755de234cb elf2flt: use CT_ARCH to set target CPU, not CT_TARGET
CT_TARGET is composed as "${CT_ARCH}${CT_ARCH_SUFFIX}", so CT_TARGET may
become something like "armv7", for example. This is used by the configure
script to set the "CPU" variable in the Makefile, leading to a commad line
containing

    -DTARGET_armv7 -DTARGET_CPU="armv7"

In this case the compilation of elf2flt.c fails with "Don't know how to
support your CPU architecture??". Passsing "CPU=${CT_ARCH}" in the make
command line overrides the configured value and solves the problem.

Alexey Neyman
7a94c81e5b Rework configure logic wrt GNU autotools
Rather than requiring them of a certain version, detect if they are present
(and have sufficient version) and select an appropriate companion tool
otherwise. The reason is that, for example, most recent gettext requires
automake 1.15, but the newest available CentOS has 1.13. Hence, the option
to "upgrade your system" does not apply, and the warning comment above
the companion tools is rather scary.

With this approach, it will work out of the box - either by using the host's
tools, or by building them as needed. Note that the user can still change
the setting in the config.

While there, propagate the new version checking macro to awk/bash/host binutils,
and switch from --with-foo=xxx to officially blessed FOO=xxx: the latter
does not require checking for bogus values (i.e., --with-foo, --without-foo)
and AC_PROG_* macros recognize the corresponding settings without further
modifications. For now, I kept --with-foo=, if only to complain and steer
people to the new way. To be cleaned up after a release.

3dbb576c17 Make companion libs static.
This follows the trend set by 1*.sh scripts that configure ISL, GMP,
MPFR, CLooG, etc. Building with shared libraries presents all kinds
of problems:
- The shared libraries need to be installed into ${CT_PREFIX_DIR}.
- The binaries linked against companion libs need to have proper
RPATH, or they're looking for shared libs in
.build/${CT_PREFIX}/buildtools/lib.
- All libraries must agree as to whether they're built shared,
static, or both. Otherwise, gettext tries to link in static libncurses.a
into a shared library and fails (since libncurses was compiled without
the -fPIC switch and hence contains relocations that cannot be handled
in a shared library).

So this fixes the current mess. If we decide to re-enable building
the companion libs shared, we should probably make this dependent on
a separate suboption of CT_STATIC_TOOLCHAIN.

Add a config loosely based on one reported in the issue 274.

2091c5dd2d Pass FOR_BUILD flags when building the pass-1/2 core GCC.
Current build passes {CFLAGS,LDFLAGS}_FOR_HOST - which breaks canadian cross
(e.g. tried building for x86_64-unknown-linux-uclibc host). This dates
back to the days of yore when CFLAGS were set directly in the do_gcc_core_backend
(and that function is used as the final gcc's backend).

do_gcc_core_backend is now passed with CFLAGS/LDFLAGS to use, so let
the pass-1/pass-2/final-for-build steps pass the appropriate flags.

6c6829a061 xtensa: fix endianness support
To build uClibc correctly we need correct endianness selected in the
crosstool-NG. Xtensa cores may be little- or big-endian, but this
property is static. The toolchain knows the core endianness and doesn't
need options to select it.
Enable ARCH_SUPPORTS_BOTH_ENDIAN and select LE by default. Specify empty
CT_ARCH_ENDIAN_CFLAG so that -m{big,little}-endian don't get added to
the TARGET_CFLAGS, as it's not supported by gcc. Specify empty
CT_ARCH_ENDIAN_LDFLAG so that -EB/-EL don't get added to the
TARGET_LDFLAGS as they are ignored. Select big-endian in the example
xtensa-unknown-linux-uclibc configuration.

This fixes uClibc toolchain build for little-endian cores.

87bfd55b3b Give companion tools some love.
Allow selection of make/m4/... version. Support imports of new versions
via addToolVersion.sh. Import newest versions of the companion tools.

