Combine toolchains provided by the host into one variant. This includes both gcc and llvm installationt typically coming from the distribution (on Linux). Both gcc and llvm are now part of the 'host' variant, the default is the gnu compiler, so setting ZEPHYR_TOOLCHAIN_VARIANT=host Will select the gnu compiler. To select llvm or any other compuler provided in this variant, use the follwoing format: ZEPHYR_TOOLCHAIN_VARIANT=<variant>/<compiler> The following will select llvm: ZEPHYR_TOOLCHAIN_VARIANT=host/llvm Although gnu is the default, it can also be selected using the above syntax: ZEPHYR_TOOLCHAIN_VARIANT=host/gcc This commit removes the llvm variant for now, it should be deperecated in another commit to follow.

The version number of C++ standard being used (NOTE: this uses the
|
|
full year and month, and is the same as the __cplusplus macro defined
|
|
by the compiler). This config can be used to check for a minimum
|
|
supported version. Example:
|
|
|
|
depends on STD_CPP_VERSION >= 201703
|
|
|
|
Adding this to your library's enablement Kconfig will force a minimum
|
|
c++17 standard.
|
|
|
|
The full year is used so c++98 can be checked using > and < operators
|
|
without conflicting with c++11 or higher.
