I used the simple program provided in the gcc help pages.
i am using gcc-4.2.0 cross compiler for ARM (I think the problem
should persist in native compilers as well)
------------a.c--------
#include <stdio.h>
int main(void) {
static int a __attribute__ ((section (".offsets"))) = 0;
static int myname __attribute__ ((section (".offsets"))) = 0 ;
//static char stack[10000] __attribute__ ((section (".stack"))) =
{ 0 };
static int init_data __attribute__ ((section (".prems"))) = 0;
printf("Hellow world %d\n", 0);
return 0;
}
---------------------------
---------------a.cc----------------
#include <stdio.h>
int main(void) {
static int a __attribute__ ((section (".offsets"))) = 0;
static int myname __attribute__ ((section (".offsets"))) = 0 ;
//static char stack[10000] __attribute__ ((section (".stack"))) =
{ 0 };
static int init_data __attribute__ ((section (".prems"))) = 0;
printf("Hellow world %d\n", 0);
return 0;
}
-------------------------------------
The files 'a.c' and 'a.cc' are the same except that the 'a.cc' is
treated as c++ file.
in a.o created from 'a.c' has the sections. but the a.o created from
'a.cc' doesn't have
command used:
arm-none-linux-gnueabi-gcc -c a.c
arm-none-linux-gnueabi-gcc -c a.cc
Please let me know if I am wrong here, or let me know if there is a
workaround to make the 'a.cc' to have the sections compiled in.