One non-trivial change is the handling of make versions. Existing code
was not handling make companion tool as described (see the previous
commit). However, since most modern systems have make 4.x, that previous
commit made crosstool-ng always build make as a companion tool.

This traces back to the commit dd15c93 from 2014. That commit's log message
says that actually it was 3.81 which broke the build for certain component
(it was originally breaking eglibc, but I noticed it was breaking current
glibc on powerpc64), and introduced an option to force using 3.81 by
"components that really need it". It looks like in 2.5 years we haven't
seen any such components that really need make 3.81, and (given that make
has already had a few releases since 3.81) we're unlikely to see them
in the future.

Hence, the configure check is changed from "exactly 3.81" to "3.81 or newer".
In its current form, configure will accept make 3.80+, and will not require
make as a companion tool for 3.81+. We might want to bump the latter check
to even newer version given the claim from dd15c93. Killed
COMP_TOOLS_make_3_81_NEEDED.

Anyway, I retained 3.81 just in case; ditto for m4 1.14.3, autoconf 2.65
and automake 1.11.1.

488b27f58b Partially revert 6f8e89cb5c.
The referenced commit replaced 'make' with '${make}' everywhere. This is
wrong for at least the utilities that we may build as companion tools
(make, libtool): this will always invoke the version detected by configure
by supplying the absolute path. In other words, the wrappers in
.build/tools/bin are not fallbacks - they are either temporary (in case
a respective companion tool is built) or permanent redirectors.

This is the reason why the PATH= has .build/*/buildtools/bin at higher
precedence than .build/tools/bin; the latter has the versions detected by
configure and the former has the versions built as companion tools.

Revert the rest of the gang (grep/sed/...) for consistency. After all,
we may decide to supply some of them as well (awk, for instance).

1. Check if anything was installed outside sysroot; on some [baremetal only?]
configurations GCC doesn't install anything to ${CT_PREFIX_DIR}/${CT_TARGET}/lib.
2. We need to create <sysroot>/lib/<multilib> if it doesn't exist
(MUSL only installs in <sysroot>/usr/lib).
3. Do not move the linker scripts; elf2flt expects to find them
in gcc's dir, not sysroot.

8121be5b21 Fix m68k with uClibc-ng >= 1.0.15.
1.0.15 only kept a single LINUXTHREADS option, and renamed it, making it
no longer option-compatible with uClibc.

The option for "1.0.14 or later" version of uClibc-ng is not currently
used; rename it to "1.0.15 or later" and use it to handle newer
uClibc-ng's linuxthreads.

m68k happens to be the only sample using linuxthreads.

10972baa20 binutils: make symlinks in a consistent way
On the stage "core gcc pass-2" the following layout is created:

1) buildtools/bin/TARGET-{ar,as,elf2flt,flthdr,ld,ld.bfd,ranlib,strip}
2) buildtools/TARGET/bin/{ar,as,elf2flt,flthdr,ld,ld.bfd,ranlib,strip}
3) x-tools/TARGET/bin/TARGET-{ar,as,elf2flt,flthdr,ld,ld.bfd,ranlib,strip}
4) x-tools/TARGET/TARGET/bin{ar,as,elf2flt,flthdr,ld,ld.bfd,ranlib,strip}

where both (1) and (2) are symlinks to (3). This effectively renders
core pass-2 gcc with elf2flt linker unusable.

This patch fixes libexpat detection for gdb-native and
gdb-cross static builds.

For gdb-native build configure should not touch system
/usr/{lib,include} directories while looking for libexpat.
To fix this we pass --without-libexpat-prefix flag
to configure script.

For gdb-cross build configure is allowed to investigate
system /usr/{lib,include} directories, but it does not
hurt to disable this behavior. In this case configure
falls back to -lexpat, which works as expected.

