NOLOAD problem with binutils 2.16.92 |

Hi,
I am facing a problem in binutils 2.16.92.
Please refer to the code and the linker script below.
CODE:
-----
char ldTest __attribute__ ((section("TEST")));
int main(void)
{
ldTest = 5;
}
LINKER SCRIPT:
--------------
.bss :
{
_bss = .;
*(.bss)
*(COMMON)
_ebss = .;
_end = .;
}
.stack 0x00083800 :
{
_stack = .;
}
TEST 0x00FFEC00 (NOLOAD) :
{
*(TEST)
}
In the Linker script the user defined section "TEST" is assigned as
NOLOAD. Here it is expected that "TEST" section to behave same as
".bss" section.
When above code is linked using the binutils 2.16.92, "TEST" section
is assigned PROGBITS type whereas ".bss" section is assigned NOBITS
type.
But when the same code and linker script are linked using binutils
2.16.1 then the "TEST" and ".bss" sections are assigned as NOBITS
type.
Below are the results observed:
Section Headers:
[Nr] Name Type Addr Off Size ES Flg Lk Inf Al
.
.
[ 8] .bss NOBITS 000827c4 00203c 00002a 00 WA 0 0 4
[ 9] TEST PROGBITS 00ffec00 00203c 000001 00 WA 0 0 1
.
.
.
TEST section is assigned PROGBITS instead of NOBITS when linked using
ld (binutils 2.16.92).
Section Headers:
[Nr] Name Type Addr Off Size ES Flg Lk Inf Al
.
.
[ 9] .bss NOBITS 00082740 001de6 000046 00 WA 0 0 4
[10] TEST NOBITS 00ffec00 001de6 000001 00 WA 0 0 1
.
.
.
TEST section is assigned NOBITS when linked using ld (binutils
2.16.1).
This problem exists on both SH and H8/300 targets.
Please let me know why this is happening and any solution to fix
this problem.
