MIPS supports two different NaN encodings, legacy and 2008. Information
about MIPS NaN encodings can be found here:
https://sourceware.org/binutils/docs/as/MIPS-NaN-Encodings.html
NaN legacy is the only option available for R2 cores and older.
NaN 2008 is the only option available for R6 cores.
R5 cores can have either NaN legacy or NaN 2008, depending on the
implementation. So, if the user selects a generic R5 target architecture
variant, we show a choice menu with both options available. For well
known R5 cores we directly select the NaN enconding they use.

libgcc_s.so is now added to TOOLCHAIN_EXTERNAL_LIBS for glibc/uclibc
in one place, and for musl in another place. Bottom line: it should be
in TOOLCHAIN_EXTERNAL_LIBS unconditionally.
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Currently, for the dynamic loader, we're copying ld*.so* for glibc and
uClibc, except for glibc/EABIhf where we are explicitly copying
ld-linux-armhf.so.*. For musl, we're not copying the dynamic linker
because it's simply a symbolic link to libc.so. However, the name of
the musl dynamic linker changes from one architecture to the other,
and we don't handle all cases.
Since handling the musl dynamic linker symlink creation is becoming
more and more annoying to maintain, this commit makes musl use the
same mechanism as glibc/uClibc: put the dynamic linker in
TOOLCHAIN_EXTERNAL_LIBS.
In addition, the special condition on glibc/EABIhf was added in
11ec38b695 ("toolchain-external: fix
Linaro ARM toolchain support") because an old Linaro toolchain had two
dynamic loaders, and we wanted to copy only one. But 1/ this is old
and 2/ having the two dynamic linkers doesn't really matter.
So this commit simply unconditionally adds "ld*.so*" to
TOOLCHAIN_EXTERNAL_LIBS, regardless of the C library being chosen. It
re-uses the musl dynamic linker symlink from the sysroot, which makes
it always correct, and allows us to remove the
TOOLCHAIN_EXTERNAL_MUSL_LD_LINK hook, and all the related logic.
This commit therefore solves two problems with the musl dynamic linker
symbolic link creation logic:
1 We support all architectures, without having to hardcode in
Buildroot the mapping between the CPU architecture and the
corresponding dynamic linker name. For example, our current logic
was not handling the mips64+n32 ABI case, where the dynamic linker
is named ld-musl-mipsn32el.so.1.
2 We support Crosstool-NG musl toolchains, where the dynamic linker
is in /lib, but libc.so is in /usr/lib.

This commit therefore replaces:
- https://patchwork.ozlabs.org/patch/780411/ (was another solution
for solving problem 1 above)
- https://patchwork.ozlabs.org/patch/763977/ and
https://patchwork.ozlabs.org/patch/748974/ (was another solution
for solving problem 2 above)
We currently use $(HOST_DIR)/usr as the prefix for host packages. That
has a few disadvantages:
- There are some things installed in $(HOST_DIR)/etc and
$(HOST_DIR)/sbin, which is inconsistent.
- To pack a buildroot-built toolchain into a tarball for use as an
external toolchain, you have to pack output/host/usr instead of the
more obvious output/host.
- Because of the above, the internal toolchain wrapper breaks which
forces us to work around it (call the actual toolchain executable
directly). This is OK for us, but when used in another build system,
that's a problem.
- Paths are four characters longer.
To allow us to gradually eliminate $(HOST_DIR)/usr while building
packages, replace it with a symlink to .
The symlinks from $(HOST_DIR)/usr/$(GNU_TARGET_NAME) and
$(HOST_DIR)/usr/lib that were added previously are removed again.
Note that the symlink creation will break when $(HOST_DIR)/usr
already exists as a directory, i.e. when rebuilding in an existing
output directory. This is necessary: if we don't break it now, the
following commits (which remove the usr part from various variables)
_will_ break it.
At the same time as creating this symlink, we have to update the
external toolchain wrapper and the external toolchain symlinks to go
one directory less up. Indeed, $(HOST_DIR) is one level less up than
it was before.

