the tool name
- add the '/lib' dir to the base dir of the tool
- set and export LD_LIBRARY_PATH
- execve the real tool

duma: fix downloading by forcing extension to .tar.gz

Downoading a non-existing file from sourceforge gives you a "200 OK"
and an index.html. As we try to retrieve a .tar.bz2 first, and duma
is bundled in a .tar.gz, we won't get appropriate content, so
just force the extension to avoid the problem.

Thanks to Ingmar Schraub <is@eseco.de> for pointing out the issue.

glibc: fix build error caused by incorrect variable assignment
