Do not prompt for the type of floating-point support, if the
architecture did not explicitly stated that it did support it.

Changeset #149c33923f47 broke the architectures that do not
support the --with-float=X ./configure flag (in gcc). For example,
x86_64 does not support it.
Add a new blind config option that architectures can set to tell
they support floating point selection.

First, 'SUPPORT' should be spelled 'SUPPORTS'.
Second, 'SUPPORT_XXX' really means 'supports --with-xxx', so rename the
affected options accordingly. Update the affected archs to match the new
namings.

Some architectures support a mixed hard/soft floating point, where
the compiler emits hardware floating point instructions, but passes
the operands in core (aka integer) registers.
For example, ARM supports this mode (to come in the next changeset).
Add support for softfp cross compilers to the GCC and GLIBC
configuration. Needed for Ubuntu and other distros that are softfp.

With the upcoming softfp support, the case..esac test would become
a bit convoluted if it were to test three different booleans.
Introduce a new blind string config option that defaults to the
selected floating point type used.

kconfig bools are disabled by default, so specifying 'default n' is useless and
noisy. This patch removes all occurrences of 'default n'.

Re-organise the sub-menu so that:
- the archs list comes first,
- followed by archs generic options
- followed by archs specific options

Move the arch-specific options to the second-part of
the generated files, so they appear after the generic
options, but before the optimisations.

Some components have configuration options that can depend on
generic options, so they should go below those.
uClibc for example:
- has its own options (wchar...)
- uses the generic options (threads...)
- if linuxthreads chosen, offers two impls
So we need to be able to split the components options in 2,
one part that is above the generic options, and one part that
ends up below the generic options.
|
|
Always enclose the sourced file between double-quotes (purely for
consistency; enclosing or not are both allowed by the kconfig language).
|
|
|
|
|
|
Add new hidden config knobs that architectures can select to
say whether they support 32- or 64-bit variants, and which
they default to.

- merge Linux and uClinux back to a single kernel
- add ARCH_USE_MMU and acquainted config options that
architectures can auto-select
- make binutils and elf2flt two "Binary utilities" that
go in a single common sub-{menu,directory} structure

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.

they want:
- CT_ARCH_CC_CORE_EXTRA_CONFIG
- CT_ARCH_CC_EXTRA_CONFIG
- CT_ARCH_TARGET_CLFAGS
- CT_ARCH_TARGET_LDFLAGS
This will hopefully enable architectures to specify specific flags.
PowerPC will need them to introduce SPE (coming RSN).

endian, others default to little endian.
Make this possible in the target selection menu.
|
|
Rationale:
Most of the time, soft-float problems are caused by this sucker of gcc:
it has support for soft float for all of the targets I've tried so far,
but does not activate this code until you dwelve into half a dozen of
files to make it accept to build and link the support code...
So, yes: gcc has soft-float support. And again, yes: gcc is a sucker.

sub-menu.
|
|
But mark build a native gdb as being EXPERIMENTAL.
|
|
That still leaves the linuxthreads stuff broken, but it was just before. I don't care anyway. Time to fix that later...
|

|
|
- associated patch set
- update the munging function to accomodate the new config variables
libfloat version was missing from the previous commit... :-(
Better handle the case where the sample directory already exist but isn't under revision control, and in case the destination file doesn't exist in the sample directory.
|
|
- 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.
|

You might just say: 'Yeah! crosstool-NG's got its own repo!".
Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup.
That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(