3ebc5d0c1e libc/*.sh: Deprecate libc_check_config step.
This step was only used in uClibc. However, with upcoming multilib, the
config management will have to be done for each variant differently,
anyway.

uClibc was the only user of libc_check_config step, as well as
CT_CONFIG_DIR directory. Retire these.

Two other clean-ups in uClibc.sh:
- KERNEL_HEADERS check seems to be bogus, this config option is not
  present even in 0.9.30 - which is not supported already.
- SHARED_LIB_LOADER_PREFIX was renamed to MULTILIB_DIR in 0.9.31,
  according to ChangeLog - and MULTILIB_DIR is passed from command line
  instead.

43c303c946 libc/*.sh: handle combinations of multilib root/dir.
Install startfiles for libc variants into the most specific combination
(suffixed sysroot, if applicable + suffixed multi-os dir, if
applicable). Install headers once in every suffixed sysroot (although it
seems that GCC picks up headers from top-level sysroot, GCC manual
claims that sysroot suffix affects headers search path).

In uClibc, this requires a better sanitization of the directory: it
creates symlinks from {sysroot}/usr/lib/{multi_os_dir} to
{sysroot}/lib/{multi_os_dir} and to do so, it counts the number of path
components in the libdir. This breaks if one of such components is `..'
- symlinks contain an extra `../..' then. Since such sanitization had to
be implemented anyway, use it in other places to print more sensible
directory names.

Also, fix the description of configure --host/--target per musl's
configure help message (and its actual code).

82072d0cbc multilib: Determine which options may pass through.
On some arches (e.g. MIPS) the options like -mabi do not work if
specified more than once (see the comment in 100-gcc.sh). Therefore,
we need to determine which of the options produced by <arch>.sh can
be passed to multilib builds and which must be removed (i.e., which
options vary among the multilibs).

This presents a chicken-and-egg problem. GCC developers, in their
infinite wisdom, do not allow arbitrary multilib specification to be
supplied to GCC's configure. Instead, the target (and sometimes some
extra options) determine the set of multilibs - which may include
different CPUs, different ABIs, different endianness, different FPUs,
different floating-point ABIs, ... That is, we don't know which parts
vary until we build GCC and ask it.

So, the solution implemented here is:
- For multilib builds, start with empty CT_ARCH_TARGET_CFLAGS/LDFLAGS.
- For multilib builds, require core pass 1. Pass 1 does not build any
  target binaries, so at that point, our target options have not been
  used yet.
- Provide an API to modify the environment variables for the steps that
  follow the current one.
- As a part of multilib-related housekeeping, determine the variable
  part of multilibs and filter out these options; pass the rest into
  CT_TARGET_CFLAGS/LDFLAGS.

This still does not handle extra dependencies between GCC options (like
-ma implying -mcpu=X -mtune=Y, etc.) but I feel that would complicate
matters too much. Let's leave this until there's a compelling case for
it.

Also, query GCC's sysroot suffix for targets that use it (SuperH,
for example) - the default multilib may not work if the command line
specifies the default option explicitly (%sysroot_suffix_spec is not
aware of multilib defaults).

This was untidy and incorrect for multilib (the bitness of

c7da54edf4 glibc: Use common arch call to get multilib targets
The previous patch added the function 'CT_DoMultilibTarget()' to
scripts/build/arch/*.sh.

This patch calls the common function to (currently) get just the target
tuple for the current multilib target.

This patch was originally by: Cody P Schafer

Changed by Alexey Neyman: first, try `gcc -print-multiarch`. If it is
supported, use whatever it reports. Otherwise, fall back to our
guesswork. Move "i486" quirk into glibc.sh, as it is specific to glibc
(e.g. uclibc will need i386, which is what GCC reports).

34ecc718d9 arch/all: Add common function to return multilib target
This code was abstracted out of Cody P Schafer's multilib patch.
It doesn't seem right having architecture dependent code in a
specific libc implementation script. So this patch breaks it out into
scripts/build/arch/<arch>.sh in a function:

  multilib_target_to_build="$(CT_DoArchMultilibTarget 'multi_flags'
'target-in')"

Note that this function gets called on each multilib variant with
different sets of compiler flags supplied in 'multi_flags'. The caller
will first filter the flags so that there is no conflicting flags (e.g.,
no '-m32 -m64') supplied.

