rodata section

Hi all,

I am new to this gcc-porting field. Please help me in how to make 
compiler emit '.rodata' section as like ARM emits when we have a 
initialised array in C code.

Basically tell me what macros are related that i need to put so for 
rodata section. I too tried by putting some macros but not able to do.

If there is anything else that is also required please tell me that too.

Thanks in advance,
Rajiv