The input to copy_toolchain_lib_root is not one library, not a list of
libraries, but a library name pattern with glob wildcards.
This pattern is then passed to 'find' to get the actual list of libraries
matching the pattern. Reflect this using an appropriate variable name.
Note: if the root of the buildroot tree contains a file matching one of
these library patterns, the copying of libraries from staging to target will
not be correct. It is not impossible to fix that, e.g. using 'set -f', but
maybe it's not worth it.

The toolchain from the Cavium Octeon SDK has a sysroot layout as follows:
./lib32
./lib32/octeon2
./lib32-fp
./lib64
./lib64/octeon2
./lib64-fp
./usr
./usr/lib
./usr/lib32
./usr/lib32/octeon2
./usr/lib32-fp
./usr/lib64
./usr/lib64/octeon2
./usr/lib64-fp
./usr/bin
./usr/bin32
./usr/bin32-fp
./usr/bin64-fp
./usr/libexec
./usr/libexec32
./usr/libexec32-fp
./usr/libexec64-fp
./usr/sbin
./usr/sbin32
./usr/sbin32-fp
./usr/sbin64-fp
./usr/include
./usr/share
./sbin
./sbin32
./sbin32-fp
./sbin64-fp
./etc
./var
with the following selections:
- lib64 : default
- lib64/octeon2 : -march=octeon2
- lib64-fp : -march=octeon3
- lib32 : -mabi=n32
- lib32/octeon2 : -mabi=n32 -march=octeon2
- lib32-fp : -mabi=n32 -march=octeon3
In case of '-mabi=n32 -march=octeon2' (but same is true for n64+octeon2)the
original Buildroot toolchain logic would copy both the libraries in
lib32 as the subdirectory lib32/octeon2, which means that every library is
installed twice (but only one of each is really needed).
While ARCH_LIB_DIR is determined by the location of libc.a, which in this
case is effectively:
<sysroot>/usr/lib32/octeon2/libc.a
the variable only retains 'lib32' and not 'lib32/octeon2' as expected.
To make Buildroot cope with this style of toolchain layout, we need to adapt
the calculation of ARCH_LIB_DIR to also include the second part.
This, in turn, means that ARCH_LIB_DIR is no longer guaranteed to be a
singular path component, resulting in some additional changes.
Certain older Linaro toolchains actually had the same layout. Libraries were
located in lib/<tuple> rather than lib directly. Previously, this was
handled by adding a toolchain-specific fixup that creates a symlink
lib/<tuple> -> lib, but with this patch this would no longer be needed.
Note that one difference with the Octeon case is that these Linaro
toolchains are not actually multilib, i.e. there is just one location with
the libraries and thus there is no problem with duplicated libraries.

Normally, the Buildroot toolchain logic copies all required libraries from
the external toolchain to the staging directory, including the dynamic
loader ld-*.so.
There are cases, however, where the dynamic loader is _not_ automatically
copied to staging. This happens when the dynamic loader is not inside
ARCH_LIB_DIR itself (e.g. lib64), but instead resides in 'lib' (assume, of
course, that ARCH_LIB_DIR != 'lib').
Currently, this is fixed in a toolchain-specific fixup, e.g. by recreating a
missing symlink or copying over a missing file. Such toolchain specific
fixups are not very nice.
Moreover, in a subsequent patch, the value of ARCH_LIB_DIR changes for some
toolchains, causing them to have the same problem of a missing dynamic
loader. This used to be the case for older Linaro toolchains with libraries
in 'lib/<tuple>': Buildroot used to set ARCH_LIB_DIR=lib but the mentioned
patch changes it to 'lib/<tuple>' instead. As a result, the files directly
under 'lib/' will no longer be copied. There should be none, but the dynamic
loader is a notable exception.
[Note: support for these older Linaro toolchain has been removed in 2016.11]
Instead, copy over the ld.so file(s)/link(s) from the extracted toolchain
into staging, in the central copy_toolchain_sysroot function. The existing
toolchain logic will then handle the copy of these files from staging to
target.
This means the toolchain-specific fixups can be removed.