Changed by Alexey Neyman:
- make option analysis check specific option rather than match global
  options string as a whole. Moreover, old code did not handle multiple
  options in the same multilib, e.g. '-m64 -mlittle'.
- fixed substitutions in powerpc.sh (*le variants did not match the
  pattern in the shell parameter expansion)
- make s390.sh actually apply the flags it gathered from the options.
- straighten the spaghetti in x86.sh by setting two flags, arch & abi.
  Also, do not depend on "gnu" being the last part - we can have
  '*-uclibcx32', for example.

v9 is such a "non-UltraSPARC-I+ ISA CPU", so it makes no sense to
default to v9 when targetting Linux.

it checks for <prefix>/lib/libexpat.so and finding that, attempts to

obviously fails (.so cannot be statically linked), so configure assumes
libexpat is unusable. Thus, --with-libexpat-prefix is dangerous and
should be avoided; instead, configure should find the libraries via the
supplied CC/LD definitions.

9820e4eea5 musl-libc: Rewrite musl.sh build script
This commit moves the do_libc_configure function to do_libc_backend and
switches do_libc_start_files and do_libc_final to call do_libc_backend.

The major reason for the rewrite is that musl => 1.1.13 has had it's own
build system rewritten and can now build out-of-tree.

ec9af46847 glibc: Mirror extra_config flags from do_libc_backend_once

```
              # Also, if those two are missing, iconv build breaks
              extra_config+=( --disable-debug --disable-sanity-checks )

But in do_libc_locales we only add ```--disable-debug```.

mirror this, as I've seen iconv break this way.

644522fcd0 libiconv: configure with --disable-nls
On Windows a build failure can be triggered during the
build of the static iconv if a dynamic iconv is already
present:

There's a circular dependency between libiconv and gettext
which (on a system with a dynamic gettext (and thus iconv)
installed in the system prefix) causes a failure to build
iconv.exe statically if it is built with nls ..

.. Which needs gettext
.. which depends on libiconv
.. so libtool finds a dynamically linked libgettext.la
.. and therefore presents ld with the dll import library
     libiconv.dll.a when linking iconv.exe
.. as well as the static libiconv.a that it has just built!
.. leading to multiply defined symbols from iconv.

Therefore, we build it without nls. If it later turns out
that we need it to be built with nls, then I will have to
build it in two passes (common practice when bootstrapping
GNU/Linux distros, MSYS2 and probably Cygwin and Homebrew).

2a89c32193 gcc: Remove gcc <= 4.7.x
As per #222, in crosstool-NG >= 1.23.0, we will only support:

 [upstream supported gcc versions] - 1

As of this writing, these versions are:

* 5.2.0
* 4.9.3
* 4.8.5 (the -1, since development on 4.8.x is now closed)

I plan to keep 4.8.5 around because of some architectures having issues
with over-optimization or just faulty optimization in the 4.9.x and
possibly newer versions.

I also cleaned up a requirement for glibc to depend on >= gcc-4.6.x for
>= glibc-2.20, but since the lowest gcc we support after this change is
>= 4.8.5, this condition can go away.

Patches for older gcc versions are removed in the next commit.

Because of the configurability, the build process requires one additional
step for gcc, binutils, and gdb to update the default configuration.
These configurations are packed into an 'overlay' tar image, and are
simply untarred on top of the default configuration during the build.

1a25115a18 gcc: Support only the latest branch releases of gcc
This change, as per #222, reduces the number of supported releases of
gcc to the latest branch releases.

I noticed while doing this work that gcc-4.5.4 was never added, so I
moved patches for gcc-4.5.3 to 4.5.4 and updated the
bfin-unknown-linux-uclibc example. Also, 120-siginfo.patch was fixed
upstream in the 4.5.4 release, so this patch is omitted.

I also bumped the avr sample to 4.9.3 from 4.9.2.

With the addition of gcc-5.x, the gcc release team now releases the
