This is an issue for tracking progress on building Contiki-NG with a recent build of Clang and recent MSP430 sysroot from TI.
Examples from both Contiki-NG and FreeRTOS seem to refer to some obsolete version of msp430-gcc, so they are not straightforwardly buildable by recent msp430-elf-gcc.
After updating them, the hello-world example from Contiki-NG does not fit into flash used by sky and z1 boards. I suppose maybe they were not tested with such a general purpose example (that starts IPv6 stack aside from printing "Hello world!"...).
in430.h header from TI sysroot contains code such as
First, it requires passing -fheinous-gnu-extensions to compile. Second, the { character is an instruction separator in MSP430 asm, so NoAsmVariants = true; should be set in clang/lib/Basic/Targets/MSP430.h, so this code is correctly parsed by Clang.
