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

------- Additional Comments From pinskia at gcc dot gnu dot org 2003-08-08 16:25 -------
On the mainline (20030728) with a cross-compiler to mipsisa64-unknown-elf, I get the
expected results of fred and foo being in BSS (Really sbss, I do not know if this makes a
difference). But with 3.3.1 (20030714) I can confirm the beviour that the report is about.
Since emitting into bss is new for 3.3, I am closing this as fixed.
