Well, both GCC 3.3.4 and 3.4.0 for
volatile unsigned char __sparc32_atomic_locks[64]
__attribute__ ((nocommon, section (".gnu.linkonce.b.__sparc32_atomic_locks"),
visibility ("hidden")));
generate
.section ".gnu.linkonce.b.__sparc32_atomic_locks",#alloc,#write
and not what you wrote, so what the code does ATM is really needed, otherwise
the whole .bss section becomes SHT_PROGBITS.
Even current gcc-3_4-branch sparc.c has /* ??? Handle SECTION_BSS. */
in sparc_elf_asm_named_section and so does GCC HEAD (and I don't see how
CVS GCC even does anything about comdat groups on SPARC at all).
So my guess is you are using some local hack.
So you clearly are us
