binutils/binultils: import binutils-2.20 patches from OE

This is a set of patches for binutils-2.20 that have been "ported", or rather
shamelessly stolen, from the OpenEmbedded project:

http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/binutils/binutils-2.20

Tried and tested on Arm (big-endian Xscale, and little-endian i.MX27) with GCC 4.4.2

complibs/mpfr: add latest version 2.4.2

Note: the MPFR site happens to be down at the time I wrote
this message, and happens to be down quite often.

Once it's back up'n'runnin', I'll mirror as much as possible
the MPFR tarballs on my site, but in the meantime, you'll
have to handle it by yourself (patience...).

complibs/mpc: add latest version 0.8.1

scripts/addToolsVersion: add support for MPC

cc/gcc: add patch to fix armeb in gcc-4.4

On x86, gcc-4.4.x breaks when building for target armeb.
It is still required to configure with: --disable-shared

Note: if building on an x86_64, there is no need to pass --disable-shared

scripts/addtoolversion: prepare for hooks for tools others than gcc

The upcoming git support will require hooks for glibc as well.

scripts: protect against partially extracted source

In case of failure (eg. user hitting Ctrl-C), avoid extracting over
partially extracted source. Will help once we have git available.

scripts: handle custom or empty extension when extracting

scripts/functions: do not double check if downloads are allowed

Only call the *_get functions if downloads are allowed, so there
is no need to check it again in the retrieval wrappers.

debug/ltrace: fix for a latent bug

debug/ltrace: chop long lines

debug/ltrace: set the ltrace extension to .tar.gz

Trying to download every extension in turn does not work.
The Debian server returns a friendly 404-page that is
saved as the orig.tar.bz2 file. Help the helper by giving
it the extension to retrieve.

debug/ltrace: Add support for ltrace-0.5.3

From this version of ltrace the maintainer has removed support for
GNU Autotools, so the patch sets needed to be reworked.

Included is the latest Debian patch, by the Debian ltrace maintainer
Juan Cespedes <cespedes@debian.org>, the OpenEmbedded patches for cross
compiling, by Khem Raj <raj.khem@gmail.com> and a further set of patches
by Joachim Nilsson <jocke@vmlinux.org> for crosstool-NG.

As reported by Joachim Nilsson <jocke@vmlinux.org>
in: http://sourceware.org/ml/crossgcc/2010-01/msg00005.html

It seems I need to add the 4.3.4/290-index_macro.patch to the GCC 4.4.x
series as well. I immediately trigger the following libstdc++ bug for
4.4.2 with a uClibc .config which has UCLIBC_SUSV3_LEGACY_MACROS set[1].

scripts/functions: fix downloading with aria2

In case the remote file does not exist (and probably for some
other reasons as well), aria2 nonetheless creates an empty file
(or not empty for some other reasons).

The solution is to delete the file whenever aria2 fails.

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
properly with the latest kernel headers. Not pretty, but hopefully
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:

[EXTRA] Building strace
[ERROR] /home/jocke/x-tools/targets/src/strace-4.5.19/net.c:976:
error: field 'nl' has incomplete type
[ERROR] make[2]: *** [net.o] Error 1
[ERROR] make[1]: *** [all] Error 2

The fix was simple, backport a change set from the git[1] tree and run
autoreconf to update the configure script.

debug/tools: set the ncurses extension to .tar.gz

TRying to download every extension in turn takes ages, so

scripts/functions: add aria2, a powerfull downloader

aria2 is a powerfull downloader that is capable of chunking and
parallel retrieval.

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.

scripts/functions: simplify wget vs. curl check

config: fix generated config files when GREP_OPTIONS set --color=always

grep is used when generating some .in files (in config.gen). If GREP_OPTIONS
contains --color=always, then the generated files will contains some escape
sequences setting the color, and mconf would choke on those escape sequences.

Always set and export an empty GREP_OPTIONS to avoid that.

the final patch name.
Also add a 'fake' mode, where the command will only be printed and not

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

overview: fix table of content, fix the hacker's way

table of content: add missing entry
the hacker's way: no need to "make install"

README: fix some space alignment

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.

x86_64: is a MMU-aware arch, so select ARCH_USE_MMU

duma: fix version string.

DUMA uses '_' not '.' for major/minor/sub separation.

glibc: fix build error caused by incorrect variable assignment

During the conversion to using bash arrays, the glibc build script
was improperly converted, and contains an incorrect variable
assignment to the config_options array.

Merge the bash_array branch.

For every components where it makes sense, use bash arrays (instead
of a string with space-separated values) to store the options pased
to ./configure.

Allow setting --enable-cxx-flags on gcc ./configure

Some setups require one to pass extra CXX flags at the time of ./configure.
Make it easy.

Use bash arrays to store binutils config options

Make glibc's extra_config an array containing ./configure options

Change extra_config from a string to a array of options.

Make gdb's extra_config an array containing ./configure options

Change extra_config from a string to a array of options.

Make dmalloc's extra_config an array containing ./configure options

Change extra_config from a string to a array of options.

Make gcc's extra_config an array containing ./configure options

Change extra_config from a string to a array of options.

Make eglibc's extra_config an array containing ./configure options

Change extra_config from a string to a array of options.

configure: check for bash-3.1 or above

This is required to use the array variables that came with bash-3.1.

[libc-eglibc] Rewrite part of the code

Rewrite part of the code to better match the rest.
Most notably, rewrite handling of:
if [ ... ] && [ ... ]
to:
if [ ... -a ... ]

This has the positive side effect of calling "[" only once, although
"[" is probably a shell built-in.

[libc-eglibc] Fix testing for existing files

To test for existing files, use "[ -f blabla ]", not "[ -a blabla ]"
Checking for a file exsitence with "-a" is a bashism.
Althoug we _are_ using bash, it's disturbing as it can be misread as
the 'and' operator. Fix by using "-f".

samples: add eglibc-based toolchain for MIPS.

config: add Linux kernel 2.6.30.5

config: update Linux kernel long-term stable to 2.6.27.31.

Merge the AVR32 support branch to the default branch.

Removed debug line

Fix libc config

Misc AVR32 cleanups.

Changed copyright

Update README on how to send proper patches

Add a few lines of explanations on how to correctly setup
and use Mercurial to send proper patches.