major.minor.0 versions, while updates to the branch are available in
svn/git. We'll address that when we get to issue #219. This change just
removes CC_GCC_5_1 and moves CC_GCC_5_2 to CC_GCC_5, and removes
CC_GCC_5_1_or_later and moves CC_GCC_5_2_or_later to CC_GCC_5_or_later.

This is the first of two part changes, as mentioned in #222.
This change is slated for release in 1.22.0. The next change will be
slated for 1.23.0, and will limit gcc versions to what is on
https://gcc.gnu.org under "Release Series and Status", which is
currently 4.9.3 and 5.2.0, although I will also support the previous
supported version. In this example that would be 4.8.5.

Last, but not least, this change also retires AVR32 support.

3bd86362ab Using "all" and "install" targets in do_gcc_core_backend if configured.
- New configurations:
  - CC_GCC_TARGET_FINAL:
    Use the default targets "all" and "install" for the final compiler for
    bare metal.
- Adding parameter "build_step" to function do_gcc_core_backend:
  do_gcc_core_backend is used for the core compiler and in case of bare metal
  for the final compiler, too. To have better control over the parameters for
  the final compiler "build_step" is used.
  - Used for proper logging.
  - Use CT_CC_GCC_CORE_EXTRA_CONFIG_ARRAY or CT_CC_GCC_EXTRA_CONFIG_ARRAY.
  - If CT_CC_GCC_TARGET_FINAL is set and the final compiler is build then the
    make targets for the final compiler are used ("all", "install").

b8e64a0c08 avr-libc: add support for avr-libc C library
This commit adds support for the avr-libc C library.
According to the project page at http://www.nongnu.org/avr-libc , the
avr-libc package provides a subset of the standard C library for Atmel
AVR 8-bit RISC microcontrollers. In addition, the library provides the
basic startup code needed by most applications.

Support for this library in crosstool-ng is only enabled for the AVR
8-bit target.

The avr-libc manual and most distributions build the AVR 8-bit gcc
toolchain with the "avr" (non-canonical) target.
Some experimentation also led to the conclusion that other (canonical)
targets are not very well supported, so we force the "avr" target for
crosstool-ng as well.

The manual also recommends building avr-libc after the final gcc build.
To accomplish this with crosstool-ng, a new do_libc_post_cc step is
added, in which currently only avr-libc performs its build, and is a
no-op for the other libc options.

230dc12285 avr: add support for AVR 8-bit architecture
This commit adds support for the Atmel AVR 8-bit RISC architecture.
This is the first 8-bit architecture to be added to crosstool-ng so the
configuration options for 8-bit architectures are added here as well.

gcc has had support for AVR for quite a while, at least since the 4.3
series for the currently popular ATmega microcontroler series.
The AVR architecture only supports bare-metal toolchains.

gcc for the AVR 8-bit architecture, usually referred to as avr-gcc, is
commonly used in conjunction with the avr-libc library which provides
additional resources for the Atmel AVR 8-bit microcontrollers.

avr-gcc can also be found as a supported package in some recent Linux
distributions.

This commit also closes #66

c88bbca7ab comptools/make: Install 'gmake' symlink
We had following problem: We're building a toolchain with an old glibc
version for compatibility with old Linux distributions (glibc 2.9). This
version requires make < 4 to build. However, the configure script of
glibc looks for make in the order "gnumake", "gmake" and "make". So when
"gmake" is available in the system (which is the case on Gentoo Linux
per default, unfortunately), then configure finds the system gmake 4.1
instead of the ct-ng make 3.82.

This patch adds an option to install a symlink so that 'gmake' is also
available in the old version when building toolchains.

linaro_version is a filter. If it is not a linaro toolchain, it will
just be CT_{CC,GDB}_VERSION. If it is a linaro toolchain, CT_{CC,GDB}_VERSION
