pragma option for packed

preetuabraham — Thu, 02 Feb 2017 17:55:45 GMT

Hi,

I would like to know the settings for changing this pragma to a different below in Code warrior 10.x for Cold fire processor MC5485 processor ,since the below line is throwing an error that it is an illegal pragma

//#pragma options align=packed. This was working in Metrowerks Codewarrior

Whether we can use #pragma options align= coldfire instead of the packed

Hi,

As per the MCU_Codlfire_Compiler.pdf(page no:355), I think the equivalent pragma directive is

#pragma pack (0 | n | push | pop) , where n is 1, 2, 4, 8, or 16.

So anyone from Codewarrior ,correct me if I am wrong .

Pelase clarify whether if n is 2 ,whether it is 2 byte alignment for structures and if n is 4 ,whether it is 4 byte alignment for structures
