cmake: Add xcc-clang toolchain Instead of setting XCC_USE_CLANG=1, this patch adds xcc-clang toolchain that is basically xcc using the clang compiler. Initially, the new toolchain simply includes files from current xcc toolchain and (re)sets some variables. This should be a more scalable approach to diverge the toolchains in the future than placing "if($ENV{XCC_USE_CLANG})" at several places. It should also help to filter tests that run (or not) exclusively with the clang variant of XCC on twister. The XCC_USE_CLANG flag is documented as deprecated, and a message is emitted during build if still in use. Its new behaviour is to instruct Zephyr to use `xcc-clang` toolchain.

llext: xtensa: add support for the xt-clang toolchain To build LLEXT images using the xt-clang toolchain from Cadence linker flags have to be set similar to other toolchains. Add the missing cmake files. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com> 2024-05-17 14:53:06 +02:00
