Rasmussen, Torsten
 

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.
