How to make the address of varients are assigned immediately in the memory?

["Elva Wang" <wangtingting at linuxda dot com>]

Hi,gcc groups:

    what configurations or options can make the compiler assigned sequential memory for short and long type data defined immediatly.

    For instance, I defined a structure {short,long ,short,short},if I only use gcc to compile the c file.

the memory size of the struture is 12 bytes, not 10 bytes. This means the memory block is not full occupied. How can I make it full occupied.

 

Best Regards!
