Assembler in rtx_core_ca.h is on the whole unified syntax such that it should work fine if assembled as either ARM or Thumb-2. The exception was __get_PSP, which uses STM^, which is only available in ARM state. Flagging for this function was incorrect, except for IAR - it switched assembler state without telling the compiler, meaning that the resulting assembler output could be incorrect, and that the function itself would not be correctly marked as an ARM function - the CPU would enter in Thumb state. Alternative fix would be to switch to System mode, which would work as either ARM or Thumb-2 assembler, like the rest of the file, but this is the minimal change. Fixes #526. |
