Forum Post: RE: Very inefficient code generation: FUNC_ALWAYS_INLINE pragma ignored and overhead from unexpected conditional code

Some additional comments that may prove helpful ... When you build for a C66x device by using the build option --silicon_version=6600, the default ABI is the newer EABI, and not the older COFF ABI.  When you build for a C674x device with --silicon_version=6740, the default ABI is COFF ABI, and not EABI.  This difference in ABI is why it is possible for the calling convention to be different.  

Thanks and regards,