will be prefixed with 'linaro-' and will not match linaro_version, as
linaro_version will just have the part after 'linaro-'.

This *really* fixes the issue :sigh:

For gcc and gdb, also separate out the linaro download locations so that
if you are downloading the linaro variant, it skips trying to download
from the official gcc mirror.

This commit closes #3

4125a79589 binutils: Fix elf2flt compile on more modern systems
Without this fix, elf2flt will blow up complaining that it can't resolve
dlopen() and friends.  One has to explicitly pass '-ldl' on the final
linking command line, because the system linker is not resolving
indirect dependent shared libraries.

I've needed to this patch for several years on Fedora systems.

f65ecce4ba binutils: Fixup the static toolchain build problem
When try to build the static toolchain, binutils failed.

    I have checked the libtool script, and found that the following option
          -all-static
          -static
          -static-libtool-libs

    are processed in a strange way. If any one of those three options
    appears firstly in the cmdline, all others will be neglected. Our
    LDFLAGS is ".... -static -all-static -o", so the -static option
    takes the real effect, and the -all-static has no useage actually!
    that is the cause of the failure.

* 1.1.4 (Mainline)

Futher improvements are needed.
* gcc-4.9.x has issues (Might be fixed in musl-1.1.4).
* Multilib support is needed.
* Checks to make sure paths are correct.
* Move to 2-step gcc build. 3-step build is not necessary.

Technically, I don't forbid powerpcle support either, but I'm not sure that

technically makes it possible).

powerpc64le needs glibc 2.19 and gcc 4.9. I haven't looked into the support
tools, but at least gdb 7.5 is too old (7.7.1 definitely has support).

Also make powerpc64 non-experimental. It's practically old at this point.

db2872f2ac cc/gcc: allow CC_EXTRA_CONFIG_ARRAY on baremetal
The final bare-metal compiler is built using the core backend.
Currently the core uses the CC_CORE_EXTRA_CONFIG_ARRAY variable.

While this works as supposed to, this can leave the user puzzled

the final options.

Only show the core options if any of the core passes are needed,
and use the final options in the core-backend if we're issuing

c6fd7bd2d9 cc/gcc: diable libsanitizer without NPTL
gcc-4.8 comes with a new library to sanitise memory access:
  - heap-, stack-, and global-buffer overflow, use-after-free
  - data-races between threads

This library requires some _np parts of the API, which are not
implemented in the (old) LinuxThreads, which is still available
in uClibc.

Since NPTL requires a i486 or above, i386 are stuck with using LT,
which precludes building the libsanitizer.

Disable libsanitizer, a bit like libatomic is.

e284b218a7 arch/avr32: Fix download of header files
This patch fixes the download of the avr32 headers in crosstool-ng by
fetching them directly from Atmel's web site instead of the now-broken URL
given by the original author of the avr32-header-fetching modification,
who fetched them from a copy on his own, now-defunct server.

It also adds the necessary logic to extract from a zip file, as that is
how the headers are packaged.

To configure it for avr32 after launching ct-ng menuconfig in an empty
directory:

       Paths and misc options ->
               Shell to use as CONFIG_SHELL = sh
       Target options ->
               Target Architecture = avr32
       Toolchain options ->
               Tuple's alias = avr32
       Binary utilities ->
               binutils version = 2.18a
       C compiler
               gcc version = 4.2.2
       C-library
               newlib version = 1.17.0
               Enable IOs on long long = yes
               Enable IOs on floats and doubles = yes
               Disable the syscalls supplied with newlib = yes

CONFIG_SHELL is necessary to get round the "fragment: command not
found" bug when binutils-2.18 is configured using bash.

Prepared against crosstool-ng mercurial trunk on 31 March 2012.
