Today’s MoM:

Notes/Minutes

• LLVM
• #24917, infrastructure in place and works, when linking with GNU ld.
• Work needed regarding:

• Linking with llvm-ld (log2ceil)
• Linking with llvm-ldd
• Compiler-rt
• Zephyr SDK
• Beta Zephyr SDK 0.12 last week
• Outstanding issue on Zephyr side, arm64, #28650
• ARC / TLS support ?
• On ARC the build itself doesn’t seem to enable it.
• Eugeniy will look into this.
• Cleanup and add Kconfig regarding TLS support, default to `n`
  Also allow users to specify if he know the toolchain support TLS
• Newlib should be part of this cleanup   
• Are we mixing Kconfig too much with toolchain properties ?
• Having information in both places, having CMake drives the Kconfig values ?
• Nothing happening on new packaging regarding Windows / macOS platform
• No further work is expected to happen regarding Zephyr SDK for Windows / MacOS, unless someone has the time and volunteers to drive this forward.
  It’s better to focus resources on better toolchain support, such as LLVM.
