I've got a file test.c:
volatile unsigned char __sparc32_atomic_locks[64]
__attribute__ ((section (".gnu.linkonce.b.__sparc32_atomic_locks")));
Now I'm using gcc 3.3.5 and I generate assembler:
.file "test.c"
.globl __sparc32_atomic_locks
.section .gnu.linkonce.b.__sparc32_atomic_locks,"aw",@nobits
.align 32
.type __sparc32_atomic_locks, @object
.size __sparc32_atomic_locks, 64
__sparc32_atomic_locks:
.zero 64
.section .note.GNU-stack,"",@progbits
.ident "GCC: (GNU) 3.3.5 (PLD Linux)"
Looks ok. And now let's do the same thing with gcc 3.4.3 20041008:
[builder2@storm builder2]$ cat test.s
.file "test.c"
.globl __sparc32_atomic_locks
.section .bss,"awG",@nobits,.__sparc32_atomic_locks,comdat
.align 32
.type __sparc32_atomic_locks, @object
.size __sparc32_atomic_locks, 64
__sparc32_atomic_locks:
.zero 64
.section .note.GNU-stack,"",@progbits
.ident "GCC: (GNU) 3.4.3 20041008 (prerelease) (PLD Linux)"
Obviously the second example is broken. Is this some kind of changed syntax
(haven't found anything about it with google) or just a plain bug?
(either way it breaks glibc build and I really need that glibc :)
