Compiler Pragmas to allocate object to a section

From GCC manual:
extern void foobar (void) __attribute__ ((section ("MY_DATA_FOO")));

I am not sure whether we can do this in gcc by using pragma,
but yes,
objects/functions can be put into special sections using "__attribute__".
For example,
int init_data __attribute__ ((section ("INITDATA"))) = 0;
will put init_data in section INITDATA.

For more information, please refer to gcc manual, sections
"Declaring Attributes of Functions/Variables".

Thanks.
