           Summary: -fdata-sections put everything into the data section not
                    BSS
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: andrew dot lunn at ascom dot ch
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: mips64vr-unknown-elf

~$ cat bss.c
int foo;
static int bar;
int fred=1;

~$ /opt/ecos/gnutools/mips64vr-elf-3.3.1/bin/mips64vr-elf-gcc -save-temps -o
bss.o -c bss.c -fdata-sections

~$ cat bss.s 
        .file   1 "bss.c"
        .section .mdebug.abiO64
        .previous
        .globl  fred
        .section        .sdata.fred,"aw",@progbits
        .align  2
        .type   fred, @object
        .size   fred, 4
fred:
        .word   1
        .globl  foo
        .section        .data.foo,"aw",@progbits
        .align  2
        .type   foo, @object
        .size   foo, 4
foo:
        .space  4
        .section        .data.bar,"aw",@progbits
        .align  2
        .type   bar, @object
        .size   bar, 4
bar:
        .space  4

foo and bar should be in the bss, but with -fdata-section they end up in the
data section making the executable binary huge and mostly 0's