We currently support gcc as old as 4.3. However, Buildroot works
perfectly well with even older gcc versions (tested with 4.1). So we
can add an option BR2_TOOLCHAIN_EXTERNAL_GCC_OLD to support that. The
help text of this option is written with plenty of discouragement.
We use _OLD and not something like _PRE_4_3, because at some point we
will likely remove the 4.3 option and what would then require a name
change.
We don't set any _AT_LEAST option in this case because it's no use -
there is no lower bound on the version in this case. We therefore leave
BR2_TOOLCHAIN_GCC_AT_LEAST empty (the implicit default). When it is
empty, we don't do a version check at all in check_gcc_version

The toolchain-external-package infrastructure is just a copy of the
toolchain-external commands, replacing TOOLCHAIN_EXTERNAL by $(2)
and adding double-dollars everywhere.
toolchain-external itself is converted to a virtual package, but it
is faked a little to make sue the toolchains that haven't been
converted to toolchain-external-package yet keep on working.
The TOOLCHAIN_EXTERNAL_MOVE commands don't have to be redefined
for every toolchain-external-package instance, so that is moved
out into the common part of pkg-toolchain-external.mk.
The musl-compat-headers dependency stays in the toolchain-external
package itself.
The musl ld link is duplicated in the legacy toolchain-external and
the toolchain-external-package, because they have separate hooks.
The handling of TOOLCHAIN_EXTERNAL_BIN deserves some special attention,
because its value will be different for different
toolchain-external-package instances. However, the value only depends
on variables that are set by Kconfig (BR2_TOOLCHAIN_EXTERNAL_PREFIX
and BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD) so it can easily be used in
the generic part. So we don't have to do anything specific for this
variable after all.

ARCH_SUBDIR is computed based on the value of ARCH_SYSROOT_DIR and
SYSROOT_DIR. For nested toolchains ARCH_SYSROOT_DIR is a subdir of
SYSROOT_DIR, so a sed command like this one...
sed -r -e "s:^${SYSROOT_DIR}(.*)/$:\1:"
...basically removes the leading SYSROOT_DIR part from ARCH_SYSROOT_DIR.
But, for side-by-side sysroot toolchains ARCH_SYSROOT_DIR and
SYSROOT_DIR are at the same level, so the above sed command doesn't
make any effect.
This patch therefore improves the calculation of ARCH_SUBDIR to
clearly handle the three possible cases:
- There is a single sysroot, or the selected architecture sysroot is
the main one (i.e SYSROOT_DIR == ARCH_SYSROOT_DIR). In this case,
ARCH_SUBDIR is empty.
- There are side-by-side sysroots, such as
SYSROOT_DIR=.../sysroot/mips-r2-hard/ and
ARCH_SYSROOT_DIR=.../sysroot/mipsel-r2-hard/.
- The arch-sysroot is nested, such as SYSROOT_DIR=.../sysroot and
ARCH_SYSROOT_DIR=.../sysroot/armv4t/

On some architectures (namely x86-64), glibc may provide a libmvec
library since glibc 2.22, which programs built with gcc OpenMP support
might get linked to.
In order for these programs to work on the target, we need to copy
this library to the target filesystem.
This commit takes care of this for the external toolchain
situation. Note that libraries listed in TOOLCHAIN_EXTERNAL_LIBS are
silently ignored if they don't exist. Therefore, we don't need to have
any condition on the architecture or glibc version.

