# Super-H specific configuration file
config: fix recursive deps The latest kconfig stuff is more stringent when it comes to validating the dependency of the symbols. It is no longer possible to have a symbol depend on itself (such as our construct for arch/cc/libc/... was doing). Fix our generated-file infrastructure to avoid these situations when the new kconfig stuff will be merged (in a following changeset). Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>

Super-H multilib toolchain fixes 1. On SuperH, configuring GCC with explicit variant of the CPU (like "sh4") limits the default set of multilibs to just that CPU and requires --with-multilib-list to change. Allow for "unspecified" variant, so that we can defer to GCC to determine the list. 2. Support toolchains with both endiannesses at the same time. 3. Add a SuperH/newlib sample 4. Add more flags processing for uClibc Signed-off-by: Alexey Neyman <stilor@att.net>

sh: require multilib Now that libc backend installs the libraries into the directory reported by gcc as 'multi-os-directory', sh4 libraries are installed into a '!m4' subdirectory. This directory then confuses GNU ld, which assumes the exclamation mark to be a word separator and attempts to link to '/usr/lib' (a directory). However, if multilib is enabled, the default libraries are installed into the [expected] '/usr/lib/./'. This looks like an artifact of SuperH's unique way of specifying the multilibs to be built in GCC (which may list exclusions, starting with '!'). Signed-off-by: Alexey Neyman <stilor@att.net>

Switch gen-kconfig to new framework Also: - Move companion_* to comp_* to match the kconfig symbols - Replace bootstrap with former gen-versions.sh - Fold *.in.2 into their respective first parts; this moves common options to the end - if it is undesirable, inclusion of *.in can be moved where *.in.2 used to be (but that will also move version selection after common options). - Retire addToolVersion.sh (may later replace with a more comprehensive script that tries to download the added tarballs, copy the patches and try to apply them, and create a version.desc).

If left unspecified, GCC will determine the set of multilibs to compile automatically
based on selected endianness, FPU mode and OS.
