Currently, we rely on an existing external cross-compiler targetting
the target, to build the C library.
This can pause quite a few problems if that compiler is different from
the one we are building, because it could introduce some ABI issues.
This patch removes this dependency, by building the core compilers
as we do for standard cross, and also by building the binutils and
gcc, for running on the build machine.
This means we no longer need to offer the cross-sompiler selection in
the menuconfig.

Currently, we check host feature in ./configure. This works only for
cross toolchains, but not for canadian toolchains. ./configure has
absolutely no way to know what the host for the toolchain will be;
only the build scripts know.
So, move the headers & libraries checks from ./configure to the build
scripts, early enough in the build, but not before we know the host
compiler and other tools.

"crosstool-NG-${CT_VERSION}" is currently the default for TOOLCHAIN_PKGVERSION,
and this options is passed as is to --with-pkgversion.
This patch prepends "crosstool-NG ${CT_VERSION}" to TOOLCHAIN_PKGVERSION before
passing it to --with-pkgversion.

Hide the staticaly linked libstdc++ option if the static libstdc++ is not
present, detected at configure time.
Add a blind option that says whether static linking is possible at all.
It defaults to 'y', but depends on the needed CONFIGURE_* options. For
now, it only depends on static libtdc++, but new dependencies can be
easily added.
Hide the global static toolchain option behind this new option.

This patch promotes the PKGVERSION and BUGURL options to toolchain level so that
all toolchain components supporting them can benefit from them.
These options are passed to configure through --with-pkgversion and
--with-bugurl.
They are supported by binutils 2.18+, gcc 4.3+, eglibc 2.9+ and gdb 7.0+.

In backend mode, setting the sysroot name is the
responsibility of the upper-layer build system.

Use of the sysroot is highly recommended, and the non-sysroot case is
both obsolete and not widely tested.
Before the non-sysroot case can go away, deprecate it.

Depending on local policies, some users have expressed a need to
have the sysroot be named differently than the hard-coded name.
Add an option for that.
Default to 'sysroot' to match the existing literature.
While at it, replace 'sys-root' with 'sysroot' everywhere we
reference the sysroot.

Add a config option to statically build the host tools.
Impacted tools can use that option to decide wether to build
statically or shared.
For now, no tool uses it, but they'll be added one at a time
in the next commits.

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.
|
|
Note however that some configurations (eg. arm-elf) will still
have the vendor part 'unknown' forced in (by config.sub).
|
|
Move the tools wrapper choice selection down to the companion libraries
sub-menu, to avoid the user going back and forth in the menu.
|
|
The tools wrapper is not needed only for canadian crosses, but also
for every other type of toolchain.
|
|
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.
|
|
Now that all kernels that support shared libraries select the correct config
option, we can change the dependency rules of SHARED_LIBS accordingly.
|
|
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.
|
|
Offer a config choice on whether to isntall the script wrapper, or
the compiled C wrapper. Update docs/overview.txt accordingly.
|
|
Add implementation for a candadian build option already
present in crosstool in order to build a cross-compiler
where build != host != target

This should ultimately llow to build bare-metal compilers, for targets that have no kernel and no C library.
Move the C library build script to their own sub-directory; introduce an empty build script for bare-metal.
Move the compiler build script to its own sub-directory.
Move the kernel build script to its own sub-directory; introduce an empty build script for bare-metal.
Update the ARM target tuples to enable bare-metal targets.
Add two ARM bare-metal samples.
Add latest Linux kernel versions.

- the threading models available are dependent on the C library used
- it is thus easier to first select the C libary, and then the threading model, rather going back to the toolchain menu.

- add a framework to easily add new ones
- add gdb as a first debug facility
- add patches for gdb
After the kernel checked its installed headers, clean up the mess of .checked.* files.
Reorder scripts/crosstool.sh:
- dump the configuration early
- renice early
- get info about build system early, when setting up the environment
- when in cross or native, the host tools are those of the build system, and only in this case
- elapsed time calculations moved to scripts/functions
Remove handling of the color: it's gone once and for all.
Update tools/addToolVersion.sh:
- handle debug facilities
- commonalise some code
- remove dead tools (cygwin, tcc)
Point to my address for bug reports.

|
Some fixups in config entries, to avoid warnings when parsed by the kconfig parser.
|
|
- log level boost for warnings and errors
- option re-ordering
- help updating
|

Add the four types of toolchains ct-ng is able to build as EXPERIMENTAL, except for CROSS which *is* functional.
Reorder menus accordingly.