This reverts commit a0aa7e0e17 and reworks
the code to fix a major and potentially catastrophic bug when the
following conditions are met:
- The user has selected a "known toolchain profile", such as a Linaro
toolchain, a Sourcery CodeBench toolchain etc. People using "custom
toolchain profile" are not affected.
- The user has enabled BR2_TOOLCHAIN_EXTERNAL_PREINSTALLED=y to
indicate that the toolchain is already locally available (as
opposed to having Buildroot download and extract the toolchain)
- The user has left BR2_TOOLCHAIN_EXTERNAL_PATH empty, because his
toolchain is directly available through the PATH environment
variable. When BR2_TOOLCHAIN_EXTERNAL_PATH is non-empty, Buildroot
will do something silly (remove the toolchain contents), but that
are limited to the toolchain itself.
When such conditions are met, Buildroot will run "rm -rf /*" due to
TOOLCHAIN_EXTERNAL_INSTALL_DIR being empty.
This bug does not exist in 2016.05, and appeared in 2016.08 due to
commit a0aa7e0e17.
Commit a0aa7e0e17 removed the assignment
of TOOLCHAIN_EXTERNAL_SOURCE and TOOLCHAIN_EXTERNAL_SITE to empty, as
part of a global cleanup to remove such assignments that supposedly
had become unneeded following a fix of the package infrastructure
(75630eba22: core: do not attempt
downloads with no _VERSION set).
However, this causes TOOLCHAIN_EXTERNAL_SOURCE to be non-empty even
for BR2_TOOLCHAIN_EXTERNAL_PREINSTALLED=y configuration, with the
following consequences:
- Buildroot downloads the toolchain tarball (while we're saying the
toolchain is already available). Not dramatic, but clearly buggy.
- Buildroot registers a post-extract hook that moves the toolchain
from its extract directory (output/build/toolchain-external-.../ to
its final location in host/opt/ext-toolchain/). Before doing this,
it removes everything in TOOLCHAIN_EXTERNAL_INSTALL_DIR (which
should normally be host/opt/ext-toolchain/).
Another mistake that caused the bug is commit
b731dc7bfb ("toolchain-external: make
extraction idempotent"), which introduce the dangerous call "rm -rf
$(var)/*", which can be catastrophic if by mistake $(var) is
empty. Instead, this commit should have just used rm -rf $(var) to
remove the directory instead: it would have failed without consequences
if $(var) is empty, and the directory was anyway already re-created
right after with a mkdir.
To address this problem, we:
- Revert commit a0aa7e0e17, so that
_SOURCE and _SITE are empty in the pre-installed toolchain case.
- Rework the code to ensure that similar problems will no happen in the
future, by:
- Registering the TOOLCHAIN_EXTERNAL_MOVE hook only when
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y, since moving the toolchain is
only needed when Buildroot downloaded the toolchain.
- Introduce a variable TOOLCHAIN_EXTERNAL_DOWNLOAD_INSTALL_DIR which
is the path in which Buildroot installs external toolchains when it
is in charge of downloading/extracting them. Then, the
TOOLCHAIN_EXTERNAL_MOVE hook is changed to use this variable, which
is guaranteed to be non-empty.
- Replace the removal of the directory contents $(var)/* by removing
the directory itself $(var). The directory was anyway already
re-created if needed afterwards. Thanks to doing this, if $(var)
ever becomes empty, we will do "rm -rf" which will fail and abort
the build, and not the catastrophic "rm -rf /*".

musl provides neither sys/queue.h nor sys/cdefs.h. Those two headers are
however quite widely used in a lot of packages (though they should at
least not use cdefs.h which is only full of mostly-legacy macros, and
which is mostly an internal header of glibc and was never really meant to
be exposed to, and used by packages).
But we don't live in an ideal world, so a lot of packages break when
those two headers are missing.
We already took care of sys/queue.h with the netbsd-queue package. But
the need for cdefs.h is getting more and more pressing.
We rename the netbsd-queue package into musl-compat-headers, and we
make it install sys/queue.h (from NetBSD) and sys/cdefs.h (a minimalist
one we bundle in Buildroot). We can't use the cdefs.h from NetBSD
because it includes machine-dependent headers; instead we bundle a very
minimalistic one, that covers only what we need.
